2. IBC High precision angular contact ball bearings
IBC high precision angular contact ball bearings have been designed for all rolling bearing applications that make great demands on reliability, stiffness, speed capability and running accuracy; either as a single requirement or as a combination of the above. The many different types available allow spindle manufacturers across different sectors of industry as well as special-purpose mechanical engineering firms to optimise their spindles by focusing on the aspects that are most important to them. Technology and economic efficiency thus meet to form a winning combination. In order to achieve both improved performance and reduced costs for rolling bearings, the many application-specific requirements for running accuracy, load carrying capacity, rotational capacity, stiffness, vibration characteristics and installation space call for a whole variety of bearing series, each providing different solutions and dimensions that have different design characteristics.
high precision angular contact ball bearings from dimensional series 19, as these have the greatest possible number of rolling elements and allow for large shaft diameters with a given outside diameter. Contact angle The contact angle is defined as the angle between an imaginary straight line joining the points of contact of the rolling elements with the raceways and a line perpendicular to the rotational axis. IBC has tailored the internal design of its high precision angular contact ball bearings to the diverse requirements of the machine tool building industry. IBC therefore offers as standard high precision angular contact ball bearings with three different contact angles. Each dimensional series is designed with a contact angle of 15°, 25° or 30°. The high-speed angular contact ball bearings (H and CBH design) have a contact angle of 18°.
Dimensional series The IBC product range contains many different variations of single-row high precision angular contact ball bearings.

Fig. 2.1: Dimensional series for IBC high precision angular contact ball bearings
According to the German standard DIN 616 each type is assigned a dimensional series that consists of a diameter series and a width series. The dimensional series defines the outside diameter D, the bearing width B and the corner radii ‘r’. The identification number for the dimensional series is prefixed by the code “7”, which stands for “angular contact ball bearing”.
The different contact angles meet individual requirements for combined loads with regard to stiffness and rotational speed characteristics. IBC also manufactures precision angular contact ball bearings with contact angles of 35°, 40° and 60°. You will find information on these bearings in the publications Angular Contact Ball Bearings 40° TI-I-4044 and Ball Screw Support Bearings TI-I-5010. Designs As variants to the standard design, angular contact ball bearings can be supplied with smaller or ceramic rolling elements in order to achieve higher speeds.
Each dimensional series has special characteristics that make it suited to certain types of rolling bearings. Dimensional series 18 is the series with the smallest cross-section for high precision angular contact ball bearings; this series is designed for the highest speeds with simultaneously low requirements for load carrying capacity. There is an increase in overall width and outside diameter with dimensional series 19, 10 and so on. Dimensional series 19 and 10 are used for higher speeds or small radial cross-sections, whereas dimensional series 02 and 03 are used for high loads with relatively low speeds. If great demands are made on the stiffness of rolling bearings, it is usually best to choose

Fig. 2.3: The standard, CB, H and CBH design from the same dimensional series

So-called hybrid bearings retain the original bearing geometry but are equipped with ceramic rolling elements. The high-speed H design utilises smaller rolling elements within an unchanged outer geometry; the CBH design combines both smaller and ceramic rolling elements. The CBH design is suitable for the highest speeds, but does not have such a high load carrying capacity. Hybrid bearings equipped with ceramic rolling elements and rings made of bearing steel are used not only in high-speed applications; their many advantages also include their reliability and their extended grease service life. The combination of harder and lighter ceramic rolling elements reduces the rolling bearing’s heat output and the wear of the lubricant. They also improve rolling conditions in an unfavourable lubrication environment and provide insulation to prevent electrical current flowing through the bearing. This leads to greatly reduced system costs. IBC Wälzlager GmbH has also made wide-ranging additions to dimensional series 19 and 10 supplementing them with an optimised generation of rolling bearings with the suffix X (CX and EX). As can be seen, this variation is identified as an extension to the contact angle designation. The purpose of this design is to close the gap between the standard and high speed series, by providing bearings that are closely matched and controlled. This new design is characterised by low frictional torque, leading to significantly reduced heat emission, as a result of design techniques applied to the inner bearing geometry. Sealed IBC high precision angular contact ball bearings As a result of the increasing demand for grease-lubricated high precision angular contact ball bearings, IBC have extended their range of sealed high precision angular contact ball bearings that are greased ready for use. The standard lubrication fill, implemented during the manufacturing process, ensures the optimal grease type and quantity are applied, which has a positive effect on bearing life and machine performance. IBC high precision angular contact ball bearings are filled with suitable high-performance grease as standard that covers a wide range of operating temperatures. The bearings are ready for immediate installation and operation, subject to normal grease running-in procedure. Further information on this topic can be found in Chapter 7 (Lubrication).
The high precision angular contact ball bearings are ideally protected against contamination and air currents due to being sealed with non-contact seals (2RSZ) on both sides. These seals do not limit the suitability of the bearings for high rotational speeds, and in the case of vertical or pivoting spindles the seals additionally act as grease retention washers. The rolling bearings from dimensional series 18 and 19 as well as H execution bearings come with a standard lubrication fill of GS36 grease; all other bearings come with a standard lubrication fill of GS75 lubricant. There is no special marking for the standard lubrication. The permitted operating temperature of these seals, which are made of oil-resistant and wear-resistant acrylonitrile butadiene caoutchouc (NBR) and are supported by a reinforced steel plate to provide rigidity, lies between -40° and 120°C. Oil/air lubrication Oil/air-lubricated high precision angular contact ball bearings are axially supplied with an oil/air-mixture via intermediate rings. The reference circle for the required lubrication input is detailed in the dimension tables. No changes need to be made to the design of the rolling bearings themselves.

Special designs Should grease-lubricated high precision angular contact ball bearings be required to run at or above their limits, IBC high precision angular contact ball bearings with outer ring lubrication are an ideal option.
x51-201
Cages As standard, IBC high precision angular contact ball bearings are equipped with a fabric reinforced phenolic resin cage that already meets the requirements of many types of application. If the high precision angular contact ball bearing is subject to special operating conditions, like high temperatures or extreme accelerations, we provide suitable cages made of alternative materials. Please contact us if your application needs a special type of cage. A detailed description of the individual cage materials is included in Chapter 9 (Materials).
Fig. 2.5: IBC high precision angular contact ball bearing lubricated via the outer ring
A circular groove and a radial supply hole permit direct lubrication. O-rings integrated into the outer ring act as a seal for the housing. The dimensions of the grooves and recesses are contained in Chapter 7 (Lubrication). High precision angular contact ball bearings with outer-ring lubrication reduce the number of elements that are part of structure around the bearing, leading to savings in installation space and cost reduction. Apart from the designs mentioned, IBC also produces a number of specially designed high precision rolling bearing variations. Should you be interested in such a design, please contact our technical customer support teams. We will be glad to help you find a solution to meet your specific bearing requirements. Bearing materials Rolling bearing rings and rolling elements are generally manufactured from vacuum degassed bearing steel 100Cr6 (1.3505). Ceramic rolling elements are also available in the ceramic material silicon nitride Si3N4. A detailed description of materials can be found in Chapter 9 (Materials). Heat treatment The bearing rings are, as standard, stabilised up to a service temperature of 150 °C. Higher-quality heat treatment is available upon request for higher temperatures. More detailed explanations on this, e.g. types of treatment, restrictions and suitability, are contained in Chapter 9 (Materials).

Bearings with ATCoat coating In addition to the executions already mentioned, IBC also manufactures high precision bearings with an ATCoat thin dense chromium coating. You will find a more detailed description of the ATCoat coating in Chapter 10 (IBC High precision rolling bearings with ATCoat coating) and particularly in the publication ATC Technology Coatings.
Special mention should be made of the ATCoat thin dense chromium coating of the outer ring in the case of a high precision angular contact ball bearing that is used as a floating bearing. In this case the coating prevents fretting corrosion if the outer ring of the high precision bearing requires a fit that is not too tight, to allow for axial displacement.

2.4 Preload and stiffness
A machine tool is seldom a single purpose machine. Based on this a spindle can not be sized to meet a single set of boundary conditions. Eventually sizing a machine tool spindle is based on the total range of the basic application of the machine. If the machine is a multipurpose machine each critical operational condition needs to be calculated.
align the faces of inner and outer rings; the rings are slightly offset against each other when the single bearing is in an unloaded state. The bearing thereby becomes elastically deformed without, however, sustaining damage.
If high precision angular contact ball bearings are mounted in sets, the ground-in preload essentially determines the characteristics of speed, heat and stiffness. However, high rotational speed and great stiffness are contradictory characteristics. So the best possible compromise needs to be considered. There have been examples where extremely sophisticated bearings have been designed with elaborate hydraulic devices to create variable preloads In order to meet diverse requirements, the high precision angular contact ball bearings have therefore been developed not only with different-sized rolling elements, and thus different load ratings, but also with different preloads. The default preloads have been designated as X for extra light, L for light, M for medium, and H for high preloads. This grading is suitable for the great majority of applications. X
M
The reciprocal of bearing elasticity is stiffness. Stiffness indicates the resisting force of a preloaded bearing in newtons over its spring deflection in µm. Preload and stiffness are interdependent. As a rule, the stiffness of a bearing does not increase in a linear fashion in relationship to the preload. The axial and radial stiffness of a pair of angular contact ball bearings depends both on the preload and the contact angle. The following table-values specify the axial stiffness Sa and the radial stiffness Sr for each individual angular contact ball bearing. The same values are true for a pair of angular contact ball bearings of the same type that are set against each other. The relevant factors needed to calculate the preload and stiffness for further sets of high precision angular contact ball bearings are contained in Chapter 2.7 (IBC High precision angular contact ball bearing sets).
L
The preload stresses the high precision bearings in the same way as outside axial forces do. In dimensioning the rolling bearing, quite often a good balance needs to be struck between preload and stiffness on the one hand and attainable speed and life time on the other.
H
Due to the lower static load-carrying capacity of the ceramic rolling elements as compared to standard bearings of the same geometry, high precision hybrid rolling bearings have slightly lower preloads. But the stiffness of hybrid bearings is still significantly higher at identical preload, because ceramic rolling elements are harder. x51-114
Fig. 2.6: Preload of IBC high precision angular contact ball bearings
The preload of a high precision angular contact ball bearing is defined as the axial force that needs to be applied in order to
The values for axial and radial stiffness contain parameters that are affected by tolerances that relate to the manufacturing process. The actual stiffness of a rolling bearing may only be determined when it is fitted in its individual mounting situation. For this reason the values in the tables have been rounded up or down; the values are only meant to be used to compare the different kinds of high precision rolling bearings with each other.

2.5 Differential measurements for preloads
In order to attain the required stiffness for a bearing’s given rotational speed it may become necessary during spindle adjustment to adjust the built-in preload. This can be achieved with the aid of spacer rings whose difference in length leads to a change in preload class.
x51-602
Fig. 2.7: IBC high precision angular contact ball bearings with spacer rings
The differential measurements of the individual preload classes relative to each other are given in the following tables for this purpose. The differential measurement is the distance in µm by which the rings of a single angular contact ball bearing is additionally axially displaced relative to one another in order to achieve the next preload class. For an O-arrangement, for example, shortening the inner spacer ring by the value given in the table makes the preload move up into the next higher class. In an X-arrangement, the same is true for the outer spacer ring. The preload is reduced if the procedure is carried out the other way round. The measurements of custom-built spacer rings should be carefully documented, and the rings should be kept with the spindle even during repair work. If the spacer rings need to be replaced, the existing differential measurement needs to be determined in order to restore the previous preload with the help of the given differential measurement of the high precision bearings that need to be replaced. Should the bearing need to carry higher loads, spacer rings that measure the width of the bearing permit subsequent trouble-free insertion of a further rolling bearing.

2.6 IBC High precision universal angular contact ball bearings All IBC high precision angular contact ball bearings are universally ground. They may therefore be used singly and can be combined to a bearing set arrangement defined by the end-user without any loss of performance. Using universal angular contact ball bearings is a great advantage, especially from the point of view of stocks and the availability of components. Universal angular contact ball bearings are manufactured as single bearings known as U, and as duplex sets known as DU. Single bearings are marked with a V-marking on the outer ring that allows one to recognise the direction of axial force more easily. The V-marking points in the direction in which the axial force is transmitted through the outer ring. The V-marking also indicates the point of maximum ring thickness. The advantage of universal bearing-sets lies in the fact that their bores and outside diameters are sorted as standard in the IBC manufacturing process. During manufacture, IBC universal angular contact ball bearings are adjusted and matched in such a way that they can be mounted in any type of arrangement (O- or X-arrangement, or tandem mounting) and with any number of bearings positioned next to each other.
+
The bearing arrangement is carried out by the customer with the help of the small arrow marker. In order to facilitate mounting, we also manufacture sets with an additional V-marking that runs on the outer rings, e.g. DB, TBT, QBC, and other combinations. This is explained in more detail in the following Chapter 2.7 (IBC High precision angular contact ball bearing sets). x51-202

2.7 IBC High precision angular contact ball bearing sets
The minimum mounting for a spindle consists of one high precision angular contact ball bearing on each side. Both bearings are therefore arranged at a suitable distance from each other. In this arrangement, the required preload adjustment is carried out by means of a suitable locknut with a defined tightening torque or with a suitably ground flange cover. The correct adjustment of the two individual high precision angular contact ball bearings is crucial for the successful operation of this type of bearing arrangement. If the adjustment is not carried out correctly, the life time of the bearing may be reduced through higher friction losses and associated higher operating temperatures. If the load carrying capacity of a single bearing is insufficient, or should the bearing need to absorb axial forces in both directions, then high precision angular contact ball bearings with universally ground-in preload can be used in sets. During manufacture, IBC high precision angular contact ball bearing sets are pre-adjusted and matched to each other in such a way as to maintain the predefined preload value of a single bearing within the set and to ensure that the load bearing capacity within the angular contact ball bearing set is spread evenly across the individual bearings.
That is why angular contact ball bearing sets with this type of arrangement produce a relatively rigid bearing. In contrast to the O-arrangement, the effective load centre in the X-arrangement is narrow and the X-arrangement is therefore less rigid but slightly more tolerant towards tilting. With tandem mounting, the contact lines run parallel to each other and at the same angle to the separating line of the angular contact ball bearing. IBC also offers other high precision angular contact ball bearing sets. Should the design used not permit the setting of angular contact ball bearings in tandem mounting against a further contact ball bearing, or against another set of contact ball bearings, then it is possible to combine tandem mounting with an O- or X-arrangement, for instance. If there are special requirements with regard to stiffness and bearing load, then it is advisable to use tandem mountings with three or four angular contact ball bearings.

4.5 Radial clearance IBC High precision cylindrical roller bearings The values for the bearing clearance of high precision cylindrical roller bearings are different for bearings with cylindrical bore from those with tapered bore, even if they belong to the same tolerance class. When fitting a high precision cylindrical roller bearing on to a tapered shaft it is possible to adjust the bearing clearance specifically via the displacement. This option, and the simple design, make high precision cylindrical roller bearings ideally suited for use in the machine tool industry. Further information on this issue is contained in Chapter 8 (Mounting of High precision rolling bearings).
As standard, IBC manufactures high precision cylindrical roller bearings to conform to the tolerance class SP with radial clearance C1. The bearing clearance is not explicitly specified. Apart from the class mentioned, further bearing clearance classes are available, e.g. SPC2X or C3. The bearing rings of high precision cylindrical roller bearings of the same type are not interchangeable.

The positional accuracy and form accuracy of the adjacent parts must be adjusted to the accuracy requirements of the high precision rolling bearings. Rolling bearings adapt to form deviations in the shaft and the housing because the bearings have comparatively slender ratios of cross section.

5. Life time calculation
Even under suitable operating conditions, and even if the high precision rolling bearings have been mounted properly, a bearing may still fail. The service life of high precision rolling bearings is limited by various factors.
Basic rating life
The length of time during which a high precision rolling bearing works satisfactorily is called its “life time”. Material fatigue, vibrations, contamination or lubrication-failure may occur during this time span. In the following observations we will be ignoring the causes that can lead to the failure of a high precision rolling bearing without noticeable prior indication; these causes include faulty design, inadequate maintenance, faulty mounting, and wrong bearing dimensioning. Fatigue Fatigue of the material that high precision rolling bearings are made of is caused by the rising stress to the material that occurs when high precision rolling bearings rotate under load. Towards the end of the life of the bearing, “pittings” appear on the running surfaces or the rolling elements; an initial occurrence may be followed by progressive pitting of the material. Various factors are responsible for material fatigue; they can really only be covered with reference to statistics. The definition of a theoretical reference value for “fatigue life time” therefore refers to a very large quantity of rolling bearings running under the same conditions. The fatigue life time is reached as soon as 10% of all bearings have failed. The fatigue life time may be specified with reference to the number of revolutions or to the runtime in hours. In addition to fatigue life time, lubrication life time is another decisive factor in operating a high precision rolling bearing. Particular rules apply for the calculation of this factor. In the case of high precision rolling bearings that are permanently monitored, other parameters may also be crucial in determining their life time, including temperature, bearing noise and vibrations.
In terms of pure definition, 10% of a great number of high precision rolling bearings of the same type, running under the same conditions, may fail within a basic rating life of L10. If a constant rotational speed is used, the basic rating life may also be specified in terms of a time L10,h.

Dynamic load rating The dynamic load rating is the constant load of a high precision rolling bearing with a rotating inner ring for which 1 million revolutions will be achieved with a probability of 90%. It is considered as a central radial load that is constant with regard to magnitude and direction. It is based on numerous experiments and is a performance figure that may be calculated with the aid of empirical rules. Static load rating The static load carrying capacity of a high precision rolling bearing is defined by the static load rating C0. This is the load that a stationary high precision rolling bearing can bear with a maximum permanent plastic deformation of 1/10,000 of the rolling element diameter.

Equivalent dynamic bearing load Combined loads, comprising both axial and radial components, can often act on high precision rolling bearings. In order to relate the forces that actually act on a high precision rolling bearing to the dynamic load rating, the equivalent dynamic bearing load P is calculated from the effective force components. This load is hypothetical and corresponds to the dynamic load rating with regard to the point of application of the load and its effective direction. P = X · Fr + Y · F a

Comparing the effective static bearing load with the static load rating also means that the equivalent static bearing load P0 has to be calculated. Calculation is done in analogy to the calculation of the equivalent dynamic bearing load. P0 = X0 · Fr + Y0 · Fa

Once you have calculated the equivalent dynamic bearing load it may be mathematically related to the dynamic load rating in order to determine the life time. Equivalent static bearing load The necessary static load rating C0 is calculated from the equivalent static bearing load P0, which is additionally weighted by the static load safety factor s0. C0 = P 0 · s 0

Achieving adequate static load safety depends on the operation of the rolling bearings and on their required running smoothness. High precision angular contact ball bearings require a minimum static safety factor of 1; high precision roller bearings require a minimum static safety factor of 1.5. If high demands are placed on the running smoothness of the rolling bearing, the above mentioned values for static load safety must be at least doubled. If the rolling bearing is subject to shock impact loads, an additional increase of the static load safety by factor 1.5 is required. Static load carrying capacity of dynamically designed bearings If the static load is known, the equivalent static bearing load should be calculated for the type of rolling bearing that was chosen on the basis of the computation of the dynamic load carrying capacity; the equivalent static bearing load should then be checked against the static load safety given above.

Determining the axial and radial load factors To begin with, the axial and radial load factors from table 5.1 are determined for angular contact ball bearings that permit a combined load. The first step for angular contact ball bearings with a contact angle of 15° is to calculate the ratio Fa / i · C0. In so doing, i stands for the number of high precision rolling bearings in a set. The bearing-related factor e for single bearings or bearing sets with the same alignment is given in table 5.1a; for high precision rolling bearings that are set against each other, the factor e is given in table 5.1b next to the value that comes as close as possible to the outcome of the calculation Fa / i · C0. The factor e may also be interpolated in the relevant manner. In the next step, the ratio of the force components Fa / Fr that impact from the outside is calculated and is compared to the value of the bearing-related factor e that is contained in the respective table. If the ratio is smaller than e, then the axial component is omitted and only the radial load factor X = 1 is retained. If the ratio is greater than e, then the factors X and Y are read off from the same line in the table as their respective factor e. In the case of angular contact ball bearings with a contact angle of 25°, e always has the value of 0.68, and the ratio Fa / i · C0 is not calculated. The static radial load factor X0 and the static axial load factor Y0 may be taken straight from tables 5.1a and 5.1b for the different kinds of contact angles and bearing arrangements. There is no need to calculate these factors. Contact angle

Re-lubrication In most cases, for-life grease lubrication is the option of choice. If multiple reduction factors limit grease life time, however, provision must be made for the option of re-lubricating the high precision rolling bearing. A suitably short re-lubricating period must apply in very adverse lubrication conditions. If this is not feasible, the high precision rolling bearings must be replaced in the context of planned maintenance, taking into account the above mentioned factors. In some cases, automatic re-lubricating systems may be used, that continuously dispense minimal and fixed amounts of grease. High precision angular contact ball bearings with a lubrication facility in the outer ring (S) may also be suitable for this procedure. In certain cases, the lubrication holes must be adjusted to suit the viscosity of the grease. In the case of fast-running rolling bearings, higher temperatures should be anticipated directly after re-lubricating. Depending on the method of insertion, the newly inserted lubricant first needs to be displaced from the contact area of the rolling elements to the raceways. If necessary, a new grease distribution run may have to be carried out. Oil/air lubrication This lubrication system is used to increase speed and operational safety. A minimum quantity of oil is mixed in a fixed ratio with compressed air in an oil/air lubrication unit; this mixture is then finely metered and fed to the bearing as per unit of time. The oil/air jet lubrication for high precision rolling bearings with cages guided on the outer ring is carried out between the cage and the inner ring at the injection diameter Dpi via a small nozzle that is either directed in parallel into the gap or is slightly tilted towards the inner ring. The latter method additionally helps to cool the inner ring – the component that is most exposed to heat.
The oil/air mixture, which is fed into the bearing in great quantity, must be able to escape from the rolling bearing, because oil residues can lead to overheating. In order to prevent stagnant oil from forming, discharge channels of an appropriate size must be provided for. If necessary, the oil/air mixture may be extracted by suction (vacuum). Before bringing into service a spindle lubricated by an oil/air mixture, it is absolutely necessary to ensure that during start-up the rolling bearing is lubricated by a minimum quantity of oil introduced in the course of the mounting process. Among the lubricating oils that are suitable are alloyed and nonalloyed mineral oils according to standard DIN 51501 and synthetic oils that have a high degree of cleanliness and contain oxidation inhibitors and foam inhibitors. The reference viscosity according to diagram 5.1 in Chapter 5 (Life time calculation) gives an approximate specification of the required viscosity. But because spindles are often used with a wide range of rotational speeds, many applications will require a compromise. A viscosity of about 7 mm²/s is necessary for spindles used with the maximum speed; spindles used within the medium speed range require a viscosity of about 17 mm²/s. Oils with a viscosity of < 13 mm²/s should contain EP additives that increase the pressure absorption capacity. If an oil/air lubrication system is used, oil viscosity will have little influence on heating because of the smaller quantity of oil that is involved. This permits the use of a higher viscosity ratio of κ > 3 and therefore of viscosities of 32– 80 mm²/s at 40 °C, that will help to increase life time.
For each oil jet lubrication ring a nozzle measuring 1 mm to 1.5 mm in diameter and roughly five times the length of the bore diameter is recommended. High precision rolling bearings that are lubricated via the outer ring present an alternative to this system. In this case, the outer ring of the bearing possesses a radially circumferential supply groove that is surrounded by two O-rings for sealing and at least one supply hole. These high precision rolling bearings are identified by an S after the contact angle designation.

The complex system of oil/air lubrication is used to achieve very high rotational speeds. If the stress to the rolling bearing is not too high, high precision angular contact ball bearings with smaller diameter rolling elements or rolling elements made of ceramics may also be used. With such rolling elements, even grease lubrication will yield significantly higher speeds when compared to angular contact ball bearings that have larger steel rolling elements.
Oil jet lubrication Oil jet lubrication is an even safer and an even more complex process. For this type of lubrication, a large amount of oil is supplied, about 100 times the quantity that is used in the oil/air lubrication system. In oil jet lubrication the oil simultaneously serves to dissipate heat. The high churning losses that ensue when this type of lubrication is used must be balanced by a higher driving torque. For further temperature reduction an interconnected oil recooling system may be used. For horizontal spindles, the jet velocity of the oil must amount to one quarter of the circumferential velocity of the air vortex that builds up. This velocity is needed so that the oil can break through the vortex. In the case of vertical spindles, however, the application of this type of lubrication is fraught with problems. With the aid of oil jet lubrication, even higher speed coefficients of over 3 · 106 mm/min can be attained with a minimal rise in temperature. The oils used for this type of lubrication have very low viscosity (about 3 mm²/s at operating temperature).

8. Mounting of high precision rolling bearings
Preparing the mounting area IBC High precision rolling bearings for high precision spindles are manufactured with the greatest care under ultra-clean conditions; they are subjected to intensive tests and are then packed in quality packaging in order to prevent transport damage and contamination.
A clean and dust-free working environment should also be ensured during mounting so as to be able to achieve the best possible running performance. Should fine dust or ultra-fine chippings penetrate the bearing, both the precision and the life time of the high precision rolling bearing will be adversely affected. Abrasive dust is especially aggressive and must be kept away by all means. It is advisable to wholly or partially cover the bearing place with protective foil if a break in the mounting process occurs or if mounting is very time-consuming. Under no circumstances should the bearing be touched with a fluffy cloth. The high precision rolling bearings should also be stored in their original packaging and should be kept safe from moisture or aggressive media. High precision rolling bearings should generally be kept and stored in a horizontal and not in a vertical position and should be fully supported. Mounting high precision rolling bearings with unsuitable or unclean tools or mounting aids will considerably affect the working of the high precision rolling bearings and will reduce their capability and life time. We would like to expressly draw your attention to the fact that IBC will assume no liability for damage that is the result of the mounting instructions not being observed and not being complied with. This also applies to the faulty interpretation or dissemination of the instructions as well as to faulty mounting and maintenance.
of the fact that in most applications the high precision rolling bearing is first mounted on the shaft and the outer ring of the bearing fitted afterwards. Preparing the adjacent parts Apart from checking for dimension and form accuracy, testing of the adjacent parts (housings and shafts) should also include a check for surface roughness of the bearing seats. In the case of tapered seats, the roundness, the taper angle and the straightness of the tapered surface outline should be checked too. If spacer rings or precision locknuts have been used, these should be checked to see if they run in parallel and are free of burrs and damage. Only faultless mounting parts guarantee the proper functioning of the high precision rolling bearing. If serial mounting is carried out for applications in the upper speed range, it is sensible to divide the tolerances of the housings and shafts into two or three groups. This will make allocating them to bearing sortings easier, a process that helps to achieve interference and clearance fits that are as identical as possible during mounting. Detailed information on the sortings of IBC high precision rolling bearings are contained in Chapter 4 (Tolerances). Preparing the high precision rolling bearings The high precision rolling bearings must be carefully checked before mounting. During this inspection the drawing details need to be compared to the bearing data on the packaging and/or the shrink-wrap foil. It is most important to prevent dust particles from entering the bearing. A dust-free mounting environment should therefore be ensured, and the protective foil should only be unsealed just before mounting the high precision rolling bearings. It is advisable to wear protective gloves when removing the high precision rolling bearings from the shrink-wrap foil, as hand perspiration may cause corrosion. High precision rolling bearings are available in the following three executions: ■ open, only preserved ■ open, greased and identified by the respective suffix (e.g. GS34) ■ sealed, greased and with non-contact sealing
Because there are so many different possibilities of mounting a rolling bearing we are unable to treat all options here, especially as such options are also very much specific to the design of the adjacent construction. The following remarks therefore make use
176

If lubrication of the high precision rolling bearings with grease is carried out by the customer, the customer should ensure the grease is compatible with the preservation oil that has been applied. If this is not the case, the bearing needs to be rinsed and then drained. Under no circumstances should a high precision rolling bearing be dried with compressed air. Suitable detergents may be used for rinsing. When using detergents, please observe the instructions for use supplied by the detergent manufacturer as well as the statutory provisions for occupational health and safety and environmental protection. x51-211
It should be noted that the choice of grease is of fundamental importance for the working of a high precision rolling bearing with respect to life time, noise level, operating temperature and rotational speed function. After making your choice, lubricate the bearing with the right quantity of suitable bearing grease, while taking into account the free space available and the intended speed. Information on the right amount of grease suited to each rolling bearing is contained in the grease quantity table 7.2 in Chapter 7 (Lubrication). During insertion of the grease, particular attention must be paid to greasing the space between the outer ring shoulder and the cage (friction surface). This can be done with a syringe, for instance. During lubrication, the high precision rolling bearing must be revolved several times so as to distribute the grease as evenly as possible. This will help to shorten the grease distribution run that is carried out afterwards.
Fig. 8.1: Indication of load direction
IBC high precision rolling bearings are in general universally ground. They may be put together in any arrangement during mounting. In addition to having individual arrow indicators, those sets of high precision rolling bearings that have been put together in our factory in a particular arrangement are marked with a continuous (large) V-marking that spans all the high precision rolling bearings in the set. These sets must be mounted exactly in the direction of the large V-makring and may not be split up. The point of the V-marking designates the mounting direction and the main load direction.
You should preserve the remaining bearing surfaces with the grease base oil or with preserving agents that are compatible to the base oil. Oil lubrication must be used if the limits of the operating conditions for grease lubrication have been exceeded. In order to prevent a potentially detrimental dry start-up in the case of oillubricated high precision rolling bearings, it is essential to apply a quantity of the selected oil directly into the high precision rolling bearing before mounting and operation.
x51-210
Fig. 8.2: Marked bearing set
Mounting in the right arrangement In preparation for mounting, the bearing arrangement must be checked against the drawing, and the bearing sets must be arranged accordingly. Because of their unsymmetrical design, angular contact ball bearings may only be loaded in one axial direction. Strict attention must therefore be paid to their direction while mounting angular contact ball bearings or sets of angular contact ball bearings. In the case of open high precision rolling bearings (see page 8), one outer shoulder has been ground clear for assembly. External loading is via the shoulder that has not been ground clear. An arrow on the outer diameter of the outer ring additionally identifies the load direction, just as in the case of sealed bearings.
177
Kap7.8_S164-S183_neu RZ2_E.indd 14
08.11.10 10:45
This also applies to high precision rolling bearings that have been put together to form high precision rolling bearing sets that are balanced with regard to their preload. The possible arrangements for high precision rolling bearings are described in Chapter 2.7 (IBC High precision angular contact ball bearing sets). Sets of high precision rolling bearings that have been put together in our factory with no particular arrangement are identified by the suffixes DU, TU or QU. These sets are packed together, and each bearing carries only an individual arrow indicator on the outer diameter of the outer ring. All high precision rolling bearings match each other with regard to their tolerances for bore diameter and outer diameter. This means that they feature the same sorting, i.e., they fall in the same tolerance zone for bore and outer diameter. Detailed information on this process is contained in Chapter 4.3 (Sorting and chamfer dimensions IBC high precision rolling bearings). All high precision angular contact ball bearings with the tolerances P4A, P2H and P2A are identified by the explicit specification of the mean values Dgm and dgm on the external packaging and the foil bag. The bearings are sorted into 2 or 3 groups within the allowed tolerance for bore diameter and outer diameter. This makes it easy to put together bearing sets with the same load bearing characteristics. Specifying the tolerance of high precision rolling bearings, and taking into account the known tolerances of shafts and housings, enables the user to put together combinations within a series of spindles that each have the same overlap of tolerance zones. Mounting process Induction heating of the high precision rolling bearing or heating via heated spacer rings is advisable for inner rings that have interference fits. The inner rings are expanded by this process, which makes mounting easier. If you carry out the heating with induction heating appliances, only the metal rolling bearing components will be heated, whereas the cage and the seals will remain thermally unaffected. It is absolutely essential to make sure the temperature of high precision rolling bearings that are to be mounted in a heated state does not exceed 80 °C. When mounting high precision angular contact ball bearings, the displacement force should be brought to bear directly on the ring which is currently to be mounted by means of a suitable tool; the displacement force should not be brought to bear indirectly via the counter ring and therefore via the intermediate rolling elements. Loading the rolling elements with mounting forces should generally be avoided. Start with the ring that has the tightest fit.
When fitting the bearing rings you should ensure that these are fitted tightly to the contact surface in order to avoid settling and misalignment. Such occurrences would lead to premature failure, because the bearings would be operating without preload. If high precision rolling bearings have been fitted to the shoulder in a heated state, the bearing rings must be pushed axially against the shoulder once again after they have been allowed to cool. Preloading the high precision rolling bearings/ tightening torques Preloading of high precision rolling bearings may be carried out with IBC precision locknuts, with a flange cover that has multiple screws on the pitch circle diameter, or with a central cap screw in the middle of a solid shaft. Preloading with precision locknuts If you are preloading high precision rolling bearings with a securable precision locknut with fine thread via the inner rings, the minimum required tightening torque MD that is needed to overcome the preload may be determined as follows: MD = 3 · dGewinde · FV · KFV · 10-4 MD dGewinde FV KFV
