2 IBC High-Precision Angular Contact Ball Bearings IBC HM and HM 70.. high-precision angular contact ball bearings have been developed in response to the continuing trend of higher speeds in machine tool spindles. These series can reach nearly the same speeds as the H-version and at the same time have almost the same load rating as the standard version. resolved with this design. Higher speed increases in comparison with the standard version Table 1: Speed factors for material and lubrication Factor ATCoat-coating (A11 eg. A15) 1,2 Ceramic rolling elements of Si 3 N 4 1,3 Oil-air-minimum lubrication 1,4 H HM Standard Load capacities Load capacities of the HM-versions fall in the middle between of the H-version and the standard version. This is a result of not only the slightly reduced ball diameter, but also the more open curvature contact points. Load rating comparison Figure 1: Comparison of internal design for each version x Speeds The high speed capability is made possible by an optimized internal design. In addition to the slightly reduced ball diameter in comparison with the standard design, the HM design has a more open curvature contact point that produces less friction and thus generates less heat. The high precision of the components, especially the races, also reduces the noise level during operation. Load ratings Bore diameter Diagram 2: Qualitative load rating comparison Standard HM H Speed comparison Technical properties HM-version high-precision angular contact ball bearings have the following features: Rotational speed Bore diameter Diagram 1: Qualitative speed comparison H HM Standard Series and 70.. Contact angle 18 (.C) and 25 (.E) Intermediate ball size Open curvature contact Tolerance class P4A Preload classes L, M and H or alternatively custom preload Bearing rings made of 100Cr6 steel Balls made of 100Cr6 or ceramic Si 3 N 4 (CB) Window type cage made of phenolic resin (.T) Optional non-contacting NBR seals on both sides (.2RSZ) ATCoat coating, optional (AC-, ACC-) 2

3 Materials and coating The bearing rings and balls are made of 100Cr6 bearing steel as standard. The optional use of ceramic balls Si 3 N 4 (CB) allows for the limiting speed to be increased by a further 30%. The combination of ceramic balls and an ATCoat coating (ACC-) has proven itself particularly advantageous in practice. This very providing for additional speed increases and lower temperature rise. It also protects against wear and corrosion. Outer ring located cages made of phenolic resin (.T) are used to is suitable for very high speeds. Lubrication The HM-version of the high-precision angular contact ball bearing is available with grease lubrication or oil-air minimum lubrication as an option. Tried and tested IBC spindle bearing greases GS36 and GS75, suitable for very high speeds are used with the grease lubrication option. For hybrid bearings in particular, GS39 grease can be used as an alternative. For oil-air minimum lubrication (.S), lubrication holes are made in the outer ring, through which the oil reaches the contact area between the raceway and the balls directly. In addition to increasing the limiting speed by about 40%, oil-air minimum lubrication through the outer race provides better heat dissipation. Bearing sets Like the standard and H-versions of the high-precision angular contact ball bearing, the universally ground HM-version is also suitable for installation as a single bearing or a bearing set in O-, X-, and tandem-arrangements. For bearing sets with three or more bearings, these arrangements can be combined with each other, depending on the load conditions. In addition to individual markings that identify the set arrangement directly, the bearing sets have an overall arrow marking on the surface of the outer rings that indicates the main load direction from the inner ring toward the outer ring. other IBC high-precision angular contact ball bearings.
