For thrust bearings, the mounting dimensions should be carefully determined such that bearing race will be perpendicular to the support and the supporting area will be wide enough. For thrust ball bearings, the shaft shoulder diameter da should be larger than pitch diameter of ball set, while the shoulder diameter of housing Da should be smaller than the pitch diameter of ball set. (Fig. 14-6 Thrust ball bearings)

For thrust roller bearings, the housing/shaft diameter Da/da should cover the lengths of both rollers. (Fig. 14-7 Spherical thrust roller bearings)

Single row deep groove ball bearings are the most widely used bearing type and are particularly versatile. They have low friction and are optimized for low noise and low vibration, which enables high rotational speeds. They can accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than many other bearing types.

Mounting dimensions mean the necessary dimensions to mount bearings on shafts or housings, which include the fillet radius or shoulder diameters.Standard values are shown in "Table 14-2 Shaft/housing fillet radius and shoulder height of radial bearings". (The mounting related dimensions of each bearing are given in the bearing specification table.) The grinding undercut dimensions for ground shafts are given in "Table 14-3 Grinding undercut dimensions for ground shafts".
