Technical Information: Ball bearing types, selection factors, and bearing …

Ball Bearings. There are several types of ball bearings that fit specific needs. The deep-groove ball bearing, Figure 2 (a), is the most versatile. Radial loads and thrust-load capacities may be approximately equal in this bearing. When it has the proper separator, it is very good for high-speed operation.
