Types of Bearings | Uses & Working Mechanisms Explained

25/8/2020· Ball bearings provide very low friction during rolling but have limited load-carrying capacity. This is because of the small area of contact between the balls and the races. They can support axial loads in two directions besides radial loads. Ball bearings are used for controlling oscillatory and rotational motion.

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.
