Thrust ball bearing is composed of bearing balls supported in a ring, can be used in low thrust applications where there is little axial load. Thrust ball bearings are designed to accommodate axial/ thrust loads in one direction or double direction. They are available in ISO metric and inch series. Thrust ball bearings consist of two hardened and ground thrust plates with matching ball grooves on one side and a 1-piece brass cage that contains the precision balls. In some low-speed applications, a full complement of balls is used without the cage to increase thrust capacity. Thrust Ball Bearings are not suitable for high-speed applications. At high speeds, sliding movement between balls and raceways can occur, which may result in smearing.
