Ball bearings or point contact bearings are among the most common types of rolling bearings. the purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. they are characterized by low friction and can withstand higher speeds than roller bearings of the same size. ball bearings can be loaded by radial load, axial load, torque or in combination, depending on the type.

Ball bearings, available in both inch and metric sizes, meet virtually all precision requirements including thin section bearing，deep groove ball, angular contact ball, self-aligning ball, thrust ball, angular contact thrust ball, insert ball and full ball complement.
