Definition

A machine element consisting of concentric inner and outer rings (races) and discrete rolling elements (balls or rollers) held by a cage, whose intended function is to support radial and/or axial loads while permitting relative rotation between the rings by replacing sliding contact with rolling contact to reduce friction and control relative motion.
