Abstract: A ceramic ball bearing assembly (20) has raceway components generally held in residual compression by accompanying metal attachments. In a ceramic ball bearing assembly (20), an outer raceway (22) is formed that is held in compression by a circumscribing steel ring.

The residual compression preserves the ceramic raceway despite thermal or other stresses of operating environment. An inner ceramic raceway (24) is constructed by employing one of several of the herein described methods, and the ceramic ball bearing assembly of the present invention may use balls (26), needles, cylinders, or other rolling elements in order to achieve smooth angular translation between the inner and outer ceramic raceways.

Abstract: A ball joint includes a socket that defines an outer surface having multiple, annular, smoothly-curved teeth. A ball is received in the socket, and the socket is received in a recess of a housing. This recess defines complementarily-shaped annular, smoothly-curved teeth.
