Abstract

There is disclosed a clutch release bearing comprising a plastic operating member having an axial sleeve and a transverse flange, and a drive or thrust member comprising a ball bearing. One of the races, here the outer, is adapted to bear against a washer bearing member through an annular holding member disposed on one side of the transverse flange. Passageways are formed in the flange to provide access for an associated actuating member to the bearing member from the other side of the flange. The holding member for the bearing member preferably comprises a washer portion, a slotted annular rim divided into segments with radially outwardly extending annular lip on the free end of the rim bearing against a transverse shoulder formed on a radially inwardly extending bead at the free end of an axial rim on the operating member. Alternatively, the annular holding member may consist of a washer, or an axially extending rim.
