Abstract
A bearing ring (10) for supporting a protective device of a rotating driveshaft is adapted to engage an annular groove of a component of the driveshaft, for example a joint yoke. The bearing ring (10) has a basic ring portion (13) which connects to a component of the protective device. The bearing ring also includes a bearing ring portion (14) which engages the annular groove. The bearing ring (10) is a composite component. The basic ring portion is produced from a different type of plastics than the bearing portion. The bearing portion (14) is produced by being injection molded around the basic ring portion (13). The bearing portion (14) is a PEEK material. Thus, the bearing portion (14) achieves a long service life while the costs of the bearing remain acceptable.
