摘要

Joined to a rotating ring (RR) (10), a plastic thrust ring (30) has a positioning section (PS) (31) and a centering section (CS) (33). The PS makes contact with the RR's front side and can make contact with a diaphragm spring. The CS has an inner surface to make contact with the RR's outer seating and to take care of a coaxial position for the RR and a plastic thrust ring.
