Clutch thrust bearing with dust=proof seals to prevent ingress of abrasive particles

摘要

The clutch thrust bearing consist of a series of rollers (3), a turning sleeve (5), and a fixed sleeve (1). A seal (12) is made up, in one part, of an annular seal (14) provided in one part with a toe (14a) and a lip (14b). The seal is made up, in the other part, of a annular support (13) mounted on one of the turning sleeves. The annular support (13) encloses the part forming the toe. It presents a deformable portion capable of being pressed onto and maintained by clamping onto one of the turning sleeves. It is designed to maintain by clamping the annular joint (14).
