Abstract
A clutch thrust bearing device includes a rolling bearing having a fixed ring, a rotatable ring, and a plurality of rolling elements between the rings; an axially movable piston disposed between a housing and the rolling bearing and having a radial plate pressing against an axial contact surface of the fixed ring; at least one resilient seal member sealing the piston relative to the housing; and a resilient body exerting an axial preload onto an axial contact surface of the rotatable ring. The rolling bearing is axially movable by the piston to compress the resilient body. A resilient sleeve is mounted to the fixed ring and has at least one sealing lip in sliding contact with the rotatable ring.
