Sealed clutch thrust bearing device and driveline system including such a device

A clutch thrust bearing device comprising:

• a rolling bearing having a fixed ring, a rotatable ring, and a plurality of rolling elements located in a raceway chamber defined between the rings;
• an axially movable piston disposed between a housing and the rolling bearing, the axially movable piston 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 forming a piston cavity, the piston cavity being connectable to a source of hydraulic fluid for providing a variable fluid pressure to the cavity to move the piston axially;
• a resilient body exerting an axial preload onto an axial contact surface of the rotatable ring, the rolling bearing being axially movable by the piston to compress the resilient body;
• and
• a resilient sleeve mounted to the fixed ring, the resilient sleeve comprising at least one sealing lip in sliding contact with the rotatable ring,
• wherein the resilient seal member includes a radial protrusion configured to limit axially movement of the resilient sleeve relative to the piston.
