Abstract
A release bearing for a separating clutch installed in a motor vehicle, includes a casing movable in an axial direction and operatively connected to an actuating mechanism, a non-rotatable bearing ring having a ring bottom supported by the casing; and a revolving bearing ring having a annular flange. Guided between the bearing rings is a plurality of rolling elements. An engagement disk made of a low-friction and wear-resistant material is securely fixed to the annular flange, and a spring member is operatively connected to the separating clutch and cooperates with the annular flange of the revolving bearing ring, wherein the spring member bears against the engagement disk.
