ABSTRACT:
A clutch release bearing includes a housing, a first bearing ring having a skirt for fixed rotative securement of the first bearing ring to the housing, a revolving second bearing ring connected to the separating clutch via a spring element, and a plurality of rolling elements guided between the first and second bearing rings. Seals are provided on both sides of the rolling elements at a distance thereto and involve a sealing arrangement which is securely fixed to the housing and comprised of at least two components to establish two sealing zones for sealing an annular gap between the first and second bearing rings. The sealing arrangement cooperates with a planar surface of the revolving bearing ring and assumes a desired position, when the revolving bearing ring is installed with the assistance of a press-fit tool.
