A clutch release bearing includes a housing, a first bearing ring having a skirt for fixed rotative securement of the 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, wherein one seal is configured to seal an annular gap between the first and second bearing rings and includes a sealing arrangement which is securely fixed to the first bearing ring and comprised of at least two components to establish two sealing zones, wherein the second bearing ring and the sealing arrangement interact in such a way that a desired installation position of the sealing arrangement is automatically establishes as the second bearing ring is installed.
