A release bearing for a friction clutch, comprising:
- an inner race;
- an outer race;
- spherical rolling bodies which roll on an inner race bearing track and an outer race bearing track and are guided in a cage;
- wherein the inner race interacts with a release element for operating the friction clutch and the outer race is brought into contact in a freely rotatable manner with spring tongues of a diaphragm spring of the friction clutch;
- and
- an engine-side sealing device and a transmission-side sealing device are arranged radially between the inner race and the outer race, the engine-side sealing device has at least one sealing element with a reinforcement that engages in an annular groove of the outer race, and has a contact-free gap seal radially on the inside, the gap seal formed by a radially inwardly directed annular projection of the inner race and a pretensioned spring;
- wherein the transmission-side sealing device has a sealing element with at least A one radially oriented sealing lip and an axial sealing lip that interacts in a contactless manner with a radially outwardly directed, transmission-side end flange of the inner race.
