A clutch actuator () for actuating a vehicle clutch includes a cylinder () filled with pressure medium. An annular piston () is axially displaceably arranged in the cylinder. The annular piston () is fixedly operatively connected to a sliding sleeve () slidably mounted on a guide sleeve (). A radially inner casing surface () of the annular piston () has an inner radius (Ri) and is arranged radially next to the guide sleeve (). A sliding ring () supports the sliding sleeve () on the guide sleeve (). The sliding ring () is inserted into a groove () in the radially inner casing surface (). In order to be able to mount undivided sliding rings, the groove () has a single radially extending groove wall () and is open toward an axially outer or inner end face () of the annular piston ().
