Abstract

The invention relates to a piston-cylinder arrangement, in particular a slave cylinder for a hydraulic clutch actuating device, comprising a cylinder housing which is made of a plastic, in which an annular pressure chamber is formed in which a piston is mounted so as to be axially movable for actuation of a clutch release bearing, wherein the inner wall of the pressure chamber forms a guide sleeve. In the case of a piston-cylinder arrangement which stands up to the pressures and temperatures that occur in operation of the clutch actuating device, a stop is situated on the guide sleeve facing the clutch release bearing, the stop being in the form of a threaded connection.
