Abstract

In a hydraulic clamping element for axially clamping a machine part (23) in place on a shaft (22) against a fixed stop, comprising an annular housing (1), at least one pressure chamber (7) running in the housing, a pressure screw (8) which can be screwed into the pressure chamber, and an annular pressure space (16) which is connected to the pressure chamber and is likewise formed in the housing and in which an axially displaceable clamping piece engages by means of an annular piston (19), for space-saving reasons the axis of the pressure chamber (7) is a secant separate from the ring diameter of the housing. <IMAGE>
