The invention relates to a hydraulic expansion chuck comprising a main body (1) that extends along a rotational or longitudinal central axis (2) and is composed of a shaft part (20), for directly or indirectly coupling the hydraulic expansion chuck to a module of a modular tool system or to a machine spindle, and a clamping part (30), joined to the shaft part in a rotationally and axially fixed manner for receiving and clamping a shank tool. The shaft part comprises a receiving socket which extends towards the clamping part and has a central socket-opening in which a connection pin (31) of the clamping part, which pin extends towards the shaft part, is form-fittingly received. According to the invention, the clamping part comprises a stop which is radially offset from the connection pin and axially strikes the receiving socket.
A hydraulic expansion chuck comprising a base body, which extends along a rotational or longitudinal central axis and which is comprised of a shaft part for the direct or indirect coupling of the hydraulic expansion chuck to a module of a modular tool system or to a machine spindle, and a clamping part, which is joined to the shaft part in a rotationally and axially fixed manner, for receiving and clamping a shaft tool, wherein the shaft part has a receiving sleeve extending towards the clamping part comprising a central sleeve opening, in which a connecting pin of the clamping part, which extends towards the shaft part, is received in a positive manner,
