Abstract

A piston assembly for a hydraulic piston motor is disclosed, having a piston and having a sliding pad, wherein the piston is connected to the sliding pad via a joint which has an articulation socket and an articulation head, wherein the articulation head has a tapered portion which is engaged behind by a collar of the articulation socket. Here, the part with the articulation head is manufactured from a plastic, in particular from a thermosetting plastic. A piston assembly for a hydraulic piston motor is also disclosed, having a piston and having a sliding pad, wherein the piston is connected to the sliding pad via a joint which has an articulation socket and an articulation head, wherein the articulation head has a tapered portion which is engaged behind by a collar of the articulation socket. Here, the part with the articulation socket is manufactured from a thermosetting plastic. Furthermore, a method is disclosed for manufacturing the piston assembly in a near-end-shape manner.
