Abstract

A piston arrangement for a hydraulic piston machine is disclosed, with a piston (2) and with a sliding block (4) which is produced from a plastic material, wherein a piston foot (10) and a joint socket (12) arranged on the sliding block (4) form a joint, and the piston foot (10) has a tapered portion (14) engaged from behind by a collar (16) of the joint socket (12). According to the invention, the collar (16) is caulked here towards the tapered portion (14). Furthermore, a manufacturing method for manufacturing the piston arrangement is disclosed.
