Abstract
A piston/slide shoe arrangement of a hydraulic piston machine is disclosed having a slide shoe in connection with a piston (4), with a friction reducing plastics material there between, wherein the plastics material, forming channel, extend into a through opening in the slide shoe in a direction towards a sliding contact surface of the slide shoe. The sliding contact surface in operation lies against a swash plate. The slide shoe and the plastics material are provided outside the through-opening with at least one connecting element which takes up the shear forces between the slide shoe and the plastics material.
