PCT No. PCT/DK95/00272 Sec. 371 Date Dec. 26, 1996 Sec. 102(e) Date Dec. 26, 1996 PCT Filed Jun. 28, 1995 PCT Pub. No. WO96/02752 PCT Pub. Date Feb. 1, 1996A hydraulic piston machine is disclosed, having a piston arranged to move back and forth in a cylinder body. In such a machine it is desirable to be able to achieve a longer service life, even when the hydraulic medium is not suitable for lubricating the bearing faces. For that purpose, at least on its outer face sliding on the cylinder body, the piston has a layer of a friction-reducing plastics material, wherein at the end of the piston there is provided a bearing face of an articulated joint by means of which a slide shoe is connected, articulated to the piston, the layer being continued onto the bearing face.
