Abstract: A crosshead bearing is disclosed, in particular for stroke piston machines, including a bearing surface (1) that contains multiple oilways (2), each of which is connected through a rearward borehole (3) to a lubricant source. The goal of the invention is to lower the peak oil pressure at the central load positions (4a, 4b) of the crosshead bearing and thereby achieve an overall load increase. This is achieved according to the invention by having one oilway (2) at each of the opposing central load positions (4a, 4b) of the bearing surface (1) be designated as the main discharge oilway (5).

Abstract: A piston compressor with at least one compression cylinder having a piston, and with one suction port and one pressure port is described. The suction port and the pressure port are arranged at one end face of the compression cylinder.
