Zusammenfassung:	A piston pin bushing is described which has a sufficient lifespan at higher piston pressures. The piston pin bushing has in each transition region a perforation. The area of material reduction is limited to at least one transition region between the apex lines. The bushing material in this transition region is at least so reduced that in the inserted position a portion of the radial pressure of the piston pin bushing in the area of the apex lines is shifted from the middle to the area of both bushing ends.
