Abstract: A compressor for an air conditioning system comprises a piston and a pin. The piston comprises an aperture forming a piston bearing surface and a lubrication port in communication with the aperture. The pin comprises a pin bearing surface and the pin is received within the aperture to form an interface between the pin bearing surface and the piston bearing surface. In another embodiment, a method of lubricating within a compressor comprises rotating a crankshaft within a crankcase, introducing lubricant into the crankcase; and contacting the lubricant with a portion of a pin disposed within a piston via a lubrication port in the piston. In yet another embodiment, a piston for a compressor comprises an aperture forming a piston bearing surface and a lubrication port in communication with the aperture.
