A mechanical seal for providing a seal around the drive shaft of a variable displacement swash plate type compressor used in an air conditioning system for a vehicle comprising a rotating bearing surface, an associated stationary bearing surface and a lubricant embedded in the stationary bearing surface. During operation of the compressor, the rotating bearing surface is caused to move against the stationary bearing surface causing lubricant to be released between the bearing surfaces, thereby providing efficient lubrication of the bearing surfaces.
