Graphite impregnated bronze slide plate is a self-lubricating bearing plate made up of a high quality bronze with graphite filled grooves.

The bronze plate acts as the bearing surface, withstanding heavy loads, while the graphite inserts provide a solid, oil-free lubricant. The formation of lubricant forms a film of graphite between the bearing and mating surface which results in low co-efficient of friction upon the start of relative motion.
