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.

Graphite plugs provide self-lubrication. Graphite has some unusual properties that make it an excellent lubricant. Chemically, it is one of three common allotropic forms of carbon (amorphous carbon and diamond being the other two). In contrast to diamond, which has a very dense and strong three-dimensional crystal structure, graphite has a two-dimensional crystal structure - strong in two dimensions but weak in the third. Its atoms are arranged in parallel sheets that are easily sheared off, giving graphite its characteristic slippery feeling. For example, if you were to rub a pencil lead between your fingertips, it would feel oily. That feeling is the sliding and peeling off of crystal sheets.
In the self-lubrication process, it is precisely these sheared off crystal sheets that provide the lubrication, somewhat like a piece of tissue paper between two pieces of glass. Initially there is no lubrication but as the two mating surfaces (e.g., bushing and shaft) move in relation to each other, a minute amount of graphite becomes distributed over the wear surface and acts as a solid lubricant. It will stay there a long time due to graphite’s superior stability. Although graphite sublimes at 10,000 F in a reducing atmosphere, it will oxidize in air at about 500 F, so it is important to maintain temperatures well below this threshold. In addition, graphite has a near-zero coefficient of thermal expansion. When a graphite plug is embedded into a metal part, the metal will expand but the graphite plug won't. The plug loosens, which restricts the temperature range to about 200 F if the plugs have any open surfaces (i.e., not constrained by a mating part).
