Graphite bearings to graphite materials as the main substrate, radial compressive strength is relatively low, usually used in medium and low load conditions.
In order to improve the mechanical strength of graphite bearings, in particular, graphite inlaid lubrication bearings in order to improve its impact toughness, commonly used in some wear resistance of the fusible metal impregnated copper alloy lining, but in the larger load conditions, often Still do not meet the required mechanical strength, so people began to use powder metallurgy copper-based solid inlaid lubrication bearing gold manufacturing bronze graphite oil bearing. With the bearing load requirements to further improve the bronze graphite oil bearing is difficult to meet the requirements, then people have developed a mosaic graphite bearings.
Inlaid graphite bearing manufacturing is based on metal materials, graphite as a solid lubricating material embedded in the friction surface of the bearing metal substrate, for the bearing working conditions of the lubricating material. The compressive strength, bending strength, thermal expansion coefficient generally depends on the matrix metal material, can be run under heavy load.
