Brief Introduction The oilless self-lubricating bearing is a composite bearing that consists of steel backing and wear-resistant porous materials. The special wear-resistant layer is formed by sintering the copper alloy powder and graphite-based solid lubricant dispersed on a metal base at high temperature. It has gone through special oil-containing treatment. A solid lubricant is uniformly distributed inside an alloy layer, so it can form a solid lubricant film at the beginning of sliding. With low shear strength, the film can be firmly adhered to the surface of the oilless
