The bearing materials are generally made of plastic, carbon graphite, etc. They can work without lubricating oil or grease. The bushings have a lubricating effect on their own base. Generally, their self-lubricating effect is achieved by the solid lubricant embedded in their base, so they are also called solid lubricating bearings. In the production process of self-lubricating bushings, the burrs on their surface need to be polished, which can reduce the surface roughness of the self-lubricating bushing workpiece on the one hand, and enhance the adhesion of the coating on the other hand.
