Technical principle of copper graphite bearing

The composite material used in the inlaid self-lubricating bearing is a new type of extreme pressure-resistant solid lubricating material, which is composed of a metal substrate and a solid lubricant paste embedded in the holes or grooves of the substrate. During the friction process, the metal substrate bears most of the load. After friction, the solid lubricant in the hole or groove is transferred or reversely transferred to the friction surface, forming a solid transfer film with good lubrication, firm adhesion and uniform coverage on the friction surface, which greatly reduces friction and wear. With the progress of friction, the embedded solid lubricant is continuously provided on the friction surface, which ensures the good lubrication of the friction pair during long-term operation.
