Embedded self-lubricating bearings are mainly used in bridges, rollers, furnace machinery, underwater equipment, petroleum machinery, metallurgical equipment, lifting and transportation machinery, etc. They mainly bear radial load. Based on metal alloys, solid lubricants are embedded on their working surfaces to release and generate a solid lubrication film on the sliding surface during the working process, separating the worn parts and achieving the purpose of reducing friction and wear. According to different applications, embedded bearings can use high-strength brass alloys, bronze alloys, cast iron, and bimetallic materials as the matrix. Self-lubricating embedded bearings combine the characteristics of metal and non-metal, and have advantages of high load-bearing capacity, small friction coefficient, good wear resistance, and long service life.
