Composite material bearings are widely used in various fields of mechanical engineering, such as aircraft, automobiles, motorcycles, printing, textiles, etc. They mainly bear radial load. Using cold-rolled steel plate as the matrix, sintered porous bronze powder as the intermediate layer, and surface is compounded with composite modified polytetrachloroethylene self-lubricating material. The special manufacturing process and steel backed porous bronze modified PTFE multi-layer composite structure make this material have excellent comprehensive mechanical properties, wear reduction and wear resistance characteristics, and good thermal conductivity.
