The composite bushing is a composite bushing made by rolling a mixture of polytetrafluoroethylene and lead rolled on the surface with steel plate as the matrix, sintered spherical bronze powder in the middle, and rolled on the surface. It has the characteristics of small friction coefficient, good wear resistance, corrosion resistance and oil-free lubrication. The use of this product can reduce costs, reduce mechanical volume, avoid shaft biting phenomenon and reduce mechanical noise. Products have been widely used in the sliding parts of various machinery, such as printing machines, lifts, textile machinery, fitness equipment, hydraulic vehicles, micromotors, solenoid valves, automobiles, motorcycles and household machinery.
