It is a mixture of polytetrafluoroethylene (PTFE) and other antifriction materials on the surface of bronze wire. The product has low friction coefficient and good wear resistance, and can work stably for a long time without oil lubrication.
The utility model is especially suitable for low speed, reciprocating motion, swing and intermittent motion. The utility model is characterized in that the utility model has the advantages of good flexibility, and the utility model can be processed into a thin wall bearing which is used as a separating film for steel and steel grinding, and the utility model has the advantages of no clearance, no maintenance, no pollution, no noise and no oil lubrication. Products have been widely used in car door hinge, automotive control rod, shock absorber piston ring, textile machinery, food filling equipment, instrumentation and other occasions.
