1. The long-term stability without oil lubrication. 2. particularly suitable for low-speed, reciprocating, oscillating and intermittent exercise and other working conditions; 3. Good 4. antiwear properties and chemical resistance and good corrosion resistance; 5. sleeve can be molded, flanged bushings and thrust products; 6. flexible sheet can also be used by the customer as required by lubrication cutting gaskets and other parts. Product Description: FR PTFE soft belt bearing in bronze mesh matrix, through a special sintering process, the surface rolling polytetrafluoroethylene (PTFE) and other friction reducing material filling mixture. It has a low coefficient of friction, good wear characteristics. Due to the good performance of its soft, it can be used as steel and steel for grinding isolation membrane, gap-free, no noise, no oil lubrication, maintenance-free, ideal for the purpose of non-polluting. Currently, the products have been widely used in textile machinery, bearings, automotive door hinges and other occasions.
