JFB-1 The self-lubricating flanged shaft sleeve combines the wear resistance of copper alloy (ZCuZn24Al6) and the self-lubricating performance of solid lubricant, making it maintenance free during use. The product is widely used in high load, intermittent or swinging movements, such as production lines for automobiles and locomotives, water turbines, reservoir work/accident doors, plastic machinery, etc. According to the operating conditions, various types of copper alloys can be provided.
