JDB-650 Copper based solid embedded self-lubricating bearings

JDB-650 Copper based solid embedded self-lubricating bearings

Basic characteristics

JDB-650 Copper based solid embedded self-lubricating bearings combine the wear resistance of copper alloy (ZCuZn24Al6) and the self-lubricating performance of solid lubricants, making them free of oil maintenance 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.
