| JDB solid embedded self-lubricating bearing
|
    
|
| |
| Basic characteristics |
|
| JDB solid embedded self-lubricating bearings combine the wear resistance of copper alloy (ZCuZn24Al6) with the self-lubricating properties of solid lubricants, making them maintenance free during use. The product is widely used for high load, intermittent or swinging motion, such as automobile and locomotive production lines, water turbines, reservoir work/accident doors, plastic machinery, etc. According to the operating conditions, various types of copper alloys can be provided. |
