Customized self-lubricating bronze Graphite copper bushing
1. Good load bearing and wear resistance;
2. It is suitable for high load and low speed rotating motion, swinging motion and frequent opening and closing under load, which is not easy to form hydrodynamic lubrication;
3. Under the condition of boundary lubrication, the bearing can be maintained without oil for a long time, and the service life of the bearing is longer when oil is added in the layer;
4. The surface plastic layer can leave a certain margin during processing and forming, and can be processed by itself after assembly and pressing into the seat hole, so as to achieve better assembly size.
