JDB JGB Graphite Bronze Guide Bushing Solid Lubricant Long Working Life

Product description

Copper graphite bearing is a self-lubricating bearing made of special materials. According to different uses and working conditions, different copper graphite bearings are selected. One of the large-scale solid inlaid copper graphite bearings (JDB) is a new type of lubricating bearing which has the characteristics of both metal bearing and oil-free bearing. It is loaded by metal matrix and lubricated by special solid lubricating materials.

product feature

It has the characteristics of high bearing capacity, impact resistance, high temperature resistance, and strong self-lubricating ability. It is especially suitable for heavy load, low speed, reciprocating or swing and other occasions where it is difficult to lubricate and form oil film, and it is not afraid of water erosion and other acid erosion. At present, the products have been widely used in metallurgical continuous casting machine, rolling equipment, mining machinery, ships, steam turbines, water turbines, injection molding machines and equipment production lines.

The advantages of graphite copper sleeve bearing are:
1. Good bearing capacity 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, it can be maintained without oil for a long time, but the oil in the layer makes the service life of the bearing longer;
4. When the surface plastic layer is processed and formed, a certain margin can be reserved, and it can be processed by itself after assembly and pressing into the seat hole, so as to achieve better assembly size

5. It can distribute the stress on a wide contact surface and improve the bearing capacity.

6. The static and dynamic friction coefficients are similar, which can eliminate the creeping at low speed and ensure the working accuracy of the machine.

7. It can reduce vibration, noise, pollution and improve working conditions.

8. In the process of operation, it can form a transfer film, which plays a role in protecting the grinding shaft and has no shaft biting phenomenon.

9. The hardness requirement of the grinding shaft is low, and the shaft without quenching and tempering treatment can be used, thus reducing the machining difficulty of relevant parts.
