Oil Free Self-Lubricating Wear-Resistant JDB Graphite Copper Bearing
1.No oil lubrication or less oil lubrication, suitable for places where oil can not be added or it is very difficult to add oil. It can be used without maintenance or less maintenance.
2. Good wear resistance, small friction coefficient and long service life. 3. It can distribute the stress on a wide contact surface and improve the bearing capacity.
4. The static and dynamic friction coefficients are similar, which can eliminate the creeping at low speed and ensure the working accuracy of the machine.
5. It can reduce vibration, noise, pollution and improve working conditions.
6. 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.
7. The hardness of the grinding shaft is low, and the shaft without quenching and tempering treatment can be used, thus reducing the machining difficulty of related parts.
8. Thin wall structure, light weight, can reduce the mechanical volume.
9. The back of steel can be electroplated with many kinds of metals, which can be used in corrosive media. At present, it has been widely used in the sliding parts of various machines, such as printing machines, textile machines, tobacco machines, micro motors, automobiles, motorcycles, agricultural and forestry machines, etc
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. Strict casting processing control, make the tolerance less than 0.003m
5. Long working life and PRsmooth surface treatme
Strict quality control
We make promise every production manufactured is strictly follow technical standard, high wear resistance, high corrosion
resistance, durable and stable perfomance.
