1. No oil lubrication or less oil lubrication. It is suitable for places that cannot be refueled or difficult to refuel. It can be used without maintenance or less maintenance.

2. Good wear resistance, small friction coefficient and long service life.

3. There is an appropriate amount of elastoplasticity, which can distribute the stress on the wider contact surface and improve the bearing capacity of the bearing.

4. The static friction coefficient is similar, which can eliminate the creep at low speed, thus ensuring the working precision of the machine.

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

6. The transfer film can be formed during the operation to protect the grinding shaft without biting.

7. The hardness requirement of the grinding shaft is low, and the shaft without the quenching and tempering can be used, thereby reducing the processing difficulty of the related parts.

8, thin wall structure, light weight, can reduce the mechanical volume.

9, steel back can be plated with a variety of metals, can be used in corrosive media; has been widely used in various mechanical sliding parts, such as: printing presses, textile machines, tobacco machinery, micro-motors, automobiles, motorcycles and agricultural and forestry machinery, etc. Wait.
