Application Characteristics and Advantages of Partially Self-lubricating Bearings

What is self-lubricating bearing
Self-lubricating bearings are divided into composite material self-lubricating bearings, solid inset self-lubricating bearings, bimetal material self-lubricating bearings, special material self-lubricating bearings. According to different uses and working conditions, different self-lubricating bearings are selected. One big category of solid inlaid self-lubricating bearings is a kind of novel lubricating bearings with both the characteristics of metal bearings and oil-free lubricating bearings. The metal matrix bears the load, and the special formula of solid lubricating materials acts as lubrication.

Features of self-lubricating bearings
1. No oil lubrication or less oil lubrication, can be used in no maintenance or less maintenance.
2. Good wear resistance, small friction coefficient and long service life.
3. There is an appropriate amount of elastoplastic, can distribute the stress on a wider contact surface, improve the bearing capacity.
4. The static and dynamic friction coefficient is close, so as to ensure the working accuracy of the machine.
5. The machine can reduce vibration, reduce noise, prevent pollution, improve working conditions.
6. Transfer film can be formed during operation to protect the grinding shaft.
7. The hardness requirement of grinding shaft is low, thus reducing the processing difficulty of related parts.
8. Thin wall structure, light weight, can reduce the mechanical volume.
9. The back of steel can be electroplated with a variety of metals, can be used in corrosive media; It has been widely used in sliding parts of various machines.

Advantages of self-lubricating bearings
Oil-free lubrication bearing series:
1. No oil lubrication or less oil lubrication, suitable for refueling or difficult to refueling places, can be used in no maintenance or less maintenance.
2. Good wear resistance, small friction coefficient and long service life.
3. There is an appropriate amount of elastoplastic, can distribute the stress on a wider contact surface, improve the bearing capacity.
4. The static and dynamic friction coefficient is similar, which can eliminate the creep at low speed, so as to ensure the working accuracy of the machine.
5. The machine can reduce vibration, reduce noise, prevent pollution, improve working conditions.
Boundary lubricated bearing series:
1. Good bearing capacity and good wear resistance.
2. It is suitable for high load and low speed rotation movement, swing movement and often open and close frequently under the load and not easy to form hydrodynamic lubrication occasions.
3. It can be maintained without oil for a long time under boundary lubrication conditions, and the service life of the bearing can be longer if the oil is added in the overlayer.
4. The surface plastic layer can leave a certain margin when processing and forming. After assembling and pressing into the seat hole, it can be processed by itself to achieve a better assembly size.
5.The products are mainly used in automobile chassis, metallurgical machinery, mining machinery, water conservancy machinery, construction machinery, agricultural machinery, steel rolling equipment, etc.
