Characteristics And Advantages Of Self-lubricating Bearings

Self-lubricating bearings are now mainly divided into two series, oil-free lubricated bearing series and boundary lubricated bearing series. So what are the main characteristics and advantages of self-lubricating bearings during use?

Oil-free lubrication bearing series

1. Oil-free lubrication or less oil lubrication is suitable for places where oil cannot be added or it is difficult to add oil. It can be used without maintenance or with less maintenance.
2. Good wear resistance, small friction coefficient and long service life.
3. It has a moderate amount of elasticity and plasticity, which can distribute stress on a wider contact surface and improve the bearing capacity of the bearing.
4. The static and dynamic friction coefficients are similar, which can eliminate creeping at low speed, thereby ensuring the working accuracy of the machine.
5. It can reduce vibration, reduce noise, prevent pollution and improve working conditions.
6. During operation, a transfer film can be formed to protect the grinding shaft without biting the shaft.
7. The hardness requirement for the grinding shaft is low, and the shaft that has not been quenched and tempered can be used, thereby reducing the processing difficulty of related parts.
8. Thin-walled structure and light weight can reduce the size of the machine.
9. The back of the steel can be electroplated with a variety of metals and can be used in corrosive media; it has been widely used in the sliding parts of various machines, such as printing machines, textile machines, tobacco machinery, micromotors, automobiles, motorcycles, agricultural and forestry machinery, etc.

Boundary lubrication bearing series

1. Good load-bearing and good wear resistance.
2. Suitable for rotational movement and swinging movement under high load and low speed, and occasions where frequent opening and closing under load are not easy to form fluid dynamic lubrication.
3. Under boundary lubrication conditions, it can be maintained for a long time without oiling, and oiling in the overlayer can make the bearing service life longer.
4. A certain margin can be left when the surface plastic layer is processed and formed, and it can be processed by itself after assembly and pressing into the seat hole 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, rolling equipment, etc.
