Self-lubricating bearings are now mainly divided into two series, which are divided into oil-free lubricating bearing series and boundary lubricating bearing series. What are the main characteristics and advantages of self-lubricating bearings in the process of use? Based on your understanding of self-lubricating bearings, share the following features and advantages of self-lubricating bearings.

Oil-free lubricating bearing series

1. Oil-free or low-oil lubrication, suitable for places where it is difficult to refuel 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 over a wide contact surface and improve the bearing capacity of the bearing.

4. The static and dynamic friction coefficients are similar, which can eliminate crawling at low speed, thereby ensuring the working accuracy of the machine.

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

6. During the operation, a transfer film can be formed, which protects the grinding shaft without biting the shaft.

7. The hardness requirements for grinding shafts are low, and shafts without quenching and tempering can be used, thereby reducing the difficulty of processing related parts.

8, thin-walled structure, light weight, can reduce mechanical volume.

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

Boundary lubrication bearing series

1. Good load and good wear resistance.

2.Suitable for rotary motion, swing motion under high load and low speed, and occasions where frequent opening and closing under load is not easy to form hydrodynamic lubrication.

3. Under the boundary lubrication condition, it can be maintained without oil for a long time, and the oil can be used in the layer to make the bearing life longer.

4. The surface plastic layer can leave a certain margin during processing and molding, and can be processed by itself after being pressed 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, steel rolling equipment, etc.
