Application Characteristics And Advantages Of Self Lubricating Bearings
Sep 13, 2018

At present, most of the oil-free bearings used in various mechanical industries are still balls, needles and so on, but a small number of self-lubricating bearings have been used, it is believed that in the near future from lubricating bearings will become the dominant bearings.


The following are the characteristics and advantages of some self lubricating bearings.

Oil-free bearing series

1. No oil lubrication or less oil lubrication, suitable for places where it is impossible to refuel or difficult to refuel, can be used without maintenance or less maintenance.

2, good wear resistance, low friction coefficient and long service life.

3. Proper elastoplasticity can distribute stress on a wide contact surface and improve bearing capacity.

4, static and dynamic friction coefficient is similar, can eliminate crawling at low speed, so as to ensure the accuracy of mechanical work.

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

6, in the process of operation, the transfer film can be formed to protect the grinding shaft without biting the shaft.

7. The hardness requirement of the grinding shaft is low, and the unquenched and tempered shaft can be used, thus reducing the processing difficulty of the related parts.

8, thin-walled structure, light weight, can reduce the volume of machinery.

9. Steel back can be electroplated with a variety of metals, can be used in corrosive media; has been widely used in various mechanical sliding parts, such as: printing press, textile machinery, tobacco machinery, micro-motor, automobiles, motorcycles and agricultural and forestry machinery and so on.
