What is the principle of self-lubricating bearings?

At present, most of the bearings used in various mechanical industries are balls, needles and the like. Only a small part of them have adopted self-lubricating bearings. It is believed that in the near future, lubricating bearings will be indisputably adaptable, wearable and economical. Advantages have become the leading product in the bearing industry. The following are the application features and advantages of some self-lubricating bearings:

Oil-free lubrication bearing series:

1, no oil lubrication or less oil lubrication, suitable for places can not refuel or difficult to refuel, can be used without maintenance or less maintenance.

2, good wear resistance, low friction coefficient, long service life. 3, there is a moderate amount of elastoplasticity, which can distribute the stress on a wider contact surface and improve the bearing capacity.

4, static and dynamic friction coefficient is similar, can eliminate the creep at low speed, thus guarantee the working precision of the machinery.

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

6, in the course of operation can form a transfer film, play a role in the protection of the grinding axis, no bite axis phenomenon.

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

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

9, the back of the steel 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 and many more.
