Technical Principles of 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.

Technical principle of self - lubricating bearings
The composite material used in the inlaid self-lubricating bearing is a new type of extreme pressure resistant solid lubrication material, which is composed of a metal substrate and a solid lubricant paste embedded in the hole or groove of the substrate. It has high bearing capacity, impact resistance, high temperature resistance, strong self-lubricating ability and other characteristics, especially suitable for heavy load, low speed, reciprocating or swing and other difficult to lubricate and form oil film occasions, also not afraid of water and other acid erosion and erosion. The products have been widely used in metallurgical continuous casting machine, steel rolling equipment, mining machinery, die, hoisting machinery, textile machinery, wind power generation, ship, steam turbine, water turbine, injection molding machine and equipment production line. The wear resistance is twice that of ordinary bushing.
The metal substrate bears most of the load during the friction process. After friction, solid lubricants in holes or grooves transfer or reverse transfer to the friction surface, forming solid transfer film with good lubrication, firm adhesion and uniform cover on the friction surface, which greatly reduces friction and wear. As the friction progresses, the embedded solid lubricant is continuously provided on the friction surface to ensure the good lubrication of the friction pair during long-term operation.

The price of self-lubricating bearings
