For oil-free self-lubricating bearings, many people do not understand, many companies still use expensive imported bearings, copper sleeves and other traditional products. In fact, self-lubricating bearings can be used to replace similar products such as copper bushings. In the machinery and automotive industries, such as the guide bushings on oil cylinders, the rotation and sliding parts of lifts, and the rotation of butterfly valves can play a role. , And the low price of such bearings can greatly reduce the company's production costs. It is believed that in the near future, oil-free self-lubricating bearings will become the leading products in the bearing industry with its unarguable advantages such as strong adaptability, wear-resistance and economy.

Oilless bearings are also called composite bearings, oilless sliding bearings, self-lubricating bearings, etc. The following are the application features and advantages of some oil-free self-lubricating bearings:

Non-oil lubricated bearing series oil-free self-lubricating bearings are known abroad. This series of products is based on high-quality low-carbon steel plate as the substrate, sintered spherical bronze powder in the middle, the surface of the mixture of rolling PTFE and lead, made of rolled bearing. Can be applied to various mechanical sliding parts, such as gear pumps, hydraulic components, pneumatic components, printing presses, textile machines, ** machines, fitness equipment, hydraulic trucks, micro-motors, automobiles, motorcycles and agro-forestry machinery.

Application features and advantages:

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, can distribute the stress on a wider contact surface, 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.

Boundary lubrication bearing series boundary lubrication bearings, said abroad. This product uses a steel plate as the base, sintered spherical bronze bronze powder as the intermediate layer, surface rolling modified polyformaldehyde and oil storage pits, and rolling bearings. The surface of the product has a plastic thickness of 0.5mm, which has good wear resistance and can work normally with less oil or oil breakage. It is suitable for working under normal temperature conditions and places with low speed and heavy load to replace the traditional copper sleeves, which not only reduces the cost but also extends the service life.

Application features:

1, bearing good, good wear resistance.
2. It is suitable for rotating motion, swinging motion under high load and low speed, and frequent opening and closing under load, which is not easy to form hydrodynamic lubrication.
3, in the boundary lubrication conditions can not long oil maintenance, and refueling in the layer to make the bearing longer life.
4. The surface plastic layer can leave a certain margin during processing and molding, and the assembly 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 and so on.

Solid-inlaid self-lubricating bearing series Solid-inlaid self-lubricating bearing series is to form appropriate and ordered holes on the metal friction surface of the bearing body, and then insert the solid lubricant with unique self-lubricating properties into the hole. And made of self-lubricating bearings. The bearing integrates the advantages of the metal matrix and specially formulated lubricating materials. It breaks through the limitations of ordinary bearings relying on oil film lubrication, and is particularly suitable for oil-free, high temperature, high load, low speed, anti-fouling, anti-corrosion, radiation protection, and It can be used in special working conditions where water or vacuum solution is immersed and no lubricating film can be added at all. The product is widely used in metallurgical rolling equipment, filling equipment, hydraulic turbines, steam turbines, instrumentation and mining equipment, marine machinery, textile machinery, shipbuilding industry, aerospace and other fields, but also applies to general engineering machinery.
