Many people do not know about oil-free self-lubricating bearings. Many companies still use traditional products such as expensive imported bearings and copper sleeves. In fact, self-lubricating bearings can completely replace copper sleeves and other similar products. In the machinery and automobile industries, such as the guide sleeve on the oil cylinder, the rotation and sliding parts of the elevator, the rotation on the butterfly valve, etc., can play a good role. And the low price of such bearings can greatly reduce the production cost of enterprises. It is believed that in the near future, oil-free self-lubricating bearings will become the leading products in the bearing industry due to their indisputable advantages such as strong adaptability, wear resistance and economy.

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

Oil-free bearing series

Oil-free self-lubricating bearings are called abroad. This series of products is a rolling bearing made of high-quality low-carbon steel plate as the matrix, sintered spherical bronze powder in the middle, and a mixture of PTFE and lead rolled on the surface. It can be applied to the sliding parts of various machinery, such as gear pumps, hydraulic components, pneumatic components, printing machines, textile machines, tobacco machines, exercise machines, hydraulic pallets, micro motors, automobiles, motorcycles, and agricultural and forestry machinery.

Application features and advantages:

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

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

3. There is an appropriate amount of elastoplasticity, which can distribute the stress on a wider 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 speeds, thereby ensuring the working accuracy of the machine.

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

6. A transfer film can be formed during operation, which can protect the grinding shaft without the phenomenon of shaft biting.

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

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

9. The back of the steel can be electroplated with a variety of metals, which can be used in corrosive media.

Boundary Lubrication Bearing Series

Boundary lubrication bearing, called abroad. The product is a sliding bearing made of steel plate as the base body, sintered spherical tin bronze powder as the intermediate layer, surface rolling modified polyoxymethylene and oil storage pit. The surface of the product has a plastic thickness of 0.5mm, which has good wear resistance, and can work normally under the conditions of low oil or gap-cut oil. It is suitable for working under normal temperature conditions and low-speed heavy-duty places to replace traditional copper sleeves, reducing costs and extending service life.

Application features:

1. Good load bearing and good wear resistance.

2. It is suitable for rotating motion, rocking motion under high load and low speed, and occasions where hydrodynamic lubrication is not easy to form due to frequent opening and closing under load.

3. It can be maintained without oil for a long time under boundary lubrication conditions,

And adding oil in the over layer makes the bearing life longer.

4. A certain margin can be left for the surface plastic layer during processing and molding, and it can be processed by itself after assembling and pressing 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.

Solid inlaid self-lubricating bearing series

The solid-inlaid self-lubricating bearing series are self-lubricating bearings made by opening holes of appropriate size and orderly arrangement on the metal friction surface of the bearing matrix, and then embedding molded solid lubricants with unique self-lubricating properties in the holes. . The bearing combines the respective advantages of metal matrix and specially formulated lubricating materials, breaking through the limitations of ordinary bearings relying on oil film lubrication, and is especially suitable for oil-free, high temperature, high load, low speed, anti-fouling, anti-corrosion, anti-radiation, and It is used under special working conditions where it is soaked in water or vacuum solution and cannot add lubricant film at all. This product is widely used in metallurgical steel rolling equipment, filling equipment, water turbines, steam turbines, instruments and meters, mining equipment, marine machinery, textile machinery, shipbuilding industry, aerospace and navigation and other fields, and it is also suitable for general engineering machinery.
