The advantages of self-lubricating bearings (oil-free bearings), most of the bearings used in various machinery industries are ball bearings, needle rolls and so on, but a small part of the use of self-lubricating bearings, I believe that in the near future will come from lubricating bearings will become the dominant bearings.

The following are the application characteristics and advantages of partially self-lubricating bearings:

Oil free lubricated bearing series

Self-lubricating bearing

Self-lubricating bearing

1, no oil lubrication or less oil lubrication, suitable for refueling or difficult to refueling places, can be used without maintenance or less maintenance.

2, good wear resistance, small friction coefficient, long service life.

3. With the right amount of elastoplastic, the stress can be distributed on a wider contact surface and the bearing capacity can be improved.

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

5, can make the machine reduce vibration, reduce noise, prevent pollution, improve working conditions.

6, in the process of operation can form a transfer film, play a protective role on the grinding shaft, no shaft biting phenomenon.

7, for grinding shaft hardness requirements are low, without quenching and tempering treatment of the shaft can be used, so as to reduce the processing difficulty of the relevant 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 machinery, such as printing press, textile machine, tobacco machinery, micromotor, automobile, motorcycle and agricultural and forestry machinery, etc.

Boundary lubricated bearing series

1. Good bearing capacity, good wear resistance.

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

3. In the condition of boundary lubrication, it can be long-term without refueling and maintenance, while refueling in the layer makes the bearing longer service life.

4. The plastic layer on the surface can leave a certain allowance when processing and forming, and can be processed by itself after assembling and pressing into the seat hole, so as to achieve 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.

JDB solid inlaid bearing series

General basic products, whether high pressure, low pressure, high temperature, low temperature, oil lubrication, oil free lubrication or water lubrication, can be adapted. The base of the product is high force brass, which is twice as hard as the general copper sleeve and more than twice as wear-resistant.

Widely used in: light industry machinery, heavy industry machinery, construction machinery, metallurgical machinery, conveying machinery, such as: continuous casting machine, rolling mill, injection molding machine, paper machine, mold guide post, ships, machine tools and so on
