How About Self-lubricating Bearings?

The advantages of self-lubricating bearings (oil-free bearings), the bearings used in each machinery industry are mostly ball, rollers and so on, but a small number of self-lubricating bearings have been used, I believe that in the near future self-lubricating bearings will become the leader of the bearings.

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

Oil-free lubrication bearing series

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

Self-lubricating bearings

2.       good wear performance, small coefficient of friction, long service life.

3.       there is a moderate amount of elastic plasticity, the stress can be distributed on a wide contact surface, improve the bearing carrying capacity.

4.       static friction coefficient is similar, can eliminate the low-speed crawling, so as to ensure the accuracy of mechanical work.

5.       can make machinery to reduce vibration, reduce noise, prevent pollution, improve labor conditions.

6.       in the process of operation can form a transfer film, play a role in protecting the grinding shaft, no bite shaft phenomenon.

7.       for the hardness of the grinding shaft requirements are low, the shaft without adjustment treatment can be used, thereby reducing the processing difficulty of the relevant parts.

8.       thin-walled structure, light mass, can reduce the volume of machinery.

9.       steel back can be electroplating a variety of metals, can be used in corrosion media, has been widely used in a variety of mechanical sliding parts, such as: printing presses, textile machines, tobacco machinery, micromotors, automobiles, motorcycles and agricultural and forestry machinery and so on.

Boundary lubrication bearing series

1.       Good bearing, wear-resistant performance is good.

2.       Suitable for rotational motion, swinging motion at high load and low speed and often opening and closing frequently under load and not easy to form fluid-power lubrication.

3.       In the boundary lubrication conditions can be long-term maintenance without refueling, and refueling in the overlayer to make the bearing life longer.

4.       Surface plastic layer in the processing molding can leave a certain amount of margin, assembly pressure into the seat hole can be self-processing, in order to achieve a better assembly size.

5.       Products are mainly used in automotive chassis, metallurgical machinery, mining machinery, water conservancy machinery, construction machinery, agricultural machinery, rolling equipment.

JDB Solid Inlay Bearing Series

It is a universal base product that can be adapted to high pressure, low pressure, high temperature, low temperature, oil lubrication, oil-free lubrication or water lubrication. The product's base is high-force brass, double the hardness of the general copper sleeve, and more than double the wear resistance.

Widely used in: light industrial machinery, heavy industry machinery, construction machinery, metallurgical machinery, transport machinery, such as: casters, rolling mills, injection molding machines, paper machines, mold guide columns, ships, machine tools and so on.
