By what is the graphite copper sleeve smooth

Graphite copper bushing is used as a smooth medium to replace the traditional oil groove copper bushing by inlaying the solid smooth material with a special formula on the substrate.It can be used in the environment of not easy refueling, lack of oil for a long time or no oil, which makes up for the lack of regular refueling for the traditional copper sleeve.

Graphite copper sleeve with high strength copper alloy as the matrix (also known as JDB solid inlaid self-smoothing bearing).

Advantages of graphite copper sleeve

With high bearing capacity, impact resistance, high temperature resistance, self-smoothing ability and other characteristics, especially suitable for heavy load, low speed, reciprocating or swing and other difficult to smooth and form oil film occasions.

 

Because of its high hardness and strength, and low cost, the service life of low speed and heavy duty occasions is twice higher than that of ordinary copper sleeve, so it is favored by the majority of customers.

The working principle of graphite copper sleeve

Generally, solid smoothing agent accounts for 20-30% of the conflict surface area. The smoothing principle of graphite-copper sleeve self-smoothing bearing is that in the process of sliding conflict between the shaft and the bearing, part of the graphite particles are transferred to the conflict surface of the shaft and the bearing, forming a layer of stable solid smooth diaphragm to avoid direct adhesion and wear of the shaft and the bearing.

This rational combination combines the respective functional advantages of metal alloy and non-metal wear reduction materials, complementing each other, which not only has the high bearing capacity of metal, but also gets the smooth function of wear reduction materials.So it is especially suitable for no refueling, less refueling, high temperature, high load or water and other environments.

Graphite copper sleeve, also known as self-smoothing bearing, is a product with self-smoothing function, which is developed on the conflict surface of the copper sleeve as the metal matrix with orderly and appropriate size holes, and embedded with graphite or molybdenum disulfide as a solid smoothing agent.

At present, graphite copper sleeve has been widely used in engineering machinery, metallurgical machinery, mining machinery, locomotive bracket, steel rolling equipment, ship machinery, mold equipment, textile machinery, gas turbine and other low-speed and heavy-load, high-speed and light-load occasions.
