The bearing is a sliding parts commonly used in machinery industry, material and metal, nonmetal, composite materials don't. Graphite bearing is with the performance requirements of mechanical equipment, carbon bearing based on metal bearings and the development of the graphite material as the main material. Graphite bearings are different from the characteristics of metal bearings, mainly in: self lubrication, high temperature resistance, corrosion resistance, light weight, etc..
Excellent properties of graphite bearings:
1, good self lubrication:
Because of its lamellar crystal structure, graphite has the property of self lubrication, and is suitable for the high temperature environment, the liquid and the unsuitable lubricant,
Especially in the absence of lubricant, the friction coefficient is lower than other materials.
2, good chemical corrosion resistance: not susceptible to acid, alkali and inorganic salts and other chemical erosion.
3, good heat resistance:
Mechanical strength and sliding characteristics will not cause any changes due to heat;
4, excellent heat shock resistance:
Compared with the low thermal expansion coefficient and good thermal conductivity of the metal material, even the sharp temperature change will not produce the crack.
5, benefit to light design:
Compared with the small volume density of the metal material, the utility model is beneficial to the light weight of the machine and reduces the sliding noise.
6, increase the use of products:
According to the specific needs of customers and the use of the environment for the deep processing of graphite bearings, increase the product in different environments, wear resistance, high temperature resistance, corrosion resistance.
Application: at present in food, beverage, textile, printing and dyeing, chemical and other industries in the conveyor bearings, centrifugal pump, submersible pump bearing, gear bearing bearings and automotive, aviation, agricultural machinery and other aspects of different degree has been applied, these parts such as grease lubricating agent will inevitably cause pollution and the graphite bearing lubrication is very strong, and can run on without the use of lubricating oil.
