Because most of the lubricating oil will decompose and even catch fire at higher temperature, many equipment running at high speed, high pressure and high temperature can not use ordinary lubricating oil to improve the wear resistance of moving parts. Therefore, at present, bearings, pistons, piston rings and sealing rings made of carbon and graphite materials are used in some mechanical equipment. These parts made of carbon and graphite materials can be used in corrosive medium in the temperature range of - 200 ℃ to + 200 ℃, and can operate normally without lubricating oil at high speed (such as 100 m / s).

Excellent properties of graphite

1) Excellent self lubrication;

2) Good chemical corrosion resistance;

3) High thermal conductivity and thermal stability;

4) Sufficient mechanical strength and impact resistance;

5) Easy to machine, can be processed into a variety of geometric products.
