1. ) Most of the lubricant material will break up and catch fire under the high temperature, high pressure and high speed working condition. So most equipment can not use normal lubricant material to improve the durability.
2.) Therefore, carbon and graphite bearings, piston rings and sealing rings are normally used in mechanism equipments and these carbon and graphite parts can work at -200 to 200 in corrosive medium and they can normally revolve with high speed(like 100m/s) without lubricating oil.
2. About our side :
1.) We will select the most suitable graphite material for our customers according to the working conditions of the bearing
2.) The selflubricating properties of carbon graphite and graphite materials, along with stability at elevated temperatures, and resistance to most chemicals, make these materials well suited to demanding applications.
Graphite materials enable the design engineer to extend the temperature and chemical range, and with the proper adjuvant, permit the use under cryogenic conditions. Impregnation with resins and metals can be used to enhance the properties of carbon graphite.
