Ceramic bearing as an important foundation of the mechanical parts, has better performance, higher temperature resistance than the metal bearings, such as extra strong in the new material world dominate. In the last 10 years to national economy and the people's livelihood, in the fields of got day by day the widespread application. Aviation, maritime, nuclear industry, petroleum, chemical industry, textile industry, machinery, metallurgy, electric power, food, locomotive, subway, high speed machine tool and scientific research fields such as military technology to national defense in high temperature, high speed, cryogenic, inflammable, explosive, strong corrosion, vacuum, electric insulation, no magnetic, such special conditions dry friction work, ceramic bearing indispensable alternative role is being people gradually understanding. Along with the development of technology of processing, the level of technology increasing day by day, the cost of the ceramic bearing falling from the past, ceramic bearing has only in some high-quality precisioninstrument, small range, application field gradually extending to national economy each industry, and the product market price also gradually close to practical application, to the extent of the user can accept, so the wave of large area application of ceramic bearing have flocked to!
