Ceramic bearing

As an important mechanical basic part, ceramic bearings are unique in the world of new materials because of their excellent performance unmatched by metal bearings, high temperature resistance, and super strength. In the past ten years, it has been increasingly used in various fields of national economy and people's livelihood. First, because ceramics are almost not afraid of corrosion, ceramic rolling bearings are suitable for operation under harsh conditions covered with corrosive media. Second, because the density of ceramic rolling balls is lower than steel and much lighter, the centrifugal effect of the outer ring during rotation can be reduced by 40%, and the service life is greatly extended. Third, ceramics are less affected by thermal expansion and contraction than steel, so when the clearance of the bearing is fixed, the bearing can be allowed to work in an environment where the temperature difference changes more drastically. Fourth, because the modulus of elasticity of ceramics is higher than that of steel, it is not easy to deform when stressed, so it is helpful to increase the working speed and achieve higher accuracy
