Firstly, because ceramics are hardly afraid of corrosion, ceramic rolling bearings are suitable for working in harsh conditions with corrosive media.
Secondly, because the density of ceramic balls is lower than that of steel, and the weight is much lighter, the centrifugal effect on the outer ring can be reduced by 40% when rotating, thereby prolonging the service life greatly.
Thirdly, ceramics are less affected by thermal expansion and cold contraction than steel, so the bearing can be allowed to work in the environment where the temperature difference varies sharply when the clearance of the bearing is fixed.
Fourthly, because the elastic modulus of ceramics is higher than that of steel, it is not easy to deform under stress, so it is helpful to improve the working speed and achieve higher precision.
Major use editor

Ceramic bearings have the characteristics of high temperature resistance, cold resistance, wear resistance, corrosion resistance, magnetoelectric insulation, oil-free self-lubrication, high speed and so on. It can be widely used in the fields of aviation, aerospace, navigation, petroleum, chemical industry, automobile, electronic equipment, metallurgy, electric power, textile, pumps, medical devices, scientific research and defense and military affairs. It is a high-tech product of new materials.
