Ceramics are hardly corrosive, so ceramic rolling bearings are suitable for operation under harsh conditions filled with corrosive media.
The density of ceramic rolling balls is lower than that of steel, and the weight is much lighter. Therefore, the centrifugal effect of the outer ring can be reduced by 40% when rotating, and the service life is greatly extended.
Ceramics are less affected by thermal expansion and contraction than steel. Therefore, when the clearance of the bearing is constant, the bearing can be allowed to work in an environment where the temperature difference changes drastically.
The modulus of elasticity of ceramics is higher than that of steel, and it is not easily deformed when subjected to force, so it is beneficial to increase the working speed and achieve higher precision.
