Skf Ceramic Ball Bearing 689

Since ceramics are hardly corrosive, ceramic rolling bearings are suitable for covering corrosive media. Work under harsh conditions. Since the density of ceramic rolling balls is lower than that of steel, the weight is much lighter, so when rotating, the outer ring Centrifugation can be reduced by 40%, and the service life is greatly extended.

Third, the influence of the heat shrinkage of the ceramics is smaller than that of the 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 more severely.

Fourth, since the modulus of elasticity of ceramics is higher than that of steel, it is not easily deformed when subjected to force, so it is beneficial to increase the working speed.

And achieve higher precision.
