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.
