First, because the ceramic is almost afraid of corrosion, so full of ceramic rolling bearings in the corrosive medium suitable for the harsh operating conditions.
Second, the density of ceramic ball rolling lower than steel, air conditioning clutch bearing lighter weight, much more, so rotating the external ring of the centrifugal effect can be reduced by 40%, thus greatly extending service life.
Third, the ceramic by thermal expansion and contraction of smaller than steel, Low-noise bearings so when the bearing clearance must be allowed to change in bearing temperature is more severe in the environment.
Fourth, as the ceramic high elastic modulus of steel,Evaluation of Low-Noise the force is not easy deformation, it will help improve the speed of work and achieve high accuracy.
