First, since the ceramic almost afraid of corrosion, so that the ceramic rolling bearing suitable for operation under harsh conditions covered corrosive medium. <br>Second, since the ceramic ball rolling lower density than steel, much lighter weight and more, and therefore the centrifugal effect of the rotation of the outer ring can be reduced by 40%, and thus greatly extend the service life. <br>Third, the ceramic thermal expansion and contraction of the affected less than steel, and therefore the clearance of the bearing is constant, the bearing can be allowed to operate in more severe temperature changes in the environment. <br>Fourth, due to the high modulus of elasticity than steel, ceramic, not easily deformed under stress, thus help to improve the speed, and achieve high accuracy.
