First, because of the ceramic is almost afraid of corrosion, so the ceramic rolling bearings suitable for operating in harsh conditions covered with corrosive media.

Second, because the density of the ceramic rolling the ball lower than steel and much lighter weight but also rotates the centrifugal effect of the external ring can be reduced by40%, thus greatly extended service life.

Third, the ceramic thermal expansion and contraction than steel, and thus allows the bearing when the bearing clearance, more dramatic changes in temperature environment.

Fourth, because of the high elastic modulus of ceramic steel, the force is not easy to deformation, and therefore it help to improve the pace of work, and achieve high accuracy.
