Ceramic almost afraid of corrosion, ceramic rolling bearings are suitable for operating under harsh conditions covered with corrosive media.

Second, due to the the ceramic rolling ball lower density than steel, the weight but also to much lighter, so the centrifugal effect of the rotation of the outer ring can be reduced by 40%, thus greatly extend the life.

Third, ceramics by thermal expansion and contraction smaller than that of steel, therefore the bearing clearance is constant, you can allow the bearing to work in a more dramatic temperature changes.
Fourth, since the ceramic of high modulus of elasticity than steel, when the force is not easy to deformation, and thus help to improve the working speed, and to achieve higher precision.

In summary, because so many advantages of ceramic bearings in applications, major imports bearing manufacturers, such as: SKF bearings, NSK Bearings, FAG bearings are involved in this field and launch products.
