1，Because ceramic almost afraid of corrosion, so the ceramic rolling bearing is suitable for the corrosive fluids in bad condition。

　　2，Due to the density of ceramic rolling ball is lower than steel, more much lighter weight, so the external ring spinning the centrifugal effect can reduce 40%, thus greatly extend the service life。

　　3，Ceramic is affected by heat bilges cold shrink is smaller than steel, therefore, when bearing clearance must be allowed bearing in more severe working environment temperature change。

　　4，Due to the elastic modulus of the ceramic is higher than steel, when the stress is not easy to deformation, thus to improve work speed, and achieve higher precision。
