Product features：
The ceramic rolling bearing is suitable to work in harsh condition of corrosive fluids, because ceramic is almost not afraid of corrosion.
Due to the lower density of ceramic rolling balls and much lighter weight than steel, the centrifugal effect to external race can be reduced by 40% when rotating, thus greatly extend the service life.
The ceramic is less affected by thermal expansion than steel, therefore, when bearing clearance is certain, it can work in a environment where temperature changes more severely.
The elastic modulus of ceramic is higher than steel, so ceramic is not easy to deform under stress, which can improve work speed, and achieve a higher precision.
Widely used for medical apparatus and instruments, cryogenic engineering, optical instrument, high-speed machines, high-speed electric machinery, printing machinery, food processing machinery, aviation, spaceflight, navigation, petroleum, chemical industry, automobile, electronics, metallurgy, electric power, textile, pumps.
