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.

Specifications
Si3N4 ZrO2 Material ball 6805 6806 2rs hybrid ceramic ball bearing
1.Material:Chrome steel,stainless steel
2.Clearance:C2 C0 C3 C4 C5
3.Tolerance:ABEC1(P0) ABEC3(P6)
Advantages
1, high speed: the relative sliding, wear and heat greatly reduce oil mist lubrication up to 3.5 million DN greased up to 1.2 million DN
2, long life: life ceramic bearings in proper working environment is all-steel bearings 3-5 times.
3: even if the lubrication conditions are very poor or no lubrication state, unique ceramic bearings self-lubricating function can ensure the bearing normal work, self-lubricating.
4, corrosion resistance: ceramic bearing has excellent corrosion resistance and can operate normally under corrosive conditions.
5, high rigidity: the elastic modulus ratio of the ceramic material bearing steel of approximately 50%, thus greatly improving therigidity of the bearing.
6, wear-resistant: ceramic material hardness up to HV1700, greatly improve the wear resistance of the bearing.
7, light weight: ceramic material lighter than steel and 60%, thus greatly reducing the overall weight of the centrifugal force and the bearing.
