ceramic ball bearing


ZrO2 full ceramic ball bearings Food machinery 608 bearing


ceramic ball bearing

1.High temperature-resistant
2.High accuracy ,High speed
3.Low friction, low noise



Ceramic bearing features:
1. Due to the ceramic almost afraid of corrosion, so the ceramic rolling bearing is suitable for the corrosive fluids in harsh conditions.2. As a result of the ceramic rolling ball density is lower than steel, more much lighter weight, therefore external ring spinning the centrifugal effect can be reduced by 40%, thus greatly extend the service life.
3. The ceramic is affected by heat bilges cold shrink is smaller than steel, therefore, when bearing clearance must be permissible 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.


Followings are the ceramic bearings displayed we are hot selling in the international market.
