First, because almost no fear of corrosion of ceramic, ceramic rolling bearings are suitable for operation in harsh conditions filled with corrosive media.
Second, since the density of ceramic rolling pellets is lower than that of steel and the weight is much lighter, the centrifugation effect on the outer ring can be reduced by 40% when rotating, thereby greatly extending the service life.
Third, ceramics are affected by thermal expansion and contraction less than steel, so the gap in the bearing a certain time, allowing the bearing temperature changes in the more violent environment work.
Fourth, because the elastic modulus of ceramic is higher than that of steel, it is not easy to deform when subjected to force, so it is helpful to improve working speed and reach higher accuracy.
In summary, the ceramic bearings in the application of so many advantages, so the major import bearings manufacturers such as: SKF bearings, NSK Bearings, FAG bearings are involved in this area and the introduction of the corresponding products.
