Q: Why do people use ceramic bearings?

First, because ceramics are almost not afraid of corrosion, ceramic rolling bearings are suitable for operation under harsh conditions full of corrosive media.

Second, because the density of the ceramic rolling ball is lower than that of steel, and the weight is much lighter, the centrifugal effect of the outer ring during rotation can be reduced by 40%, and the service life is greatly extended.

Third, ceramics are less affected by thermal expansion and contraction than steel, so when the bearing gap is constant, the bearing can be allowed to work in an environment where the temperature difference changes more drastically.

Fourth, since the elastic modulus of ceramic is higher than that of steel, it is not easy to deform when subjected to force, so it is beneficial to increase the working speed and achieve higher accuracy.
