The advantages of ceramic bearings

First, because the ceramic is almost not afraid of corrosion, so ceramic rolling bearings are suitable for operating in the harsh conditions that full of corrosive medium.

Second, because the density of the small ceramic rolling ball is lower than steel, and the weight is much lighter, so when rotation,the centrifugal effect on the external ring can be cut by 40%, thereby the service life can be much longer.

Third, the impact of thermal expansion and contraction on ceramics are smaller than steel, therefore, when the bearing clearance is some certain, may allow the bearings work in a environment that the temperature changes more dramaticly.

Fourth, as the ceramics of higher elastic modulus than steel, when on force is not easy deformation, so it is beneficial to improve the working speed and achieve higher accuracy.

In conclusion, due to the ceramic bearings have so many advantages in the application, so the major imports bearing manufacturers such as: SKF bearings, NSK bearings, FAG bearings are related to this area and launch of the corresponding products.
