Compared to ordinary shaft steel bearings, ceramics as raw materials used in the history of the bearing is relatively shallow. However, since the ceramic as a substitute for the new material of the shaft, indicating that the ceramic bearings in the performance can be achieved by ordinary shaft steel bearing application effect, even in some characteristics far more than ordinary shaft steel bearings. Strong force in this we generally summed up into three advantages, to enjoy the new material of this new star of the true ability of it.

Speaking of three advantages, bear the brunt of the most prominent advantage is the corrosion resistance of ceramic bearings. As the ceramic material itself has corrosion-resistant properties, can be used in strong acid, alkali, inorganic, organic salts, seawater and other fields, so our ceramic bearings are almost afraid of corrosion, corrosive media in the harsh conditions of the operation is completely under.

Second, say the speed of ceramic bearings, ceramic bearings made of bearing friction coefficient is very low, speed and acceleration ability, can be dn value of more than 300 million conditions of operation, and slipping, wear and heat can be reduced. As the elastic modulus of the ceramic than steel, stress is not easy to deformation, it is conducive to improve the working speed, and to achieve high accuracy. In particular, silicon nitride ceramic bearings, which compared to zirconia ceramic bearings can be applied to higher speed and load capacity of the operating environment.

The last point is that ceramic bearings have a longer life than ordinary shaft bearings. As the density of ceramic materials than steel, the weight is much lighter, so the rotation of the outer ring when the centrifugal effect can be reduced by 40%, which makes the ceramic bearing life greatly extended. In addition, the impact of thermal expansion and contraction of the ceramic than the steel is small, so the gap in the bearing is certain, the ceramic bearings can adapt to the environment that has a very big temperature changes.
