Advantages of Hybrid Ceramic Bearing


Hybrid ceramic bearings may be less common. The main configuration of the hybrid ceramic bearing is made from the combination of the inner and outer bearing steel / stainless steel + ceramic ball +PA66/ stainless steel maintainer +2RS/ZZ. Hybrid ceramic bearings have the following four advantages in use.


( 1 ) High temperature resistance. The thermal expansion coefficient of the ceramic ball is small. The bearing ball will not expand because of the temperature in the high temperature environment. This greatly improves the use temperature of the whole bearing. The temperature of the ordinary bearing is about 160 degrees, and the ceramic ball can reach more than 220 degrees.

(2) High speed. Ceramic ball has no oil self - lubricating properties. The friction coefficient of ceramic ball is small, so ceramic ball bearing has very high rotational speed. According to statistics, the bearing of ceramic ball is the speed of more than 1.5 times of the speed of the general bearing.

(3)Long life span. Ceramic balls can be added without any grease. That is to say, even if the oil is dry, the bearing can be operated. In this way, the premature damage of bearings caused by grease removal in ordinary bearings can be avoided. According to our tests and some customers’ feedback , the service life of bearings after using ceramic balls is 2 - 3 times that of plain bearings.

(4) Insulation. The bearing of the ceramic ball can insulate the inner and outer races of the bearing. Because the ceramic ball is an insulator , ceramic balls are used between the inner and outer rings of the bearing , so that the insulation effect can be achieved. This allows the bearing to be used in an electrically conductive environment . This is also the best advantage of hybrid ceramic bearings.
