About the advantages of hybrid bearing,Jinan Maolei Bearing Co.,Ltd. has something to say

Hybrid bearing may be less common, and the main configuration of hybrid ceramic bearings is a combination of inner and outer ring bearing steel/stainless steel + ceramic balls + PA66/stainless steel cage + 2RS/ZZ. Hybrid ceramic bearings have the following four advantages during use.

(1) High temperature resistance, small thermal expansion coefficient of ceramic balls, no expansion of bearing balls due to temperature in high temperature environments, which greatly improves the operating temperature of the entire bearing. The temperature of ordinary bearings is about 160 degrees, and ceramic balls can reach more than 220 degrees.

(2) High speed, ceramic balls have oil-free self-lubricating properties, and the friction coefficient of ceramic balls is small, so ceramic ball bearings have a high speed. According to statistics, bearings using ceramic balls are more than 1.5 times the speed of ordinary bearings.

(3) Long service life, the ceramic ball can be free of any grease, that is to say, even if the grease is dried, the hybrid bearing can still operate, thus avoiding the premature damage of the hybrid bearing caused by the drying of the grease in the ordinary bearing. According to our tests and feedback from some customers, the service life of bearings after using ceramic balls is 2-3 times that of ordinary bearings.

(4) Insulation. The hybrid bearing using ceramic balls can insulate the inner and outer rings of the bearing. Because ceramic balls are insulators, using ceramic balls between the inner and outer rings of the bearing can achieve the effect of insulation. Bearings can be used in conductive environments. This is also the biggest advantage of hybrid ceramic bearings.
