Hybrid ceramic bearings may be relatively uncommon, 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 retainer + 2RS/ZZ. Hybrid ceramic bearings have the following four advantages during use.

(1) High temperature resistance and low thermal expansion coefficient of ceramic balls. In high temperature environments, the bearing balls will not expand due to temperature, which greatly increases the operating temperature of the entire bearing. The temperature of ordinary bearings is about 160 degrees. Ceramic balls Can reach 220 degrees or more.

(2) The speed is high. Ceramic balls have oil-free and self-lubricating properties, and the friction coefficient of ceramic balls is small, so ceramic ball bearings have a high speed. Bearings using ceramic balls are more than 1.5 times the speed of general bearings.

(3) Long life, ceramic balls can be used without any grease, that is to say, even if the grease dries out, the bearing can still operate, so as to avoid the occurrence of premature bearing damage caused by the grease dries out in ordinary bearings. According to us Testing and feedback from some customers, the service life of bearings after using ceramic balls is 2-3 times that of ordinary bearings.

(4) Insulation. Bearings 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. In this way, the bearing It can be used in a conductive environment. This is also the greater advantage of hybrid ceramic bearings.
