may be not common, and configuration is mainly by the inner and outer ring of bearing steel/stainless steel + ceramic ball + pa66 / stainless steel retainer + 2 rs/zz combination. hybrid ceramic bearing four in use process has the following advantages.
1, high heat resistance, small thermal expansion coefficient of ceramic ball, under the environment of high temperature will not, because of the temperature result in bearing ball expansion, which greatly improve the bearing temperature, the use of ordinary bearing temperature at 160 degrees, ceramic ball can reach above 220 degrees.
2, high speed and the ceramic ball has the oilless self-lubrication property, friction coefficient is small, so the has the very high speed. the meter statistics using ceramic ball bearing is generally the speed of the bearing more than 1.5 times the speed.
3, long service life, ceramic ball can not add any grease, kill, that is to say, even if the oil bearing can operate, thus avoiding the ordinary bearing because grease off cause premature bearing damage. according to our test, and some customer feedback after using ceramic ball bearing life of 2-3 times that of the ordinary bearing.
4, insulation. using , can make the bearing between the inside and outside the circle of insulation, because of ceramic ball is an insulator, in bearings with ceramic balls between inside and outside the circle, can achieve the effect of the insulation. this allows the bearing can be used in conductive environment. this is one of the biggest advantages of hybrid ceramic bearing.
