Ceramic Thrust Bearings Ceramic Thrust Bearings, We have 2 types of ceramic bearing, hybrid ceramic bearing and full ceramic bearing, the hybrid ceramic bearing has steel inner and outer rings with ceramic balls, as for the full ceramic bearing; The inner, outer rings and the balls are made of ceramic. There are many kinds of ceramic materials, the most common ceramic materials are Si3N4 that stands for the silicon nitride ceramic material and is black colored,

Ceramic bearing steel bearing, compared with the advantage is:1, speed higher than steel, ceramics, can reduce operating in the same precision and the centrifugal force, improve speed.2, high precision occasions: ceramic hardness and young modulus is higher than that of the steel, the same load, the smaller, thus mechanical deformation can be applied to more precise.Three, use longer than that of the steel bearing, the highest prolonged five times
