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,

Full ceramic bearing side over the ball the ball with Tim gap, because no-cage structural design, the structure than the standard number of ceramic ball bearings mount to increase its load capacity, other materials can also avoid the restrictions cages can be to ceramic ceramic bearing cage type all effects of corrosion and heat resistance. Drawback is that because there is no cage, not suitable for high speed bearings in the series.
