Ceramic ball bearing could have identical structure with steel bearing.

XW 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, Stainless Steel Flanged Ball Bearings with Ceramic Balls ABEC-7 quality, this is a popular size that be used in Slot Car Axle and many applications. 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, SiC stands for the silicon carbide material and also is black colored. and the ZrO2 that stands for the zirconium dioxide, also known as zirconia or zirconium oxide, they are white colored, a ZrO2 ball looks exactly like a pearl.


The Ceramic ball bearing advantageous in having a longer service life, lower friction resistance, higher seizure resistance, higher corrosion resistance, higher rigidity, higher temperature resistance ( up to 800C) lightweight (40% of bearing steel), in high-speed, Ceramic by its nature is lighter than steel by about 2/3 the weight, it is harder than steel when it is in ball form and it is virtually frictionless because it is non-porous. A ceramic hybrid bearing has steel races with ceramic balls and a full ceramic bearing has ceramic races and balls.
