:: Ceramic Bearing
:: One way Bearings
Ceramic Bearing all abouts, this is a dedicated website for ceramic bearing, 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, 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 material is not stronger than steel, but ceramic bearing are
lighter and have lower friction than steel, that makes ceramic bearing go faster with lower heat generated.
Well, we have them all here, just browse our website and buy them online :)
