Ceramic ball bearing ball race bearings

Ceramic ball bearing Features:

1.Ceramic ball Bearings have two types of ceramic bearing, hybrid ceramic bearing and full ceramic bearing,

 The hybrid ceramic bearing has steel inner and outer rings with ceramic balls,

2.Ceramic ball Bearings, Si3N4 stands for the silicon nitride ceramic material and is black colored,

3.Ceramic ball Bearings, SiC stands for the silicon carbide material and  is alsoblack colored.

4.Ceramic ball Bearings,  ZrO2 stands for the zirconium dioxide, also known as zirconia or zirconium oxide, they   are white colored, a ZrO2 ball looks exactly like a pearl.

5.The ceramic material is not stronger than steel, but ceramic bearing are lighter and have lower friction than steel,  which makes ceramic bearing go faster with lower heat generated.
