Hot sales China made Full Ceramic Ball Bearing 634
Ceramic SI3N4 ZRO2 Deep groove ball bearings :
Deep groove ball bearing is suitable for Sustain radial,acial,or compasite load.
Provide both high-running accuracy &high-speed operation , Can replace high speed angular contact ball bearings
.
1)Full ceramic bearing Zro2 materia :
Full ceramic bearing Zro2 material has perfect propriety such like suitable for low and high temperatures,high load capacity,corrosion resistance,nonmagnetic insulated and self lubrication.thus it suit for the specific applications which are not available for bearing steel and hybrid construction ceramic ball bearing materials.
2)Full ceramic bearing Si3N4 materia:
Full ceramic bearing Si3N4 material has similar propriety as ZrO2 material,besides it has low weight.good wear resistance.high hardness.and it can bear higher temperature than ZrO2 material.

Ceramic bearing:
1.Ceramic 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 Bearings, Si3N4 stands for the silicon nitride ceramic material and is black colored,
3.Ceramic Bearings, SiC stands for the silicon carbide material and is alsoblack colored.
4.Ceramic 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
More Ceramic Ball bearings are available in our company as following tables:
