2.Descriptions of Si3N4 ceramic bearing

1.Manufacture Si3N4 ceramic bearing from 1995.

2.Excellent  and stable quality.

3.Plenty of stocks.

Ceramic ball especially silicon nitride ceramic ball have the following performance as low density, high strength, low friction coeffecient, electrical and magnetism resistance, wear resistance, well rigidity, lubrication and maintenance free when working, it's the best choice for rollers and rings for bearing wich are used in high speed, long accuracy and long life environments. So they are widely used in aviation, aerospace, marine, petroleum, chemical, automotive, electronics, metallurgy, electric power, textile, medical equipment and other fields.

Rings:  

The rings (the inside and outside) are made by silicon nitride ceramic;

Rollers:

The rollers are made silicon nitride ceramic too;

Retainers:

The retainers are made by PTFE, nylon 66, polyether acid sub-ammonia, stainless steel.
And we can produce deep groove ball bearing, full complement balls, self-aligning ball bearings, angular contact ball bearing, insert bearing.
