1.Manufacture  full silicon nitride 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 inside and outside rings are made by silicon nitride(Si₃N₄);

Rollers:

The balls are made of silicon nitride ceramic(Si₃N₄);

Cages:

The cages are made by PTFE/PEEK.

And we can also produce deep groove ball bearing, full complement balls, self-aligning ball bearings, angular contact ball bearing, insert bearing.
