2.Descriptions of  Cheap Price Ball Bearings

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 chrome steel/silicon nitride/zirconia/plastic

Rollers:

The balls are made of zirconia/silicon nitride/ plastic

Retainers:

The retainers are made by PEEK/PTFE.

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