1. Pictures of Zirconia Ceramic Ball Bearing 6211

2.Descriptions of  Zirconia Ceramic Ball Bearing 6211

1.Manufacture full ceramic ball bearings from 1995.

2.Excellent and stable quality.

3.Plenty of stocks.

With excellent performance, zirconia ceramic ball bearings have electrical and magnetism resistance, wear and corrision resistance, lubrication and maintenance free. It could work in awful environment while the ordinary bearings are not qualified. And also its cost is much lower than that of silicon nitirde ceramic ball bearings. They are widely used in the areas of aviation, aerospace,marine,petroleum, chemical, automotive, electronics, metallury, electric power,textile, medical equipment and other applications.

Rings:  

The inner and outer rings are made by zirconia ceramic;

Balls:

The balls are made of zirconia ceramic;

Cages:

The retainers are made by PTFE/PEEK;

Meanwhile, we can also produce a series of deep groove ball bearing, full complement balls, self-aligning ball bearings, angular contact ball bearing, insert bearing and so on.
