6803 ceramic bearing, full ceramic zirconia bearing

6803 ceramic bearing

1. Ceramic Bearing

Ceramic bearings are  anti-magnetic, insulating, oil-free self-lubricating, corrosion resisting and high speed. They work in terrible conditions while the ordinary bearings cannot be qualified, and much cheaper than silicon nitride. They are widely used in aviation, aerospace, marine, petroleum, chemical, automotive, electronics, metallurgy, electric power, textile, medical equipment and other domains.  

Materail of bearing:

Rings:zirconia ceramic

Balls:zirconia balls or silicon nitride balls.

Cage: PTFE, nylon 66, PEEK,SS304.

2. Silicon Nitride(Si3N4)Ceramic Properties:

3. Application:

It is widely used in aerospace, mechanical industry, chemical industry and petroleum industry. Specified for 

use in such high-technology industries such as hybrid bearings, aerospace and defense.

4. Every step quality control

1.Raw material checking when suppliers deliver to our factory to ensure no quality problem at the very beginning;

2.Instrument and equipment checking every time before use.

3.Size checking, roundness checking, crushing load test etc. by special measuring tool.

5. Fair

We have been to a lot fairs and the latest fair is 2015 HANNOVER MESSE Germany.
