Application:

1. Ceramic bearing has the characteristics of high temperature resistance, cold resistance, abrasion resistance, corrosion resistance and insulation, and can be used in extremely bad environment and special conditions.

2. Ceramic  bearings can be widely used in aviation, spaceflight, navigation, petroleum, chemical industry, automobile, electronics, metallurgical, power, textile, pumps, medical equipment and scientific research.

Characteristics of Ceramic Bearings:

1.High hardness,wearing resistance,low friction coefficient,good self-lubrcating

2.High temperature application,better thermal shock resistance

3.Higher fracture toughness,better shock resistance

4.Excellent resistance to chemical corrosion,it can endure all of acid corrosion and alkalescent corrosion,it's unstable for most strong alkali and molten salt.

5.The performance of contant similar to bearing steel ,similar forms of fatigue spalling

Advantages of Ceramic Bearings:

1.59% lighter than steel

2.The elastic modulus is 44% larger than steel

3.Hardness is higher than steel

4.Low friction

5.It can withstand temperature changes

6.Easy to access to almost perfect surface finish

7.High temperature resistance

8.Never rust,can work under the condition of no oil lubrication

9.More resistant to chemical corrosion

10.No metal pollution

11.No magnetism

12.Electric insulation

13.There is no adhesive wear

14.no reaction with metallic melts
