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
