Application:

In recent years, ceramic bearings have been widely used in various fields.Aerospace, navigation, nuclear industry, petroleum, chemical industry, qingfang industry, machinery, metallurgy, electric power, food and other fields need to work under high temperature, high speed, strong corrosion, dry friction and other special working conditions.

Advantage:

1. High rotation speed and acceleration capacity -- it can operate under the condition of dn value exceeding 3 million, cutting slip, wear and heat can be reduced.
2. Long life, wear resistance -- the fatigue life of all-ceramic bearing is 10-50 times longer than that of all-steel bearing, and the life of mixed ceramic bearing is about 3-5 times longer than that of all-steel bearing.
3. Little lubrication required - ceramic materials have low friction coefficient. Ceramic bearings lubricated with oil still have no less lubrication capacity than conventional lubricants commonly used in steel bearings when the lubricating oil becomes thin or lean.
4. Corrosion resistance - ceramic materials are inert, so they are more resistant to corrosion and wear.
5. High rigidity - due to the high elastic modulus of ceramic material, its rigidity is 15-20% higher than ordinary steel bearings.
6. High temperature resistance - all-ceramic bearings can work at temperatures above 500C.
7. Non-magnetic non-conductive - ceramic bearings are not subject to magnetic or electrical damage.
