Key words: ceramic bearing, ceramic ball bearing, Hybrid bearing, silicon nitride bearing, zirconia bearing |
|
We can provide full ceramic bearing and ceramic ball bearing. Full ceramic bearing means the inner ring, out ring, and ball are composed of ceramic materials, including zirconia and silicon nitride. Ceramic ball bearing, also named hybrid bearing, means the ball is ceramic, while the out ring and inner ring are steel. Ceramic ball bearing could have identical structure with steel bearing.
Retainer Material: PTFE, NYLON, PEEK, Stainless Steel or without retainer
Precision:P0 for full ceramic bearing and P1~P4 for ceramic ball bearing
Major bearing series: deep groove ball bearing, angular contact ball bearing, and thrust ball bearing. |

Properties advantage,compared with metal bearing |
|
1. Higher limit speed: ceramic is lighter than steel, and can effectively restrain the centrifugal force, therefore enhances the limit speed(2~3 times of that of steel bearing)
2. Higher precision usage: ceramic has higher hardness and elastic modulus than steel, which means ceramic bearing is stiffer, more rigid than steel bearing, thus can be used in higher precision condition.
3. Longer life: lighter ceramic leads to lower centrifugal force, thus extends bearing life. Furthermore, friction coefficient of ceramic is lower than steel, which also extends bearing life(4~6 times of steel bearing)
4. Higher temperature usage: ceramic is more mechanical stable at elevated temperature, thus could be used under higher temperature(can work under 800¡æ)
5. Temperature-variation usage: ceramic has a lower thermal expansion coefficient, thus the clearance and the tolerance variation is lower than those of steel bearing, which leads to a large temperature-variation range usage of ceramic bearing.
6. Better seizure resistance: ceramic has smaller thermal expansion coefficient, indicating less thermal deformation, thus enhance seizure resistance.
7. Could run without oil or grease: ceramic never rusts and is self-lubricated, thus can be used in situation that requires no oil or grease.
8. Resistant to acid, alkai and salt: chemical industry is the largest potential application industry of ceramic bearing to be exploited.
9. More suitable for magnetic application: our ceramic bearing is non-magnetic, which means it is difficult for magnetic particle to adhere on the race, thus reducing particle-abrasion.
Ceramic ball bearing is especially out standing in above first three items, while full ceramic bearing is outstanding in other items.
Full silicon nitride bearing is more superior than full zirconia bearing. It can endure higher temperature, and is more resistant to acid, alkai and salt. |
