FAQ
1. What is a full ceramic ZrO₂ bearing?
It uses zirconia ceramic for the inner and outer rings and ceramic balls as rolling elements.
2. What is the difference between full ceramic and hybrid ceramic bearings?
Full ceramic bearings use ceramic rings and balls, while hybrid bearings normally use steel rings with ceramic balls.
3. Are ZrO₂ bearings electrically insulating?
Yes. Zirconia is an electrically insulating ceramic material.
4. Are ZrO₂ bearings corrosion resistant?
Yes. ZrO₂ does not rust and has good resistance to many corrosive environments. The cage, lubricant and seals should also be checked for chemical compatibility.
5. Can these bearings be used in water?
Yes, selected full ceramic configurations can be used in water and wet environments. The complete bearing construction should be confirmed for the specific application.
6. Can you supply matched angular contact bearing sets?
Yes. DB, DF and DT arrangements with specified preload can be supplied for suitable applications.
7. Can you customize the bearing?
Yes. Contact angle, cage, preload, clearance, lubrication, ceramic ball material and precision can be customized according to requirements.
8. How can I get a quotation?
Send us the bearing model, quantity and application details. If the model is unknown, send the bearing dimensions or drawing.
