Frequently Asked Questions

What are the advantages of ceramic bearings over steel bearings?

Ceramic bearings offer higher speed capability, lower friction, corrosion resistance, non-conductivity, and longer service life in extreme conditions.

What materials do you use in your ceramic bearings?

We use high-purity silicon nitride (Si3N4), silicon carbide (SSiC), and zirconia (ZrO2) for balls and races, with PEEK or stainless steel cages.

Can you customize bearing sizes and specifications?

Yes, we offer full OEM and custom design services for size, material, precision grade, and sealing options.

What is the maximum temperature your bearings can withstand?

Silicon carbide bearings can operate up to 1650°C, while silicon nitride bearings are rated up to 1200°C in continuous use.
