What Is An Angular Contact Ceramic Bearings?
Angular contact ceramic bearings use ceramic balls (typically silicon nitride) instead of steel, reducing weight and heat generation to enable higher spindle RPM with lower thermal expansion. TriQuench India supplies ceramic bearings for high-speed spindle motors up to 60,000 RPM.

Frequently Asked Questions — Angular Contact Ceramic Bearings
What is the advantage of ceramic bearings over steel bearings in a spindle?
Ceramic balls are lighter and harder than steel, generating less heat at high RPM and resisting thermal expansion better, which allows spindles to run faster with less runout drift.
Are ceramic bearings worth the extra cost for a CNC spindle?
For high-RPM applications (above roughly 24,000 RPM) or continuous-duty use, ceramic bearings' reduced thermal runout and longer service life typically justify the added cost.
