Angular Contact Ceramic (Hybrid) Bearings

An angular contact ceramic bearing (hybrid bearing) has silicon-nitride balls in steel rings. It runs cooler and faster than an all-steel bearing, which is why high speed CNC spindles use it. TriQuench India lists H7000C to H7012AC sizes and 7205C.

Angular Contact Ceramic Bearings: overview

Hybrid ceramic bearings are the standard in high speed router and motorized spindles. Replace them in matched pairs with the same contact angle (C or AC) and preload, and have the spindle balanced after replacement.

Angular Contact Ceramic Bearings: frequently asked questions

Can I replace ceramic spindle bearings with steel ones?

Not on a spindle designed for ceramic bearings at high speed: steel balls are heavier and run hotter, so the spindle may overheat or fail at its rated RPM. Replace like with like, same size, contact angle and class.
