What is the limiting speed for the H7002C-2RZ HQ1?

This ultra-high-speed micro-bearing is rated for an exceptional limiting speed of 81,700 RPM when used with high-speed grease lubrication.

How does the ceramic ball improve stability at 80,000+ RPM?

At such high velocities, steel balls suffer from 'centrifugal skidding' and massive heat build-up. Ceramic balls (Si3N4) are 58% lighter, which minimizes these forces, resulting in 40% less heat and significantly higher rotational accuracy.

Is this bearing suitable for dental equipment?

Yes, its 15mm bore and 81,700 RPM rating, combined with the hygienic and durable properties of ceramic, make it a premier choice for high-speed dental handpieces and surgical tools.
