The Angular Contact Ceramic Ball Bearing H7000C-2RZ HQ1 is the pinnacle of high-speed spindle technology. Engineered with Silicon Nitride (Si3N4) ceramic balls and high-carbon steel rings, this hybrid bearing is designed to operate at an incredible grease-lubricated speed of 106,700 RPM. The ceramic balls are 40% less dense than steel, significantly reducing centrifugal force and internal friction. This results in cooler operating temperatures, minimal thermal expansion, and a vastly extended service life compared to traditional steel bearings, making it ideal for ultra-precision dental, aerospace, and micro-machining spindles.
