Precision Bearing Solutions for
Speeds Exceeding 500,000 rpm
From dental turbine handpieces to high-speed electric motors, from turbochargers to precision spindles — ultra-high speed applications impose extreme demands on bearing precision, thermal management, lubrication, and service life. myonic and the MinebeaMitsumi Group deliver proven ultra-high speed bearing technology covering the full application range from 100,000 to 1,000,000 rpm.
Critical challenges at ultra-high speed
Beyond 100,000 rpm, every engineering detail becomes critically important.
Precision Balance
Even the slightest imbalance is exponentially amplified at high speed, causing vibration, noise, and premature failure. Minimum manufacturing tolerances and ABEC 9 / P2 precision grades are essential.
Thermal Management
High-speed friction generates significant heat, accelerating lubricant degradation and ball wear. Hybrid ceramic bearings (silicon nitride balls) effectively reduce heat generation through their low density and low thermal expansion coefficient.
Specialized Lubrication
Standard greases are centrifugally expelled or decompose at ultra-high speeds. Low-viscosity specialty greases (such as CF1 grade) with precisely controlled fill quantities are required.
Noise & Vibration Control
Precision cage design, preload control, and fully machined cages are critical for minimizing NRRO (non-repetitive run-out), which directly impacts end-product quality.
