World-class performance with the highest available speed

The highly functional High-speed Integrated Motor Spindle for Machining
Centers maximizes the machining ability of Class #40 high-speed machining
centers. NSK realized the world’s highest speed performance of 20 000 min–1
by thoroughly developing heavy cutting ability, ultra low noise, and lower
environmental load.

Best-in-class speed

NSK’s ROBUST Series bearings and
FANUC’s integrated, high-performance
motor deliver the highest speed for
this class of spindle.
The maximum speed of 20 000 min–1 (dmn 1.7×106)
was achieved under position-preloaded grease
lubrication.
Bearing technology + design technology

Up to 20 000 min–1 (dmn 1.7×106)

under position-preloaded grease lubrication.

Ultra low noise

NSK’s design technology combined with
its outstanding bearing technology and
proven expertise result in ultra low noise
of 69 dB with reduced vibration at 20 000 min–1.
