Due to ultra-high-speed motors for Hybrid Vehicles increasing in size and output, NSK has developed a large-diameter bearing (inner diameter of 160 mm and outer diameter of 190 mm) which delivers the fastest rotation speeds of any ball bearing for automotive applications with two million dmn (1)
Capable of ultra-high-speed rotation exceeding two million dmn. Faster than any other ball bearing used for automotive applications
Higher power output in drive motors and generators of hybrid cars, helping improve fuel efficiency and driving performance
(1) dmn : bearing diameter x maximum rotating speed
