Define "high speed." What is considered leading edge today?

Anthony/Timken: High speed, referred to as dN, is calculated by multiplying the bearing bore diameter in millimeters by the shaft rpm. If the solution to this equation is greater than 1 million, it is often considered highspeed.

George/NSK: High speed in linear motion depends on the type of linear motion product. In terms of ballscrew drives, NSK has a 50-mm-diameter x 100mm-lead ballscrew capable of...
