    THK NS-V Ball Screw/Spline (Low Inertia, Linear Motion, 16-25)

    THK NS-V Ball Screw/Spline (Low Inertia, Linear Motion, 16-25)

    The THK NS-V is a precision ball screw/spline unit for linear motion, a low-inertia type with a further reduced outer diameter and nut inertia compared with NS-A.

    Key features

    • Ball screw grooves and ball spline grooves cross-machined on a single shaft
    • Dedicated support bearings mounted directly on the nut outer diameters
    • Linear motion with the ball spline nut acting as rotation stop and guide
    • Compact feed unit combining screw drive and spline guide on one shaft
    • Series character: low-inertia type with a further reduced outer diameter and nut inertia compared with NS-A
