    THK BNS-V Ball Screw/Spline (Low Inertia, Linear + Rotary, 16-25)

    THK BNS-V Ball Screw/Spline (Low Inertia, Linear + Rotary, 16-25)

    The THK BNS-V is a precision ball screw/spline unit for linear + rotary motion, a low-inertia type with a further reduced outer diameter and nut inertia compared with BNS-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
    • Three motion modes (rotary, linear, spiral) by rotating or stopping the spline nut
    • Suited to SCARA robot Z-axes, assembly robots, automatic loaders and ATC units
    • Series character: low-inertia type with a further reduced outer diameter and nut inertia compared with BNS-A
