    TBI MOTION SLF Ball Spline Flange Nut

    TBI MOTION SLF Ball Spline Flange Nut

    SLF is a ball spline with a round flange nut running on a precision ground spline shaft, transmitting torque while moving linearly.

    Key features

    • Balls contact the shaft grooves at 40 degrees for high load capacity and zero backlash
    • Sizes up to 20 mm use a two-row structure and sizes from 25 mm use four rows
    • The flange with four mounting holes makes installation simple; nuts can be ordered with solid or hollow shafts
