THK BNS-V Series Low-Inertia Ball Screw/Spline

The THK BNS-V Series Low-Inertia Precision Ball Screw/Spline combines a ball screw and ball spline in a compact unit for linear and rotary motion. Its low-inertia design supports responsive motion while maintaining reliable load and torque performance.

The BNS-V Series is available in 16, 20 and 25 mm sizes, with screw leads of 16 to 25 mm and a DN value of 100,000. The integrated ball spline provides rated load, moment and torque capacity, making the series suitable for compact precision motion applications requiring fast response and efficient operation.
