At this year’s IMTS in Chicago (September 10 to 15) visitors can see in person THK’s latest ballscrew-spline BNS-V. Featuring an exceptionally compact and lightweight structure, the low inertia BNS-V enables quick starts and stops during high-speed operation.

The BNS-V is a stroke-rotary unit with ballscrew grooves and a ball spline groove that cross one another on a single shaft. The nuts of the ballscrew and the ball spline have dedicated support bearings directly embedded on the circumference of the nuts. HAHA Some advantages of the new ballscrew-spline BNS-V include a highly rigid shaft support, an angular-contact structure for highly accurate positioning and smooth motion with low noise.

The BNS-V is a downsized version of THK’s popular ballscrew-spline BNS-A. The BNS-V features a compact ø72 outer diameter, a low weight of 1.00kg and a low inertia of 2.00kg·cm2, contrasted with the BNS-A ø86 outer diameter, weight of 1.67kg and inertia of 4.32kg·cm2.
