UBNS Ball Screw Spline - Potential Alternative to THK BNS-V

UBNS Series - Ball Screw Spline (Combined Rotary and Linear Motion)

UBNS Series ball screw spline combines a ball screw and a ball spline in one compact unit, enabling both rotary indexing and linear feed motion from a single actuator. This integration saves space, reduces component count and simplifies machine design.

Key features:

• Ball screw + ball spline integrated design for rotary and linear motion

• Compact single-unit construction for small installation space

• High positioning accuracy with low friction

• Ideal for picking, rotating and placing operations in one station

• Custom strokes and end machining available

Typical applications: multi-axis pick-and-place, screw fastening stations, IC test handlers, robotic wrist mechanisms and automated production lines requiring rotary positioning with linear feed.
