Ballscrew actuator that we ordered through Kiwi Motion looks and performs great. Swiss quality!
Well Specified Linear Actuators
The actuator runs smoother and quieter than previously used actuators. Also, it runs faster from start, so we can drive faster.

Superb service from start to finish
I can just tell Kiwi what I need and I can trust they will go away and sort the right product at the right time.

Well packaged Linear Shafts
Well packaged item, as described and dispatched quickly. Thank you
High Quality Linear Rail and Guides
We received the new components on the Wednesday afternoon and installed them the following morning. Parts were perfect and of great quality!
That you kindly for your assistance, fantastic service you’re running over there!

Product Details

SFNUR Din Standard Series Ballnut
Introducing the SFNUR high load, DIN standard ballnut. Through years of research and design the SFNUR nut excels in offering smooth and quiet linear motion with excellent levels of rigidity. Offering zero backlash and enhanced dust protection this ballnut will cater for a wide range of applications from CNC milling, to pick and place assemblies to precision medical automation, throughout the UK & Ireland and beyond.
FEATURES ENGINEERED FOR EXCEPTIONAL PERFORMANCE
Space Saving Recirculation Method: Due to the innovative internal recirculation tubes, the SFNUR nut offers high load capacity in a compact form.
Small Driving Torque: With a driving torque requirement to only a third of that of a ACME leadscrew, the SFNUR ballscrew assembly offers high performance characteristics.
Inherently Rigid: The SFNUR nut offers excellent rigidity due to full ball contact with the ball raceway, offering enhanced stiffness.
Anti-Backlash: All Kiwi Motion ballscrew assemblies are anti-backlash and extremely rigid. Peace of mind when incorporating precision linear motion into your next machine design.
High Dust Protection: An enhanced sealing design means excellent protection from dirt and debris, allowing this ballscrew assembly to perform in the most demanding of environments.
Precision Accuracy: Micron accuracy and repeatability is guaranteed with all Kiwi Motion ball screw systems to suit any application where precision is a necessity.
Low Noise: With precision ground ball raceways and an end cap deflection recirculation method, a low decibel level is achieved.
SPECIFICATIONS TO MEET DIVERSE ENGINEERING REQUIREMENTS
Available Diameters: Available in diameters, 12, 16, 20, 25, 32, 40 and 50, 63 and 80mm our ball screw systems are designed to suit a wide array of design specifications.
