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

That you kindly for your assistance, fantastic service you’re running over there!

Product Details

SFYR High Lead, High Speed Series Ballnut
Introducing the SFYR high lead, high speed ballnut. Through years of research and design the SFYR 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
End Cap Recirculation Method: Due to the innovative end cap recirculation tubes, the SFYR nut offers a high Dm-N value, offering high speed operation suitable for heavy load, high speed applications.
Inherently Rigid: The SFYR nut offers excellent rigidity due to full ball contact with the ball raceway, offering enhanced stiffness.
