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

SSPF Ball Spline
Introducing the SSPF ball spline from NB, a simple, compact linear system designed to revolutionise the way design engineers approach linear motion. This series is an embodiment of our commitment to providing innovative, high load, high speed linear solutions that cater to a diverse range of engineering needs across the UK & Ireland, and beyond.
FEATURES ENGINEERED FOR EXCEPTIONAL PERFORMANCE
Compact Footprint: Compact in form, the SSPF series offers high load capacity and due to the large ball contact area, a long travel life.
Ground Spline Shaft: NB ball splines are precision ground to ensure tight tolerances allowing for smooth, quiet, super accurate linear motion. The SSPF series is also available with non-ground commercial shaft.
High Accuracy Torque Transmission: Due to the effective contact angle between raceway and balls, the SSPF ball spline can transmit large torque.
High Rigidity: The large contact area between raceway and ball bearings ensures a highly rigid linear motion system.
Low Noise: NB pride themselves on offering the quietest, smoothest running ball splines in the industry. With the unique recirculation design in both the spline and rotational sections, a low decibel is realised.
High Accuracy: With accuracy figures of just 6µm/100mm, an NB ball spline will suit even the most demanding precision applications.
Easy Machining: Since a round shaft with raceway grooves is used, NB ball splines can easily be custom machined.
SPECIFICATIONS TO MEET DIVERSE ENGINEERING REQUIREMENTS
Available Sizes: Available in a huge range of mm diameters from 6, 8, 10, 13, 16, 20, 25, 30, 40, 50, and 60 our SSPF NB ball splines are designed to suit a wide array of design specifications.
Anti-Corrosion Option: With the option to choose an anti-corrosion ball spline assembly for more demanding environments, the SSPF becomes even more suitable for more applications.
Hollow Shaft: NB ball splines and rotary ball splines are available with hollow shafts to allow for running cables, air piping and weight reduction, ensuring complete flexibility for all applications.
