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

SK40 (40mm) SK Series Shaft Support for Extreme Load Applications
The SK40 Series shaft support, measuring 114mm in length, 36mm in width, and 96mm in height, and constructed from lightweight aluminium, provides robust and precise mounting for your 40mm linear shafts. Its compact yet inherently rigid design is an excellent choice for a variety of the most demanding industrial applications throughout the UK & Ireland and beyond, streamlining the assembly process for design engineers.
Key Features & Benefits:
-
Compact Design: The optimised footprint of the SK40 support helps maintain a streamlined machine layout, even when integrating into the largest and most complex systems. This is particularly beneficial for heavy-duty industrial automation and large-scale production machinery where maximising operational space while ensuring structural integrity is critical.
-
Inherently Rigid: This SK40 shaft support offers unparalleled support and unwavering stability for your 40mm linear shaft. It is ideal for applications demanding maximum precision and exceptionally high load capacities in large format CNC machines or for providing robust support in heavy-duty material handling equipment like robotic transfer systems, ensuring consistent and reliable performance under the most significant stresses.
-
Lightweight Construction: Manufactured from high-grade aluminium, the SK40 shaft support is remarkably lightweight despite its formidable strength. This contributes to a lower overall machine mass, which is advantageous for very large gantry systems requiring maximum payload capacity and for automated guided vehicles (AGVs) transporting heavy components, where reducing inertia and improving energy efficiency are crucial design considerations.
-
Easy Mounting: The intuitive axial tightening bolt on the SK40 support ensures a quick and secure fit with minimal effort, saving valuable time during machine setup. This efficiency is important for rapid deployment of bespoke industrial solutions and for complex machinery where swift maintenance and component replacement are essential to minimise operational downtime.
Compatibility & Specifications for SK40:
This SK40 support is specifically designed for 40mm diameter linear shafts, ensuring seamless integration into your most demanding linear motion systems. It pairs perfectly with our CF53 steel, chrome-plated steel, and stainless steel linear shafts, providing a comprehensive solution for your heavy-duty linear guidance requirements. The SK series is available for diameters 8, 10, 12, 14, 16, 20, 25, 30, and 40mm, offering a suitable option for many engineering specifications.
