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!

SCE40UUN
Product Details

SCE40UUN Linear Bearing – 40mm Shaft Diameter
Robust Linear Movement for Large Machinery
The SCE40UUN, closed, housed linear bearing block delivers powerful, precise linear motion, making it an ideal choice for large-scale machinery.
Manufactured to European metric standards, it ensures full interchangeability with standard linear components and integrates reliably into heavy industrial and construction equipment.
With an inner diameter of 40mm and a length of 90mm, this bearing provides significant load support and exceptional operational stability.
Ideal for Automated Warehousing and Large-Scale Robotics
This bearing is particularly well-suited for automated warehousing systems, large-scale robotic arms, and heavy-duty CNC machinery where substantial loads and continuous, accurate motion are required.
Its robust build quality ensures consistent performance in the most challenging industrial settings.
Engineered for High Performance and Longevity
The SCE40UUN is built with a highly rigid aluminium housing, providing superior structural integrity and making installation straightforward even for large assemblies.
The self-aligning feature allows for effective compensation of minor mounting imperfections, ensuring smooth operation.
Equipped with double rubber seals, this bearing offers outstanding protection against environmental contaminants, leading to a longer service life and reduced maintenance intervals.
As part of Kiwi Motion’s European-standard SCE Series, the SCE40UUN ensures compatibility with metric linear systems and simplifies maintenance, replacement, or system upgrades.
SCE40UUN System Compatibility
Compatible with Kiwi Motion’s CF53 Steel, Chrome Plated Steel, and Stainless-steel linear shafts, the SCE40UUN is a dependable choice for large-scale, high-load linear guidance.
