Ballscrew actuator that we ordered through Kiwi Motion looks and performs great. Swiss quality!
The actuator runs smoother and quieter than previously used actuators. Also, it runs faster from start, so we can drive faster.
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 item, as described and dispatched quickly. Thank you
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
The KM-W-8, 8mm linear bearing shaft from Kiwi Motion is a precision-engineered component designed to provide smooth, repeatable motion in a wide range of automation and linear motion applications.
With an 8 mm diameter and robust CF53 steel construction, this shaft delivers excellent performance in both static and dynamic systems where durability and positional accuracy are key.
Each KM-W-8 shaft is precision ground and induction hardened, creating a hard, wear-resistant surface that ensures long service life even under repeated cycling with ball bushings.
The 8mm linear bearing shaft is finished to an h6 tolerance, with roundness controlled within 4 µm and straightness within 0.20 mm per metre.
This level of precision guarantees a stable, low friction fit with linear bearings, supporting accurate linear movement across the full length of travel.
The 8 mm diameter KM-W-8 is a versatile choice for low to medium load applications across industrial, laboratory, and automation environments. Its size offers a significant step up in stiffness compared to smaller shafts, with only a modest increase in mass. Typical applications include:
Thanks to its hardened surface and precision finish, the 8mm linear bearing shaft resists wear, scoring, and deflection under load, helping to maintain reliable and repeatable motion in demanding environments.
Every KM-W-8 shaft is cut to your specified length, with a length tolerance of ±0.1 mm. This allows fast, simple integration into both custom-built and OEM mechanical assemblies.
Designed for perfect compatibility with Kiwi Motion’s linear bushings and shaft support blocks, the KM-W-8 ensures an exact fit and optimal long-term performance.
This compatibility simplifies system design and maintenance while helping engineers achieve precise, consistent motion in their automation and linear motion systems.
For industrial linear motion where stiffness, durability, and precision are required, the KM-W-8 offers exceptional value and reliability.
