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

Ø16mm CF53 Chrome Plated Induction Hardened Linear Bearing Shaft – KM-WV-16
Precision shaft for desktop CNC machines, 3D printers, and industrial automation
The KM-WV-16, 16mm chrome plated linear bearing shaft from Kiwi Motion is engineered for reliable, smooth linear motion in environments where corrosion resistance and extended wear life are essential.
With a 16 mm diameter, high-surface-hardness chrome plated finish, and excellent rigidity, this shaft is ideal for a wide range of light to medium-duty automation and motion control systems.
Each KM-WV-16 shaft is manufactured from CF53 steel, a material chosen for its excellent combination of core strength and surface durability.
The linear bearing shaft is induction hardened to achieve a minimum surface hardness of 62 HRC, providing excellent wear resistance.
It is then chrome plated, giving superior protection against corrosion caused by humidity, coolant spray, washdown, and outdoor exposure.
The 16mm chrome plated linear bearing shaft is precision ground to an h7 tolerance, with roundness controlled within 8 µm and straightness maintained within 0.20 mm per metre. These precise tolerances ensure low-friction, accurate linear motion.
Applications for 16mm chrome plated linear bearing shaft
The 16 mm KM-WV-16 shaft is a popular choice in both industrial equipment and high-performance hobbyist machines.
Its combination of rigidity, corrosion resistance, and durability makes it suitable for:
- Desktop CNC machines and router sleds
- Medium to large-format 3D printers
- Laboratory automation equipment exposed to chemical or moisture environments
- Food processing and packaging machinery requiring frequent washdown
- Outdoor motion systems and positioning equipment
The hardened chrome plated surface provides excellent long-term performance even in harsh conditions, helping maintain precise alignment and consistent motion over the life of the system.
Custom Lengths and End Machining Options
Each 16mm chrome plated linear bearing shaft is cut to your specified length with a precision tolerance of ±0.1 mm, ensuring exact integration into machine builds.
For bespoke requirements, Kiwi Motion offers a custom end machining service. We can provide chamfers, threads, flats, tapped holes, or other end features to suit your application and simplify assembly.
Compatible with Kiwi Motion’s Bearings and Shaft Supports
The 16mm chrome plated linear bearing shaft is fully compatible with Kiwi Motion’s linear bearings and shaft supports. This guarantees a precise fit and dependable long-term performance in any linear motion assembly.
For motion systems requiring a balance of stiffness, corrosion resistance, and high wear life, the KM-WV-16 shaft offers a proven and versatile solution.
