Ø25mm CF53 Induction Hardened Linear Bearing Shaft - Cut To Length

Ø25mm CF53 Induction Hardened Linear Bearing Shaft – KM-W-25

Precision shaft for heavy-duty industrial linear motion

The KM-W-25, 25mm linear bearing shaft from Kiwi Motion is a robust, high-strength solution designed to deliver precise and reliable linear motion in heavy-duty industrial applications.

With a substantial 25mm diameter, this shaft offers excellent rigidity and surface durability, making it ideal for systems where shaft deflection must be kept to an absolute minimum.

Each 25mm linear bearing shaft is manufactured from CF53 steel, a material chosen for its superior hardness and mechanical stability.

The shaft undergoes an induction hardening process to create a wear-resistant surface, capable of withstanding continuous use in demanding environments.

It is then precision ground to an h6 tolerance, with roundness maintained within 6 µm and straightness controlled within 0.15 mm per metre.

These tight tolerances enable smooth, low-friction linear motion and help ensure consistent system accuracy across extended duty cycles.

Applications for the 25mm linear bearing shaft

The 25 mm diameter of the KM-W-25 shaft makes it particularly well suited to large, high-load linear motion assemblies where stiffness and precision are essential.

Common applications include:

• CNC platforms requiring extended travel with high positional accuracy
• Large gantry systems for automated machining or handling
• Heavy-duty material transport systems in production environments
• Automated handling machines for factory automation
• Robotics and precision assembly lines

The combination of high rigidity and excellent wear resistance allows the KM-W-25 to perform reliably under repeated use and heavy loads.

It is well suited to maintaining precise alignment in linear motion systems that operate continuously or in environments where vibration and shock are present.

Custom Lengths for Seamless Integration

Each 25mm linear bearing shaft is cut to the customer’s required length with a precision tolerance of ±0.1 mm.

This ensures simple and accurate integration into bespoke machine designs or existing motion assemblies. Custom end machining is available upon request.

Compatible with Kiwi Motion’s Bearings and Shaft Supports

The 25mm linear bearing shaft is designed to work seamlessly with Kiwi Motion’s full range of linear bearings and shaft supports.

This compatibility supports easy installation and reliable long-term performance, helping engineers create linear motion systems that deliver smooth, accurate travel with minimal maintenance.

For industrial automation projects requiring a high-strength, precision shaft with excellent stiffness and durability, the KM-W-25 offers a proven and cost-effective solution.
