Ø20mm CF53 Induction Hardened Linear Bearing Shaft – KM-W-20

Precision shaft for general industrial linear motion applications

The KM-W-20, 20mm linear bearing shaft from Kiwi Motion is engineered to deliver precise and consistent linear motion in demanding industrial environments.

With a robust 20mm diameter, this shaft is designed to support higher load capacities while maintaining excellent positional accuracy and long service life.

Manufactured from CF53 steel, each KM-W-20 shaft undergoes a controlled induction hardening process that creates a highly wear-resistant surface.

This surface treatment allows the shaft to withstand the rigours of continuous operation, even in automation systems subjected to repetitive cycles and dynamic loading.

The 20mm linear bearing shaft is precision ground to an h6 tolerance, with roundness maintained within 6 µm and straightness within 0.20 mm per metre.

This ensures a smooth, low friction fit with linear bearings, promoting reliable and repeatable linear motion.

Applications for 20mm linear bearing shaft

The 20 mm diameter of the KM-W-20 shaft makes it an excellent choice for medium to heavy-duty linear motion applications where rigidity, wear resistance, and smooth operation are critical.

Typical uses include:

• Pick-and-place systems for automated assembly lines
• Heavy-duty linear actuators
• Precision transport systems in production lines
• Packaging and material handling equipment
• CNC machines and industrial robotic platforms

The shaft’s increased diameter and stiffness enable it to carry higher loads with minimal deflection, even over longer spans.

This makes it particularly well suited to industrial machines requiring long, stable linear travel with consistent accuracy.

Custom Lengths for Easy System Integration

Each 20mm linear bearing shaft is cut to the customer’s exact specified length, with a precision tolerance of ±0.1 mm. This allows for seamless integration into bespoke automation builds and OEM systems.

This precision cutting service reduces installation time and ensures a perfect fit straight from delivery. Additional end machining is available on request.

Compatible with Kiwi Motion’s Bearings and Shaft Supports

The KM-W-20 shaft is fully compatible with Kiwi Motion’s comprehensive range of linear bearings and shaft supports.

This ensures a precise and reliable fit, simplifying system design and helping maintain mechanical stability across various motion platforms.

For industrial automation applications requiring smooth, accurate, and durable linear motion, the KM-W-20 linear bearing shaft provides a trusted and versatile solution.
