Ø5mm CF53 Induction Hardened Linear Bearing Shaft - Cut To Length

Ø5mm CF53 Induction Hardened Linear Bearing Shaft – KM-W-5

Precision shaft for compact linear motion applications

The KM-W-5, 5mm linear bearing shaft from Kiwi Motion is a precision-engineered component designed to deliver smooth, repeatable motion in small-scale linear assemblies.

With a diameter of 5 mm, it is ideally suited to compact automation equipment, benchtop instruments, and lightweight linear motion systems where space, weight, and accuracy are key considerations.

Manufactured from high-grade CF53 steel, the KM-W-5 shaft offers exceptional surface hardness and wear resistance.

Each 5mm linear bearing shaft undergoes induction hardening, creating a durable outer layer that maintains its precision even after extended use.

The shaft is finished to an h6 tolerance, with roundness controlled within 4 µm and straightness within 0.25 mm per metre.

This ensures a precise fit with linear bearings, helping to achieve consistent and smooth motion in any supported application.

Applications for 5mm linear bearing shaft

The 5 mm linear bearing shaft is an excellent choice for designers and engineers developing compact automation systems and light-duty linear motion assemblies. Typical applications include:

• Test rigs and inspection systems
• Benchtop scientific and medical instruments
• Lightweight pick-and-place mechanisms
• Small-format 3D printers and CNC equipment
• Precision measuring devices

Its finely ground surface and hardened exterior provide excellent resistance to wear, scoring, and deformation, even when used with recirculating ball bushings or under continuous motion.

This makes it highly suitable for applications where durability and repeatability are essential.

Custom Lengths for Easy Integration

Every 5mm linear bearing shaft is cut to the customer’s required length, accurate to ±0.1 mm. This allows for easy integration into custom machine builds and linear assemblies.

Whether you need a single shaft or a batch for production use, Kiwi Motion delivers shafts ready to install.

Compatible with Kiwi Motion’s Bearings and Supports

The KM-W-5 shaft is fully compatible with Kiwi Motion’s extensive range of linear bearings.

This ensures a perfect match between shaft and support components, making it easier to design systems that maintain long-term precision and reliability.

For precision linear motion in small and lightweight assemblies, the KM-W-5 offers outstanding performance, durability, and value.
