KM-W Series

KM-W CF53 Steel Induction Hardened Linear Shaft

The CF53 induction hardened linear shaft, known by Kiwi Motion as KM-W, is the most used and most stocked linear shaft. It offers good resilience capabilities at a very affordable price point and works perfectly in tandem with our linear bearings. With our bespoke machining and cutting facilities and with our unwavering focus on quality, that serves the whole of the UK & Ireland and beyond, you can be sure you will receive only the best linear shaft for your application.

The Process

All our linear shafts are induction hardened which is a type of heat treatment where the shaft is heated via induction heating then followed by quenching. This process allows us to achieve the required high standard of linear shaft than that of other steel rods.

This heat treatment process increases the hardness and brittleness of linear shafts, which in turn means that considerable expertise, know-how, and experience should be used when cutting and machining the linear shaft.

We demand only the very best from our linear shafts and work tirelessly to achieve consistency and top standards. This means the inner race only has the highest levels of straightness, surface hardening, diameter, surface finish and material cleanliness. These stringent controls mean optimum performance with minimal wear, low ongoing maintenance and long life.

Bespoke To Your Requirements

We stock all our linear shafts in standard lengths. This does not mean you have to settle for ‘standard’. All our shafts are available cut to length and custom machined to drawing.
