Induction Hardened Linear Shafts – Introduction

Induction hardened linear shafts made from 1024 steel.

Hardening through induction is a form of heat treatment in which the linear shafts are heated by induction heating and then quenched. This heat treatment is increasing the hardness as well as the brittleness of the linear shafts.

Linear shafts that are hardened through induction present a soft shaft core which ensures a good resilience. Linear Shafts may appear the same for an untrained eye but the differences are notable. There are significant performance differences due to the manufacturing processes used to achieve the required standards. The linear inner race demands the highest levels of material cleanliness, surface topography, surface hardening, diameter, taper and roundness, surface finish and straightness in order to provide optimum performance at minimal maintenance and long life.

A-Line WZ Linear shafts are used as piston rods for pneumatic cylinders as well as in all linear applications.

Linear Shafts – Technical Properties.

  • Diameter Tolerance Standard for linear shafts is Class „L”. We can also provide special tolerance at premium price.

  • Length tolerance:  0/+8 [in]; 0/+200 [mm].

  • Surface Roughness isRa = max 0.20 µm.

  • Surface Hardness: Steel-grade 1024 (Cf53) IH: 62+2HRC.

Packaging Linear shafts are degreased and oiled, placed in bundles that are wrapped in wax paper and raffia.As an Extra protection with additional cost we can provide also wooden boxes.

SubtitleMarking in ASO HYDRAULICS & PNEUMATICS has a full traceability.

Each batch has a label that contains info about: manufacturing date, product name, diameter, tolerance range, number of linear shafts, heat no.

A-LINE WZ induction hardened linear shafts are delivered having the Rod end painted in yellow with white line.
