Chrome plated Stainless Steel Linear Shafts Induction Hardened – Introduction

Chrome plated Stainless Steel linear shafts induction hardened are a very special type of products. The stainless steel used to manufacture this type of product is: X46Cr13. Induction hardening 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.

Induction hardened linear shafts 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.

The chrome surface of our Chrome plated stainless steel linear shafts is giving good wear and corrosion resistance. The chroming process is giving also a good durability and helps diminishing friction.

We recommend our Chrome plated stainless steel linear shafts for more complex applications.

Packaging A-LINE WRBV are supplied in 3 different packaging options:

  • Standard packaging is made from plastic sleeves or paper tubes (depending on the product’s diameter).

  • Special Packaging (seaworthy protected) with additional cost is made with aluminum foil or vacuum bags.

As an Extra protection with additional cost we are providing also wooden boxes.

Marking in ASO HYDRAULICS & PNEUMATICS has a full trace-ability.

Each bar is marked individually on the plastic/paper tube with info about the date, product series, diameter, tolerance, resistance at saltwater spray test, heat no, production order and so on. The batch has a label with information regarding: Order no, Item no, Heat no., Steel Grade; total length of the batch, Weight, no of pieces in the batch.

A-LINE WRBV chrome plated stainless linear shafts are delivered having the Rod end painted green with a yellow line.
