Chrome Plated Hollow Linear Shafts – Introduction

Chrome plated hollow linear shafts made from C60 steel.

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.

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

Chrome Plated Hollow Linear Shafts – Technical Properties.

  • Diameter Tolerance Standard for linear shafts is ISO-h7. We can also provide special tolerance at premium price.

  • Length tolerance: 0/+200 [mm].

  • Surface Roughness isRa = max 0.20 µm.

  • Chrome Layer Surface Hardness is minimum 900 HV 0,1.

  • Surface HardnessSteel-grade C60 IH: 62+2HRC.

  • Chrome Layer thickness is minimum 10[µm], usually 15[µm].

For chrome plated hollow linear shafts we can provide special chrome layer thickness at premium price.

Packaging A-LINE WV 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 can provide also wooden boxes.

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

Each chrome plated hollow linear shaft 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.
