💡 Why are hardened and chrome plated linear shafts used in precision linear motion systems?
Hardened linear shafts with chrome plating are built to deliver smooth motion, long life, and consistent accuracy under load.

• High surface hardness reduces wear from linear bearings and bushings

• Chrome plating improves corrosion resistance and surface smoothness

• Tight straightness control supports accurate, repeatable movement

• Common in CNC, automation, and guided linear slide applications

This 20mm linear shaft delivers smooth travel and solid durability, making it a dependable choice when precision motion and long-term performance really matter.
