 Linear axis must maintain a high surface hardness (wear resistance), strength and stability of tolerance to be used within the rail axis and the axis. The cylinder rods are widely used in automatic precision printers, automatic cutting machines, and industrial robots and many other linear motion system. 
 Chrome plated linear shaft to increase its anti-corrosion features.
