Introduction
The surface of 40Cr Hydraulic Piston Rod has been specially polished, treated with hard chrome plating, and then mirror polished. It has the characteristics of friction resistance and corrosion resistance. The overall structure is simple, easy to install and maintain, and can be widely used in a variety of equipment.
