Customized Hydraulic Cylinder Piston Rod Hard Chrome Plated Rod

Chrome rods are also called Piston rods, hard chrome rods or chrome plated rods. The chrome rod is a component commonly used in internal combustion engines, hydraulic cylinders and other construction machinery. It connects the piston to the external machine, thereby converting the internal fluid pressure into linear motion.

    Product Introduction

    The chrome rod is made of high-quality materials, usually high-strength steel or alloy materials, including CK45 S45C ST52 SAE1045 SAE10V45 42CrMo4 20MnV6. These materials ensure that the piston rod has sufficient strength and rigidity to withstand the working load.

    One of the main features of the chrome rod is its precise surface treatment, which guarantees seamless operation and minimal friction. In order to improve the wear resistance and corrosion resistance, the surface of the chrome rod will be specially treated, such as chrome plating, nickel plating or other coating technologies, usually called chromium plating piston rod, nickel plating piston rod. The rod surface is hard chrome plated, ensuring excellent wear and tear resistance, making it ideal for heavy-duty applications.

    The main purpose of chrome rod chromium plating is to enhance the hardness, wear resistance, temperature resistance and corrosion resistance of the piston rod, thereby improving its overall performance. The thickness of chromium plating is generally controlled above 10-30um. Whether used in hydraulic cylinders, pneumatic cylinders or other mechanical systems, our chrome rods can withstand it, ensuring reliable performance and long service life.
