In hydraulics, a piston is typically connected to a rod, which extends through a cylinder, to transmit force. The rod needs to be strong enough to withstand the massive forces and stresses during movement.

Chrome is the answer. Chrome rods are typically made from a type of steel that has been plated with a layer of chromium. Why? In short, it’s all about strength, corrosion resistance, and a smooth finish. 

Strength:

Because chrome rods are typically plated with a layer of chromium, they are incredibly strong, extremely hard, and resistant to corrosion – which extends their entire lifespan, ensuring smooth operation for longer.

The hardness of the chrome plating also helps to prevent damage to the rod from contaminants in the hydraulic fluid, such as dirt or debris. This is important because even small amounts of damage to the rod can result in leaks, which, as we know, is bad news.

Corrosion Resistance:

Chrome plating provides excellent resistance against corrosion and oxidation. Hydraulic systems often operate in challenging environments full of moisture, chemicals, and other corrosive elements. Chrome plating helps protect the hydraulic rods from these corrosive agents, ensuring their longevity and reliability.

Wear Resistance:

Chrome plating enhances the wear resistance of hydraulic rods. As the rod moves within the hydraulic cylinder, it experiences friction and wear. The hard chrome surface reduces wear and extends the service life of the hydraulic rod, resulting in less frequent maintenance and replacement.

Smooth Surface Finish:

Chrome plating results in a smooth surface finish, which reduces friction and improves the efficiency of the hydraulic system. A smoother surface also minimises the risk of seal damage and leakage, enhancing the overall performance of the hydraulic cylinder.

Aesthetic Appeal:

Chrome plating gives hydraulic rods a shiny appearance. While aesthetics and being able to do your hair in them may not be the primary consideration in hydraulic systems, it can be a factor, especially in applications where appearance matters.

Overall, chrome-plated hydraulic rods offer a combination of corrosion resistance, wear resistance, and smooth operation, PLUS they look great. Making them the go-to for most hydraulic applications.
