Hydraulic Cylinder Piston Rod

Product Specification

Feature

Engineered from high-strength carbon, alloy, or stainless steel (45#, 40Cr, 42CrMo4, SUS 304/316), this precision hydraulic piston rod features a massive size spectrum up to $\Phi 1200 \text{ mm}$ in diameter and 10 meters in length. It undergoes rigorous quenching and tempering to achieve an exceptional surface hardness of HRC 50–60, while a $30–50\ \mu\text{m}$ hard chrome plating delivers superior wear and corrosion resistance. With a tight straightness tolerance of $0.015 / 1000 \text{ mm}$ and a mirror finish of $\Delta 0.15–0.2\ \mu\text{m}$, it minimizes friction, protects hydraulic seals, and guarantees long-term, zero-leakage performance across heavy construction, mining, and marine machinery.
