Hollow Chrome Rod/Bar

BOS Hydraulic's hollow chrome plated rods represent advanced engineering solutions combining structural efficiency with superior surface technology. Manufactured through precisely controlled cold drawing or hot rolling processes and finished with a hard chrome plating (thickness: 5-30μm), these high-precision, lightweight components are specifically engineered for high-strength, wear-resistant applications across hydraulic systems, automation equipment, and engineering machinery.

    • Exceptional Strength-to-Weight Ratio: These rods deliver outstanding mechanical strength while significantly reducing component weight, making them ideally suited for applications where minimizing overall system mass is critical without compromising structural integrity.
    • Superior Torsion Resistance: Engineered to withstand substantial torsional forces, our hollow chrome rods maintain dimensional stability under high torque conditions, ensuring reliable performance in demanding power transmission applications.
    • Premium Surface Characteristics: With an exceptionally smooth surface finish (Ra≤0.4μm), these rods minimize friction coefficients, enhance operational smoothness, and provide superior wear resistance, collectively contributing to extended service life and improved system efficiency.
