The Induction Hard Chrome Plated Piston Rod is a core component widely used in hydraulic cylinders, pneumatic equipment, and heavy-duty machinery. With advanced induction hardening treatment and precision chrome plating, the piston rod delivers outstanding wear resistance, smooth surface performance, and high load-bearing capacity.

At Wuxi Shenlu Hydraulic Machine Parts Co., Ltd., we specialize in manufacturing high-precision piston rods with strict dimensional tolerances and superior hardness. For higher durability, our Induction Hardened with QT Piston Rods undergo both induction hardening and quenching-tempering, ensuring excellent toughness, stability, and extended service life in demanding environments. Looking for reliable piston rods for your hydraulic system? Send us your inquiry today!

 

 

Outstanding Surface Hardness – Induction hardening increases wear resistance significantly.

High Corrosion Protection-Chrome-plated surface offers superior anti-rust performance.

Excellent Fatigue Strength – The QT process ensures superior resistance under cyclic loads.

Smooth Surface Finish-Minimizes friction, ensures sealing efficiency, and prolongs service life.

Precision Machining – Tight tolerance control for hydraulic cylinder applications.

Customizable Options-Flexible dimensions, finishes, and treatments available.
