Company & Product Introduction
JNM Metals Industrial is a professional manufacturer and supplier of premium hard chrome plated piston rods, dedicated to providing high-precision, durable hydraulic components for global industrial clients. We focus on standard and custom piston rods widely applied in hydraulic cylinders, construction machinery, automated equipment and lifting systems. Combining strict material selection, precision machining and standardized surface treatment, our chrome piston rods deliver stable performance, low friction and excellent corrosion resistance, solving common hydraulic system failure issues caused by poor rod precision and insufficient surface protection.
Core Product Advantages
Our premium chrome plated piston rods adopt high-quality carbon steel and alloy steel substrates, with professional quenching and tempering heat treatment to balance hardness and toughness. Strict ISO F7/F8 tolerance control ensures perfect coordination with seals and guide sleeves, avoiding oil leakage and abrasion during high-frequency reciprocating operation. The uniform dense hard chrome plating features ultra-low surface roughness, effectively improving wear resistance, oxidation resistance and salt spray resistance, adapting to harsh working environments of humidity, dust and long-term cyclic load.
