Precision CNC-Machined Hydraulic Piston Rod – Forged Steel Construction with Hard Chrome Plating

Product Overview
Our premium hydraulic piston rods are precision-engineered from grade 4140 forged steel and finished with hard chrome plating for exceptional durability in demanding industrial applications. Manufactured with ±0.01mm straightness tolerance and mirror-like surface finish (Ra 0.2μm), these rods ensure leak-proof performance in hydraulic cylinders.

Key Features & Specifications
✓ Material: High-strength 4140 forged steel, heat-treated to 28-32 HRC hardness
✓ Machining: Precision CNC turning and grinding for dimensional accuracy (±0.01mm)
✓ Surface Treatment: 50μm hard chrome plating exceeds ISO 6158 standards
✓ Surface Finish: Ultra-smooth Ra 0.2μm finish for optimal seal performance
✓ Applications: Hydraulic presses, construction equipment, agricultural machinery, and industrial automation systems

Technical Advantages
• Superior Wear Resistance: Hard chrome plating provides 3x longer service life than standard rods
• Precision Fit: CNC-ground to exact tolerances for perfect seal compatibility
