As a specialized manufacturer of high-performance hydraulic components, we deliver precision-engineered Double-Acting Cylinder Piston Rods designed to excel in demanding applications worldwide. Our products, including Hydraulic Piston Rods, Precision Chrome Plated Steel Bars, Hollow Piston Rods, and Hard Chrome Plated Piston Rods, are crafted to meet rigorous international standards. With a focus on durability, efficiency, and innovation, our solutions empower industries requiring reliable linear motion systems.
A Double-Acting Cylinder Piston Rod operates under hydraulic pressure in both directions (extension and retraction), delivering force efficiently without relying on external mechanisms. This design ensures consistent performance in dynamic environments, making it ideal for applications requiring bidirectional force, precise control, and high load-bearing capacity. Our rods are manufactured to minimize friction, reduce wear, and enhance overall system longevity.
Our Double-Acting Cylinder Piston Rods are widely used in:
Industrial Machinery: Presses, injection molding equipment, and automation systems.
Mobile Equipment: Excavators, loaders, and forklifts where bidirectional force is critical.
Heavy-Duty Systems: Mining and construction machinery requiring high load capacity and reliability.
Marine and Aerospace: Steering mechanisms and landing gear demanding corrosion resistance and precision.
Bidirectional Efficiency: Generate force in both directions, eliminating the need for springs or external forces and ensuring smoother operations.
Superior Material Integrity: Forged from high-strength alloys (e.g., 42CrMo4, 316 stainless steel) for exceptional toughness and fatigue resistance.
Advanced Surface Treatments: Hard chrome plating (20–40μm thickness) provides corrosion resistance, reduces friction, and achieves surface hardness of HRC 60–65.
Customization Options: Tailored dimensions (diameters: 10mm–500mm; lengths: up to 12m), coatings (e.g., nickel, ceramic), and configurations (solid or hollow).
Seal Compatibility: Precision-polished surface (Ra ≤ 0.1μm) minimizes seal wear and prevents fluid leakage, compatible with Parker, NOK, and SKF seals.
Technical Expertise: Decades of R&D focus on double-acting technology, supported by ISO 9001 certification.
Rigorous Quality Control: Each rod undergoes pressure testing (up to 500 bar), torsion resistance checks, and salt spray testing (500+ hours).
Global Compliance: Products adhere to ASTM, DIN, and ISO standards, ensuring suitability for international markets.
End-to-End Support: From custom design to after-sales service, we provide comprehensive solutions tailored to your needs.
