Precision-Engineered Hydraulic Cylinder Tubes for Demanding Applications

At Changzhou Haorong Hydraulic Equipment Co., Ltd, we specialize in the production of high-precision hydraulic cylinder tubes, engineered to meet the most demanding industrial requirements. Each tube is manufactured from premium high-strength steel supplied by Jiangsu Shagang Group – Huai Steel Special Steel Co., Ltd., ensuring outstanding durability, tensile strength, and structural integrity.

Advanced Manufacturing Process

Our production process combines cutting-edge technology with strict quality standards to guarantee consistent performance and precision:

• Cold Drawing / Hot Rolling – Enhances density and eliminates internal stress for superior strength.

• Precision Honing & Grinding – Achieves tight tolerances (H8/H9) and mirror-smooth surface finishes (Ra ≤ 0.2μm).

• Heat & Surface Treatments – Optional phosphating, nitriding, or electroplating extend corrosion and wear resistance.

• Rigorous Testing – Every tube undergoes ultrasonic inspection, hydraulic pressure testing, and dimensional verification.

Guaranteed Quality, Built for Performance

By integrating strict process control and GMP-level quality management, Haorong ensures that every hydraulic cylinder tube delivers leak-free performance, low friction, and maximum reliability in hydraulic systems.

Applications

Our hydraulic cylinder tubes are trusted in construction machinery, mining, marine engineering, energy, aerospace, and agricultural equipment — where precision and durability are critical to system performance.
