Precision-Honed Hydraulic Cylinder Tubes: The Core of Reliability

At Changzhou Haorong Hydraulic Equipment Co., Ltd, we specialize in the manufacture of premium Cold Drawn Seamless (CDS) Hydraulic Cylinder Tubes. As a leading factory, we understand that the cylinder tube is the heart of any hydraulic system, and we are dedicated to producing robust, precision-engineered components that global industries depend on.

Engineered for Excellence in Critical Applications

Our hydraulic cylinder tubes are designed to perform under extreme pressure, providing the essential strength and durability required for:

• Construction & Mining Equipment: Excavators, bulldozers, loaders.

• Agricultural Machinery: Tractors, combines, balers.

• Industrial Machinery: Injection molding machines, metal presses, stamping equipment.

• Material Handling: Forklifts, garbage trucks, hydraulic lifts.

Our Manufacturing Commitment: Quality & Precision

We ensure every tube meets the highest international standards through a controlled manufacturing process:

1. Superior Raw Materials: Certified seamless steel billets ensure structural integrity and pressure containment without weak points.

2. Cold Drawing Process: Enhances mechanical properties, achieves precise tolerances, and improves surface finish.

3. Precision Honing: State-of-the-art honing delivers optimal internal surface finish (controlled Ra values) to maximize seal life, minimize friction, and prevent leaks.

4. Rigorous Quality Assurance: Our in-house lab verifies every critical parameter:

   ·Dimensional accuracy (OD, ID, wall thickness).

   ·Surface roughness analysis.

   ·Hardness and hydrostatic pressure testing.

   ·Straightness inspection.
