Premium Honed Tubes by Jiangyin Carridea Technology: Precision Redefined for Hydraulic Excellence

Jiangyin Carridea Technology Co., Ltd. is a distinguished manufacturer and supplier of high-quality honed tubes, located in Jiangyin, Jiangsu Province, within the Yangtze River Delta. With 18 years of dedication to researching, developing, and producing precision steel tubes, we have become a global trusted partner, renowned for quality, technological innovation, and customer-centric solutions. Our honed tubes, also known as hydraulic cylinder tubes, represent precision engineering at its best, designed to meet the strictest demands of modern hydraulic and pneumatic systems.

Since 2008, we have continuously invested in cutting-edge technology and advanced equipment. Our 15,000-square-meter production base houses high-precision cold-drawing hydraulic units (250t and 300t), large-scale honing machines, and 12-meter CNC honing units, enabling an annual production capacity of over 15,000 tons. This ensures efficient fulfillment of both standard and custom orders.

Our team of seasoned engineers optimizes every production process, from raw material selection to final inspection. We strictly follow international standards such as DIN 2391, EN 10305-1, and ASTM A519, with an ISO 9001-certified quality management system, guaranteeing consistent quality.

Superior products start with superior materials. We source raw materials from reputable steel mills, offering honed tubes in high-grade carbon steel (20#, 45#, 16Mn, ST52) and alloy steel (27SiMn, 42CrMo, Q345B) to tailor to specific needs like high pressure and wear resistance.

Quality control is integral to every stage. Each honed tube undergoes a 30-step inspection, including raw material testing, dimensional checks, surface roughness measurement, and non-destructive testing. We guarantee an internal surface roughness of Ra 0.2–0.4 μm and internal diameter tolerances of H7, H8, or H9 for precise fit and performance.

We offer comprehensive standard specifications and full customization: inner diameter 20–600 mm, length 1–12 m (customizable), wall thickness 3–50 mm, and dimensional deviation ±0.05 mm. We accommodate low-volume prototypes to high-volume runs, with a 15-day rapid delivery cycle for custom orders.

Our honed tubes are widely used in construction machinery (excavators, cranes), hydraulic/pneumatic systems, rail transit, mining machinery, agricultural machinery, marine/offshore equipment, and automotive components. They are trusted by industry leaders like Sany Heavy Industry, a testament to their reliability.

Why choose Carridea? We offer 18 years of specialization, advanced manufacturing, rigorous quality assurance, customization flexibility, competitive factory pricing, global supply capability, and exceptional customer service.
