Import Agricultural Chain — Buy in Bulk from Supplier in China

Hangzhou Donghua Chain General Factory produces agricultural chains in models S32, S42, S45, S52, S55, S62, S77, S88, CA550, CA555, CA620, and CA650, designed for use in farming machinery such as harvesters, balers, and conveyors. These chains are manufactured from industrial-grade steel, with precision engineering to ensure consistent performance under heavy loads and abrasive conditions typical in agricultural environments.

The chains feature high tensile strength, with standard breaking loads ranging from 15 kN for lighter models like S32 to over 100 kN for heavy-duty variants such as CA650. Typical pitch sizes span 31.75 mm to 76.2 mm, with roller diameters and inner widths matched to ISO 487 or ANSI B29.1 standards. Surface treatments often include shot peening or zinc plating to enhance wear resistance and corrosion protection in outdoor applications.

Primary buyers include agricultural equipment manufacturers, large farms, and OEMs in Asia, Europe, and the Americas. The chains are compatible with machinery from brands like John Deere, New Holland, and Kubota, with standard attachment styles (e.g., C-type, K-type) for easy integration. Buyers commonly confirm compatibility with their machinery’s sprocket specifications and request samples for field testing before bulk orders.

Hangzhou Donghua Chain General Factory is based in No. 218 Jichang Road, Hangzhou, Zhejiang Province, China, and specializes in the manufacture of agricultural chains for machinery applications. The factory’s product range includes over a dozen models, each designed to meet the demands of modern farming equipment, with a focus on durability and precision engineering.

The supplier’s profile classifies it as an imported tier with a harbor trust tier, indicating a baseline level of verification. While the listing does not provide response metrics or client details, the emphasis on adherence to international standards (e.g., ISO, ANSI) and the breadth of model compatibility suggest a supplier capable of meeting OEM and aftermarket requirements for agricultural chains.
