Import Best Selling Double Arrow Conveyor Rollers — Buy in Bulk from Supplier in China

Double Arrow Conveyor Machinery Co., Ltd. manufactures conveyor rollers from its base in Jiangsu, China, engineered for bulk material handling across mining, cement, and aggregate processing lines. The rollers feature steel shells with precision-machined bearing housings, designed to accommodate standard CEMA or DIN frame configurations with shaft diameters typically ranging from 20 mm to 40 mm depending on load class. Bearing assemblies use deep-groove or spherical roller bearings, sealed against dust and moisture ingress for extended service intervals in abrasive environments.

Shell thickness varies by specification, with standard carbon steel shells at 3 mm to 4.5 mm for general duty and thicker walled options for heavy-impact loading zones. Surface treatments include hot-dip galvanising or rubber lagging where grip and wear resistance are critical. The bearing cavities are normally filled with lithium-based grease, and labyrinth seals or triple-lip contact seals protect against contamination, a common failure mode in outdoor or unguarded installations. Shaft ends are typically machined to tolerance h6 or h7 for interference fit into the bearing bore, with circlip or locking collar retention.

These rollers integrate into troughed or flat belt conveyors, serving industries where continuous flow of crushed stone, coal, ore, or packaged goods demands reliable idler performance. Buyers include quarry operators, port bulk terminals, and original equipment manufacturers assembling conveyor systems for export. The supplier lists FOB and CIF as available trade terms, though exact freight routing from Jiangsu ports and current lead times should be confirmed directly with Double Arrow Conveyor Machinery Co., Ltd. before placing an order.

Double Arrow Conveyor Machinery Co., Ltd. operates from 7 Kaitai Road in Nanzha Town, Jiangyin City, Jiangsu Province, China, an industrial corridor with established metallurgical and machined-goods supply chains. The supplier carries an imported tier classification and a harbor trust designation, with a response rate currently showing zero percent and no recorded average response hours. These signals indicate limited transactional history visible on the platform, so buyers should initiate direct contact early in the sourcing process to gauge responsiveness and technical support capability.

The listing positions the company as a manufacturer of conveyor rollers for industrial material handling, though it does not disclose factory size, annual output, number of employees, or specific clientele. No ISO certificates, test reports, or third-party audit documentation is referenced in the available data. Buyers evaluating this supplier should request bearing manufacturer certifications, shell material mill certificates, and weld inspection records to verify consistency with stated specifications. The address places production within the Wuxi-Jiangyin manufacturing cluster, where numerous conveyor component producers compete, suggesting buyers can compare against nearby alternatives if initial negotiations stall.
