Import Carrying Roller Group — Buy in wholesale FOB from Supplier in China

The Carrying Roller Group is a set of conveyor rollers engineered for industrial material handling systems, designed to support belts and facilitate smooth movement of bulk materials or unit loads. Each roller in the group is built with industrial-grade steel housings, precision bearings and sealed end caps to resist dust and moisture, with typical diameters ranging from 50 mm to 219 mm and face lengths from 200 mm to 2,400 mm for standard conveyor widths. These rollers integrate directly into troughing or flat belt conveyors in mining, ports and heavy manufacturing environments.

Material composition includes carbon steel tubes (Q235 or Q345 standard) with surface treatments such as galvanisation or rubber lagging for corrosion resistance and grip, while bearings are typically 6204 or 6305 deep-groove ball types with grease-lubricated seals. The group is supplied as a matched set for a conveyor section, ensuring consistent load distribution and alignment, with typical dynamic load ratings between 20 kN and 80 kN depending on shaft diameter and wall thickness. Industry standards often require rollers to meet ISO 1536 for dimensional tolerances and ISO 281 for bearing life calculations.

Primary buyers include bulk material handlers in coal, iron ore and grain terminals, as well as logistics centres moving packaged goods. The supplier offers flexible trade terms for bulk orders, with packaging typically in steel crates or palletised bundles to prevent transit damage. Conveyor systems using these roller groups achieve operational efficiencies by reducing belt wear and energy consumption, provided the rollers are maintained to manufacturer torque and lubrication schedules.

Qingdao Rensheng Huida Trading Co., Ltd. operates from Room 4003, Block B, 226 Mid Changjiang Road in Qingdao, Shandong Province, China, positioned near major ports to facilitate bulk exports. The company is classified as an importer-tier supplier with a harbor trust tier, indicating a focus on international trade logistics and compliance with export procedures. Its profile shows no recorded response rate or average response time, suggesting a preference for direct inquiries via established trade channels rather than digital messaging.

The supplier specialises in conveyor components, including roller groups, idlers and pulleys, catering to industries with heavy-duty material handling needs. While the listing does not specify certifications or production capacity, the product range aligns with standard industrial conveyor system requirements. Buyers are advised to confirm manufacturing accreditations, quality control processes and lead times directly with the supplier, as these details are not publicly disclosed.
