Hengxin Chain is a specialized chain product line under Qingdao Hengxin Transmission. It focuses on the supply, selection support, and non-standard customization of industrial chains and related transmission components. The product range includes standard roller chains, heavy-duty drive chains, double-pitch conveyor chains, hollow pin chains, leaf chains, agricultural chains, stainless steel chains, and matched sprockets. In addition, custom chains can be manufactured according to customer drawings or field measurements, including special pitch, pin diameter, plate thickness, attachment types, and corrosion-resistant coatings.

Main Product Categories and Selection Considerations

• Drive chains: used for power transmission between shafts, available in single-strand, double-strand, and heavy-duty series.
• Conveyor chains: used for material handling, including double-pitch chains, hollow pin chains, and chains with welded or bolted attachments.
• Agricultural chains: suitable for harvesters, planters, balers, and other farm equipment under dusty and impact conditions.
• Stainless steel chains: suitable for food, beverage, pharmaceutical, and chemical environments where cleaning and corrosion resistance are required.
• Matching sprockets and accessories: supplied as standard plate wheels, finished bore sprockets, taper bushing sprockets, and custom machined versions.

In selection, key parameters include transmitted power, speed, number of teeth, center distance, working environment, load type, and daily running hours. Hengxin Chain supports service factor calculation and chain length verification to prevent premature wear caused by undersizing or excessive tension. For conveyor applications, attachment spacing and guide rail compatibility are also reviewed.

Quality Control and Materials

Common chain materials include medium carbon steel, alloy steel, and stainless steel. Depending on the application, plates, pins, bushings, and rollers undergo heat treatment such as quenching, tempering, or carburizing to improve hardness, fatigue resistance, and wear life. Key inspection items include dimensional accuracy, pin hardness, plate hardness, tensile strength, preload elongation, and surface finish. For high-speed or high-load applications, pre-stretched chains are recommended to reduce initial elongation and maintain stable operation.

Applications

Hengxin Chain products are widely used in:

• Logistics and conveying systems, including roller conveyors, chain conveyors, and lifting platforms.
• Food and packaging lines, with stainless steel and cleanable designs.
• Agricultural machinery, such as combine harvesters, planters, and feed conveying equipment.
• Mining and construction machinery, where heavy load, dust, and shock conditions require high-strength chains.
• General manufacturing, including woodworking, textile, printing, and assembly automation.

Service and Support

Hengxin Chain provides technical selection support, CAD drawings for custom sprockets and attachments, installation guidance, fault analysis, and quick replacement recommendations. For continuous production users, common chain models can be stocked to shorten downtime. The product line also supports integrated drive solutions with speed reducers and couplings from Qingdao Hengxin Transmission, helping customers coordinate chain transmission with motor and gearbox selection.
