For drives that need a steady speed ratio and minimal upkeep, the DONGHUA ASA 415/H roller chain is a practical choice. It follows the ASA series and measures 12.7 mm in pitch, with a roller diameter of 7.77 mm and an inner width of 7.76 mm. MR Industrial Accessories supplies this chain as part of its ASA/ANSI line for customers in the United States and Latin America.

The 415/H designation breaks down into three parts: ASA for the American standard series, 4 for the pitch type and 15 for the size, while the H points to a construction variant. In practice, that H often means thicker plates or a surface treatment, following the usual approach for this series. The chain is manufactured by DONGHUA and is intended for moderate-speed applications where loads can vary.

You will find this chain in agricultural equipment such as seeders and harvesters, as well as in modular belt conveyors, bucket elevators and packaging lines. It also appears in motor-to-gearbox drives where minor misalignment must be absorbed while keeping components synchronized. Its pitch and strength suit equipment running at moderate speeds with changing loads.

When selecting the chain, consider the number of sprocket teeth, the center distance, the power to transmit and the operating environment. Check shaft alignment and tension carefully: too tight and the rollers and sprockets wear faster; too loose and the chain may jump or knock. Lubrication matters as well—oil or grease in clean areas, dry lubrication or guards where dust is present.

If you need a replacement, send the complete part number or the designation from the equipment plate. You can also provide the pitch, sprocket tooth count and total length required. With those details, the MR team can identify the DONGHUA ASA 415/H chain or propose a compatible alternative from the same series. Ask about special sizes or sections with a different number of links.
