This item is an ASA 120 roller chain from DONGHUA. Its pitch is 38.1 mm, roller diameter is 22.23 mm, and inside width is 25.4 mm. The ASA series is the American designation for inch-pitch roller chains, and the number 120 indicates the size: the higher the number, the greater the pitch and transmission capacity. It is available in versions with one or more strands—single, double, or triple—depending on the load requirement.

It is used in chain drives for industrial equipment: conveyors, elevators, mills, mixers, construction machinery, agricultural equipment, and transmission systems in process plants. It is common in applications requiring synchronization between shafts and positive drive, without slippage, with good wear and tensile resistance.

To install it, check that the sprockets have the same pitch and are aligned; misalignment accelerates wear on the chain and teeth. Check tension: it should have minimal sag—neither too tight nor too loose. Lubricate with the oil recommended for the speed and load. If the chain operates in a dusty or dirty environment, use suitable lubrication and check wear periodically.

If you need a nearby size or an equivalent, send us the complete code, the number of strands, and the number of links or the total length. With that data we can offer an alternative from the same series or another brand. We can also advise you on compatible sprockets and lubricants for installation.
