The Donghua ASA 80/H chain is a roller chain with a 25.4 mm (1 in) pitch, a roller diameter of 15.88 mm and an inner width of 15.88 mm. It is used in power transmissions where medium loads must be driven at moderate speeds, with a good balance between strength and weight. It is an ASA series chain, the most widely used in the American market, and Donghua is an official brand that MR offers.

This item is an ASA 80/H ANSI roller chain from the ASA series, manufactured by Donghua. The pitch is 25.4 mm, the roller diameter is 15.88 mm and the inner width is 15.88 mm. The 80/H designation corresponds to size 80 with a wider inner width than the standard 80 chain, which gives it more contact surface with the sprocket. It comes in variable-length sections depending on what you need.

It is used in general power transmission: conveyors, elevators, agricultural machines, bottling equipment, packaging belts and low- and medium-speed drives. Also in applications where the chain works outdoors or with dust, because the larger roller diameter tolerates wear better. It is common in production lines that already have sprockets for 25.4 mm pitch and need to replace the chain without changing the sprockets.

To install an ASA 80/H chain, check that the sprockets are compatible with the 25.4 mm pitch and the 15.88 mm inner width. Check shaft alignment and tension: a chain that is too tight accelerates wear on rollers and bushings, and one that is too loose jumps teeth. Lubricate with chain oil or grease according to the work environment. If the application has impact loads, contact us and we'll help you evaluate whether a higher-strength chain is better.

If you need an equivalent or a neighboring size, send us the ASA 80/H code or the pitch and inner width shown on your current chain. It also helps if you tell us the number of teeth on the sprockets and the center distance. With that data we can offer you the same chain in another brand or an ASA series alternative with the same dimensions. If you don't have the code on hand, a photo of the chain and the sprocket helps a lot.
