For drives that need to handle heavy loads across two parallel shafts, the DONGHUA ASA 100/2 roller chain is a double-strand solution built to ASA/ANSI dimensions. Its carbon steel construction and heat-treated components make it a common choice for continuous-duty equipment. MR Industrial Accessories supplies this chain as part of its power transmission range and can help you match it to your application.
The ASA 100/2 code tells you the key dimensions: a 31.75 mm (1 1/4 inch) pitch, a 19.05 mm roller diameter, and a 19.05 mm inside width. The '2' at the end means the chain has two strands running side by side, so it can carry more load than a single-strand chain of the same pitch. DONGHUA produces it to the ASA/ANSI standard, with carbon steel plates and case-hardened pins to resist wear and fatigue.
You will find this chain in main drives for belt and roller conveyors, bucket elevators, mill drives, mixers, compressors, and other heavy machinery. It also suits setups where two shafts must stay synchronized in a tight space. Because of the double-strand design, it is often used where torque and load are high, as long as the sprockets match the pitch and strand count.
When installing an ASA 100/2 chain, pay attention to sprocket alignment, tension, and lubrication. Too much tension speeds up wear on rollers and bushings; too little causes jumping and noise. Use sprockets with the same pitch and two rows of teeth, and keep those rows aligned so both strands share the load evenly. Check elongation regularly to decide when replacement is needed.
If you are looking for an equivalent, send us the code ASA 100/2 or the dimensions of your current chain (pitch, roller diameter, and inside width). We review options within the same series or from other brands we carry, always sticking to the technical specs. We can also recommend compatible sprockets and mounting accessories.

Frequently asked questions
- What does the ASA 100/2 designation mean?
- It refers to an ASA/ANSI roller chain with a 31.75 mm pitch and two strands. The '100' is the pitch size in eighths of an inch (100/8 = 12.5 eighths = 1 1/4 inches), and the '2' indicates double-strand construction.
- Which sprockets work with this chain?
- You need sprockets with a 31.75 mm pitch and a double-strand design, meaning two aligned rows of teeth. The number of teeth depends on your transmission ratio and available space. We can help you choose the right sprocket.
- How can I tell if the chain is worn out?
- Measure elongation: when the chain stretches past the allowable limit, the rollers and bushings have lost material. A quick check is to try pulling the chain away from the sprocket at the engagement area; if it lifts too much, it should be replaced.
