When a drive needs extra capacity without stepping up to a larger pitch, a three-strand roller chain is often the answer. The DONGHUA ASA 50/3 delivers that: a 15.87 mm (5/8") pitch, a 10.16 mm roller diameter, and a 9.53 mm inner width. Because it follows the ASA/ANSI standard, its dimensions interchange with other brands built to the same specification. MR supplies this chain and can help you match it to your sprockets and center distance.

Reading the code helps with selection. The 50 identifies the pitch under the ASA/ANSI system; the /3 tells you there are three parallel strands of rollers linked by common pins. That construction spreads the load across three times the width of a single-strand chain of the same pitch, so you get more pulling capacity in the same footprint. The chain is made of steel and is intended for power transmission in machinery.

Where does a chain like this fit? Think of main drives on machine tools, belt or roller conveyors, pump and compressor drives, and lifting equipment that needs multiple strands to share the load. You will also find it in food, wood, and ceramics operations, as long as the setting is not heavily corrosive or abrasive. It suits equipment where space is tight and higher torque must be transmitted without increasing pitch.

Installation and upkeep matter. Confirm that your sprockets are triple-strand and properly aligned before fitting the chain. Lubricate with a product made for roller chains, and check elongation at regular intervals. When selecting, weigh the power to be transmitted, the shaft speed, and the number of sprocket teeth. In dusty or damp conditions, consider an anti-corrosion chain or an automatic lubrication system.

If your application calls for a 12.7 mm pitch (ASA 40), a 19.05 mm pitch (ASA 60), or a double-strand version (ASA 50/2), we can help you find an equivalent. We can also quote a specific length or a pin link. Send the code ASA 50/3, or the pitch and strand count you need, and we will come back with options.

To request a quote, message us on WhatsApp or email with the code DONGHUA-ASA-50-3 or the designation ASA 50/3. Include your sprocket data and center distance if you want us to check compatibility. Our team replies promptly and can suggest equivalents or help you choose the right chain.
