The DONGHUA ASA 50/2 is a double-strand roller chain built to the ASA/ANSI standard. With a 15.87 mm pitch, it handles roughly twice the load of a comparable single-strand chain, making it a practical choice when you need more capacity without doubling up on separate drives.

Reading the code helps at the counter: ASA 50/2 combines the 50 size, which sets the 15.87 mm pitch, with the /2 suffix for two strands of rollers running in parallel on the same pins. The roller diameter is 10.16 mm and the inner width is 9.53 mm. Because the chain follows the ASA/ANSI standard, it interchanges with other components in the same series.

Double-strand construction suits drives where a single strand would be marginal: agricultural machinery, conveyors, packaging lines, mixers, gear reducers and lifting mechanisms. It also lets you use one double-strand sprocket instead of two single-strand sprockets side by side, which can simplify the shaft layout.

Installation is straightforward if you check a few points first. Confirm the sprockets are double-strand and match the 15.87 mm pitch, align the shafts, and set proper tension. Lubricate according to the operating regime and check for elongation at regular intervals. When replacing an existing chain, compare pitch, roller diameter and inner width against the original.

If you are cross-referencing, send the ASA 50/2 code or the code of the chain you are replacing, along with the number of strands and the pitch. The team can suggest equivalents within the ASA series and advise on compatible sprockets. Quotes are handled by WhatsApp or email, and replies are prompt.
