For power transmission between parallel shafts, the DONGHUA ASA 120/2 roller chain is a standard, replaceable component. It has a 38.1 mm pitch, a 22.23 mm roller diameter and a 25.4 mm inner width. As a single-strand chain in the ASA series, it is easy to source and install.

The designation ASA 120/2 tells you what you are holding: a single-strand roller chain from the ASA series. The 120 indicates the size, and the /2 confirms one row of rollers. Key dimensions are pitch 38.1 mm, roller diameter 22.23 mm and inner width 25.4 mm. DONGHUA produces this chain within its ASA line, so it interchanges with other standard components in the same series.

You will find this chain in agricultural machinery, conveyors, elevators, mining equipment and plant drive systems. Its pitch and construction suit moderate torque at higher speeds when mounting and lubrication are correct. It also works as a replacement on production lines where uptime matters.

Before ordering, confirm the pitch matches your sprockets (38.1 mm) and that the inner width fits. Check shaft alignment, tension and the lubricant recommended for the application. In dusty or humid areas, use guards or a suitable lubricant. Standard links and accessories from the ASA series simplify assembly.
