The ASA 100/3 chain is a roller chain with 31.75 mm (1 1/4") pitch, 19.05 mm roller diameter and 19.05 mm inner width. It is used in power transmissions where significant loads must be driven at moderate speeds, such as conveyors, mills, elevators and process machinery. DONGHUA is an official brand carried by MR, with technical support to select the length and compatible sprockets.

This item is a roller chain from the ASA series, designation ASA 100/3. Its listed attributes are: 31.75 mm pitch, 19.05 mm roller diameter and 19.05 mm inner width. The 100 designation corresponds to the pitch in eighths of an inch (100/8 = 12.5 eighths, equivalent to 1 1/4"), and the /3 suffix indicates a triple-strand chain, that is, three rows of rollers in parallel. DONGHUA manufactures it under ASA/ANSI standard, with plates and pins suitable for continuous service.

Typical applications of an ASA 100/3 chain are high-capacity drives: belt and chain conveyor drives, bucket elevators, mills, mixers, woodworking machines and process equipment where high torque must be transmitted with a single chain line. It is also used to replace single- or double-strand chains when more strength is required without changing sprocket diameters, as long as the hub width and housing allow it.

To install and select this chain, verify that the sprockets have a 31.75 mm pitch and the right number of teeth for the desired transmission ratio. The triple-strand chain requires triple-strand sprockets and a compatible hub width. Check shaft alignment, correct tension and lubrication: a poorly tensioned or unlubricated chain stretches and wears prematurely. If space is limited, consider a smaller-pitch chain or a belt drive.

If you need a neighboring size, a different length or an equivalent chain from another brand, send us the part number ASA 100/3 and the number of pitches or the total length in meters. We can also verify compatibility with the sprockets you already have. We work with DONGHUA as an official brand carried by MR, and with in-house manufacturing of split plummer block housings, ANSI roller chains and pulleys (sheaves) when the project requires it.
