The ASA 200/3 chain is a roller chain with a 63.5 mm pitch, a roller diameter of 39.68 mm and an inner width of 38.1 mm. It is used in heavy-duty power transmissions, where high loads must be pulled at moderate speeds. DONGHUA is a brand that MR carries, with technical support to select the length and compatible sprockets. If you need to replace an existing chain or build a new drive, send us the part number and we'll quote you.

This item is a roller chain from the ASA series, designation ASA 200/3. Its published dimensions are: pitch 63.5 mm, roller diameter 39.68 mm and inner width 38.1 mm. The /3 suffix indicates a triple chain, meaning three rows of rollers in parallel, which multiplies the pulling capacity compared to a single chain of the same pitch. It is manufactured under ASA/ANSI standard, so it is interchangeable with equivalent chains of that standard.

Typical applications of a chain with this pitch and triple row are high-load drives: mills, crushers, bucket elevators, drag conveyors, kiln drives and mining or cement equipment. It also appears in old or large machines where the center distance is wide and a robust chain is needed to work at low speed with proper lubrication.

To properly select the chain, take into account the power to be transmitted, the shaft speed and the number of teeth on the sprocket. A triple chain requires triple-strand sprockets compatible with the same pitch and inner width. Check shaft alignment, correct tension and the type of lubrication: the higher the load, the more important it is to maintain an oil film between roller and bushing. If the drive already exists, measure the pitch and inner width before ordering.

If you can't find the exact size, we can look for an equivalent or a neighboring size within the same ASA series. For that, we need you to send us the complete part number, the number of rows, the pitch and, if possible, a photo of the chain and the sprocket. It also helps if you indicate the brand and model of the equipment where it is mounted. With that data we review alternatives in DONGHUA and in other brands we carry.
