When a drive runs at low speed but has to move serious tonnage, the chain is usually where the whole job rests. The DONGHUA ASA 200/3 is a triple-strand roller chain built for that kind of duty, with a 63.5 mm pitch, a 39.68 mm roller diameter and a 38.1 mm inner width. MR supplies this chain and can help you work out the length you need and the sprockets that go with it.
Reading the designation is the quickest way to know what you are ordering. ASA 200 sets the pitch at 63.5 mm, and the 200 number follows the ASA/ANSI numbering system, so a chain carrying that designation from any maker should interchange as long as the roller diameter and inner width match the figures above. The /3 is the part that changes the selection: it means three strands running side by side, which is how this chain handles heavy pulling loads that a single strand of the same pitch could not.
You will run into this size in equipment where the shafts sit far apart and speed stays low: mills, crushers, bucket elevators, drag conveyors, kiln drives, and mining or cement machinery. It also turns up on older or oversized machines where the original drive was built around a wide center distance and a chain that can take punishment at low rpm with the right lubrication.
Sizing starts with three inputs: the power the drive has to transmit, the speed of the shaft, and the tooth count on the sprocket. A triple chain only works with triple-strand sprockets matched to the same pitch and inner width, so the sprocket has to be part of the conversation. On the installation side, check that the shafts are aligned, that tension is set correctly, and that the lubrication method suits the load. The heavier the duty, the more the roller and bushing depend on a continuous oil film between them.
If you are replacing a chain rather than building a new drive, measure the pitch and the inner width before you order, and note how many strands the old chain had. A photo of the chain and the sprocket helps confirm what you are dealing with, and the brand and model of the machine narrows it down further.
Send the complete part number, the number of rows, the pitch and any photos through WhatsApp, and MR will review options in DONGHUA as well as equivalents from the other brands we carry. If the drive is new, tell us the application and we can help you settle on length and sprocket pairing.

Frequently asked questions
- What does the /3 in ASA 200/3 tell me?
- It identifies a triple-strand chain: three rows of rollers working in parallel. That configuration carries more pulling load than a single or double strand at the same pitch. Installation requires triple-strand sprockets cut for this pitch and inner width.
- Can a chain from another maker replace this one?
- It can, provided the replacement follows the ASA/ANSI standard and matches the pitch, roller diameter and inner width listed here. DONGHUA is one of the brands MR supplies, and we can also check equivalents from other lines. Send the part number and dimensions and we will confirm what fits.
- What information do you need to quote a size?
- The part number, strand count, pitch, and a photo of the chain or sprocket are the essentials. From there we can locate a size within the ASA series or an equivalent from another brand. The more detail you send, the quicker we can come back with an option.
