The SC ASA 140/3 is a triple-strand roller chain built for power transmission drives that demand high load capacity and reliable shaft synchronization. It features a 44.45 mm pitch, a 25.4 mm roller diameter, and a 25.4 mm inner width. Typical applications include mills, elevators, and heavy conveyors. MR supplies this chain, and you can request a quote by sending the full designation via WhatsApp.

This chain belongs to the ASA series and carries the designation ASA 140/3. Its published dimensions are: pitch 44.45 mm, roller diameter 25.4 mm, and inner width 25.4 mm. In the ASA system, the pitch is expressed in eighths of an inch, while the /3 suffix denotes a triple chain—three parallel rows of rollers. Always cross-check the designation against the manufacturer's data sheet to confirm the number of rows and the exact pitch.

ASA 140/3 chains are typically selected for low-speed, high-torque drives such as mills, bucket elevators, drag conveyors, roller tables, and equipment in mining or cement operations. They also appear in older or US-origin machinery where inch pitch is standard. Because it is triple-strand, the load is distributed across three rows, allowing the use of smaller sprockets than a single-strand chain for the same power.

When selecting this chain, consider the power to be transmitted, the speed of the fast shaft, the number of teeth on the sprocket, and the lubrication method. A triple chain requires three-row sprockets and precise alignment; misalignment accelerates wear on rollers and bushings. Also check chain tension and sprocket condition—a new chain running on worn sprockets will stretch prematurely.

If you need an equivalent, send the code ASA 140/3 along with the pitch, roller diameter, and inner width from your equipment. With that information, we can propose a chain of the same series with a different number of rows or, if more suitable, a metric-pitch alternative. We can also advise on compatible sprockets and mounting tools.

To request a quote for this SC ASA 140/3 chain, message us on WhatsApp at MR with the designation and the quantity you need. If you are unsure about the series or suffix, send a photo of the old chain or sprocket and we will review it. Accurate data helps prevent downtime.
