The ASA 140/3 chain is a roller chain with a pitch of 44.45 mm, a roller diameter of 25.4 mm, and an inside width of 25.4 mm. It is used in power transmissions where high loads must be withstood and synchronization between shafts maintained, such as in mills, elevators, and heavy conveyors. SC is a brand that MR sells, and this part number is requested on WhatsApp by indicating the complete designation.

This item is a roller chain from the ASA series, designation ASA 140/3. Its published dimensions are: pitch of 44.45 mm, roller diameter of 25.4 mm, and inside width of 25.4 mm. The ASA series is identified by the pitch in eighths of an inch, and the /3 suffix indicates a triple chain, meaning three rows of rollers in parallel. To confirm the number of rows and the exact pitch, it is always advisable to cross-check the designation with the manufacturer's data sheet.

ASA 140/3 chains are chosen for low-speed, high-torque drives: mills, bucket elevators, drag conveyors, roller tables, and mining or cement equipment. They also appear in old machines or machines of U.S. origin where inch pitch is the standard. Being triple, it distributes the load among three rows and allows the use of smaller sprockets than with a single chain for the same power.

To select correctly, take into account the power to transmit, the speed of the fast shaft, the number of teeth on the sprocket, and the type of lubrication. The triple chain requires three-row sprockets and careful alignment: any misalignment accelerates wear on the rollers and bushings. Also check the tension and the condition of the sprockets; a new chain on worn sprockets stretches prematurely.

If you need a nearby size or an equivalent, send us part number ASA 140/3 together with the pitch, roller diameter, and inside width shown on your equipment. With that data we can verify whether there is a chain from the same series with a different number of rows or whether it is advisable to switch to a metric-pitch chain. We can also advise you on compatible sprockets and assembly tools.
