The ASA 140/3 chain is a roller chain with a 44.45 mm pitch, 25.4 mm roller diameter and 25.4 mm inner width. 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 code is requested on WhatsApp indicating the full designation.

This item is a roller chain of the ASA series, designation ASA 140/3. Its published measurements are: 44.45 mm pitch, 25.4 mm roller diameter and 25.4 mm inner width. The ASA series is identified by the pitch in eighths of an inch, and the suffix /3 indicates triple chain, that is, 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 or US-origin machines where the 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 be transmitted, 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 an equivalent, send us the code ASA 140/3 along with the pitch, roller diameter and inner width shown on your equipment. With that data we can propose the chain of the same series with a different number of rows or, if better, a metric pitch one. We can also guide you on compatible sprockets and mounting tools.
