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 significant loads must be driven at moderate speeds, such as in mills, heavy-duty conveyors or process machinery. DONGHUA is a brand offered by MR, and this chain is identified by code ASA 140/3 for replacement or new projects.

This item is a roller chain from the ASA series, designation ASA 140/3. Its main attributes are: 44.45 mm pitch, 25.4 mm roller diameter and 25.4 mm inner width. The 140/3 designation indicates the size and that it is a triple chain, i.e., three strands, which multiplies the load capacity compared with a single-strand chain. It is manufactured under the ASA/ANSI standard, which facilitates interchangeability with sprockets and other components of the same standard.

Typical applications for an ASA 140/3 chain include primary drives in mills, bucket elevators, drag conveyors, rotary kiln drives and heavy machinery in general. Because of its three-strand construction, it is chosen when the torque to be transmitted is high and the space available for chain width is limited. It is also used in equipment where the load is distributed among several strands to extend the service life of the assembly.

To install an ASA 140/3 chain, check that the sprockets have the correct pitch and the right number of teeth for the desired transmission ratio. It is important to align the shafts properly and maintain the correct tension: a chain that is too tight accelerates wear on rollers and bushings, and one that is too loose can jump off the sprocket. Lubricate with oil or grease compatible with the speed and operating temperature. If the application is critical, consult the manufacturer's data sheet to verify service factors and estimated service life.

If you need an equivalent chain or a nearby size, the most practical thing is to send us the complete code ASA 140/3 or the pitch and number of strands required by your equipment. With that data we can offer alternatives from the same series or with similar characteristics. We can also help you identify the chain from a sample or from the sprocket dimensions. At MR Accesorios Industriales we work with in-house manufacturing to give you a reliable solution.
