For heavy-duty power transmission, the DONGHUA ASA 140/2 roller chain delivers reliable performance in demanding environments. As a double-strand chain, it handles high loads while maintaining a compact profile. MR Industrial Accessories supplies this chain along with compatible sprockets and accessories to complete your drive system.
The ASA 140/2 is a double-strand roller chain from DONGHUA. Its designation follows the American Standard: a 44.45 mm pitch, 25.4 mm roller diameter, and 25.4 mm inner width. The "/2" indicates two parallel strands sharing the same pins, which increases pulling capacity without doubling the overall width. This chain is dimensionally equivalent to the ISO 28B series.
Typical uses include main drives in mills, crushers, bucket elevators, drag conveyors, and mining or cement equipment. It also appears in sugar processing and aggregate plants. These settings often involve outdoor or dusty conditions, so periodic lubrication and precise sprocket alignment are essential for long service life.
When selecting this chain, consider sprocket tooth count, center distance, and the power to be transmitted. The double-strand design allows you to reduce pitch or strand count when space is tight, but it requires double-row sprockets. Confirm that shafts and bearings can withstand the radial loads generated by a chain of this size.
