The ASA 140/2 chain is a double-strand roller chain used in power transmissions where a large load must be moved in a small space. Its 44.45 mm pitch and 25.4 mm rollers place it in the heavy chain segment, for equipment that works under demanding conditions and needs a reliable transmission. At MR Accesorios Industriales we sell it as part of our power transmission line, together with sprockets and accessories to assemble the complete setup.

This item is an ASA 140/2 roller chain from the DONGHUA brand. The designation indicates a chain with a 44.45 mm pitch, 25.4 mm roller diameter and 25.4 mm inner width. The /2 suffix corresponds to double-strand: two chains in parallel that share the same pins, which multiplies the pulling capacity without doubling the overall width. The ASA series is the American designation for roller chains, dimensionally equivalent to the ISO 28B series. It is manufactured by DONGHUA, a brand that MR sells.

Typical applications of a chain of this size are main drives of heavy machinery: mills, crushers, bucket elevators, drag conveyors, mining and cement equipment, and low-speed, high-torque drives. It is also used in the sugar industry and in aggregate processing plants. In all these cases, the chain works outdoors or in dusty environments and requires periodic lubrication and careful alignment of the sprockets.

To properly select this chain, take into account the number of teeth on the sprocket, the center distance and the power to be transmitted. The double strand allows reducing the pitch or the number of strands when space is limited, but it requires compatible double-row sprockets. Verify that the shaft and supports withstand the radial loads introduced by a chain of this size. Mounting must be done with the chain tensioned and the sprockets aligned; a misalignment of a few millimeters accelerates wear on rollers and plates.
