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

This item is an ASA 140/2 roller chain from the DONGHUA brand. The designation indicates a chain with a 44.45 mm pitch, with 25.4 mm diameter rollers 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 traction capacity without doubling the total width. The ASA series is the American designation for roller chains, equivalent in dimensions to the ISO 28B series. It is manufactured by DONGHUA, an official brand that MR carries.

Typical applications for 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 sprocket alignment.

To properly select this chain, take into account the number of sprocket teeth, 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. Installation must be done with the chain tensioned and the sprockets aligned; a misalignment of a few millimeters accelerates roller and plate wear.

If you need a nearby size or an equivalent from another brand, send us the complete code and the main measurements: pitch, roller diameter and inner width.
