This item is an ASA 140 roller chain from Donghua, with a 44.45 mm pitch, 25.4 mm roller diameter and 25.4 mm inner width. The ASA 140 designation corresponds to the ANSI series with a 1 3/4 inch pitch, one of the most robust within standard roller chains. It is supplied in sections or rolls as needed. It is a power transmission chain, not a conveyor chain, and is used in sprocket drives.

Typical applications include primary drives in mills, crushers, bucket elevators, chain conveyors, cement machinery, mining and material handling equipment. It is also used in the sugar, paper and aggregate processing industries. Due to its pitch and strength, it is common in equipment where other smaller-pitch chains would not withstand the load or working conditions.

To correctly select an ASA 140 chain, take into account the power to be transmitted, the shaft speed, the number of sprocket teeth and the center distance. It is essential to verify sprocket alignment and proper lubrication to maximize service life. Installation must be done with the correct clearance and without forcing the pins. If you need advice, at MR Accesorios Industriales we can help you define the configuration.
