When you need to transfer torque across distant shafts in tough industrial settings, the Donghua ASA 140 roller chain is a solid choice. It features a 44.45 mm (1 3/4") pitch, 25.4 mm roller diameter, and 25.4 mm inner width. MR Industrial Accessories supplies this chain for both maintenance replacements and new installations.

The ASA 140 chain is part of the ANSI series, with a 1 3/4-inch pitch that places it among the more rugged standard roller chains. It is designed for power transmission between sprockets, not for conveyor service. You can order it in sections or full rolls to match your job requirements.

You will often find this chain in primary drives for mills, crushers, bucket elevators, and material handling systems. It also sees use in cement plants, mining equipment, and aggregate processing. Its larger pitch and robust build make it suitable where smaller chains would fail under load or harsh conditions.

Proper selection involves checking the power to be transmitted, shaft speed, sprocket tooth count, and center distance. Correct sprocket alignment and adequate lubrication are critical for long service life. During installation, maintain the specified clearance and avoid forcing the pins. Our team can assist you in determining the right setup.

If you need a different size or an equivalent, just provide the ASA 140 code or your chain's measurements (pitch, inner width, roller diameter) via WhatsApp. We can suggest compatible options. We also manufacture ANSI chains and pulleys.
