For drives that demand high pulling capacity and fatigue resistance, the DONGHUA ASA 200/2 roller chain is a double-strand solution built to handle demanding industrial environments. MR Industrial Accessories supplies this chain and assists you in selecting the right configuration for your machinery.
This DONGHUA ASA 200/2 chain features a 63.5 mm pitch, a roller diameter of 39.68 mm, and an inner width of 38.1 mm. The ASA 200/2 designation identifies a double-strand chain, which increases load capacity compared to a single-strand version. It is produced from alloy steels and subjected to heat treatments that enhance wear and fatigue resistance.
Typical applications include mills, crushers, chain conveyors, bucket elevators, rotary kiln drives, and drilling equipment. It is also found in cement, mining, and steel operations, as well as aggregate processing plants. Its construction allows it to perform in dusty conditions, moderately high temperatures, and shock loads.
When selecting this chain, consider the power to be transmitted, rotation speed, center distance, and lubrication method. Confirm that sprockets match the 63.5 mm pitch and that shaft alignment is precise. Proper tension during installation is critical: excessive tension accelerates wear on rollers and bushings, while insufficient tension can cause the chain to jump off the sprocket.
If you need an equivalent chain, we can help. We offer DONGHUA ASA/ANSI chains in single, double, or triple strand options, along with connecting links and compatible sprockets. To get a recommendation, provide the exact part number, number of strands, and critical dimensions of your equipment.
