The ASA 200/2 chain is a double-strand roller chain with a 63.5 mm pitch, manufactured by DONGHUA. It is used in power transmissions that require high pulling capacity and fatigue resistance, such as heavy machinery, mining equipment, cement plants and lifting systems. MR Accesorios Industriales carries this brand and advises you on choosing the right chain for your application.

This item is a DONGHUA ASA 200/2 roller chain. Its pitch is 63.5 mm, the roller diameter is 39.68 mm and the inner width is 38.1 mm. The ASA 200/2 designation indicates that it is a double-strand chain, which doubles the load capacity compared with the single-strand version. It is manufactured with alloy steels and heat treatments that give it wear and fatigue resistance.

ASA 200/2 chains are used in high-power transmissions: mills, crushers, chain conveyors, bucket elevators, rotary kiln drives and drilling equipment. They also appear in the cement, mining and steel industries and in aggregate processing plants. Their robust construction makes them suitable for dusty environments, moderately high temperatures and shock loads.

To correctly select this chain, take into account the power to be transmitted, the rotation speed, the center distance and the type of lubrication. It is essential to verify that the sprockets are compatible with the 63.5 mm pitch and that the shaft alignment is accurate. Installation must be carried out with the proper tension: a chain that is too tight accelerates wear on rollers and bushings; one that is too loose can jump off the sprocket.
