The ASA 160 chain is a roller chain with a 50.8 mm (2 inches) pitch, manufactured by DONGHUA, a brand offered by MR. It is used to transmit power between parallel shafts in high-load equipment, such as conveyors, mills, elevators and heavy machinery. Its steel construction allows it to absorb significant stresses and operate at moderate speeds with adequate lubrication. If you need to replace a worn chain or build a new transmission, this series is a robust option with standardized dimensions.

This item is a roller chain from the ASA series, designation ASA 160. Its main dimensions are: 50.8 mm pitch, 28.58 mm roller diameter and 31.75 mm inner width. The ASA series follows American standardization, so the pitch and rollers match those of other equivalent chains. DONGHUA manufactures it in carbon steel with heat treatment, which gives it wear resistance on pins and rollers. It is a large-pitch chain designed to transmit high force at low rpm.

Typical applications for an ASA 160 chain include drag conveyors, bucket elevators, mill drives, industrial mixers, mining equipment and large agricultural machinery. It is also used in overhead cranes and transmission systems where the shafts are separated by considerable distances. Because of its pitch and robustness, it is common in installations where mechanical strength is prioritized over speed. If the original equipment has a chain of this size, it is advisable to keep the same series to avoid modifying sprockets or chain wheels.

To install an ASA 160 chain, check that the sprockets have the correct pitch and are aligned. The tension must be adequate: too loose and it jumps, too tight and it accelerates wear on bushings and rollers. Lubricate with oil or grease compatible with the load and working speed. Check elongation periodically: when the chain stretches beyond the recommended limit, it must be replaced together with the sprockets if they are worn. In critical transmissions, use safety guards and monitor the operating temperature.

If you need an equivalent chain or a nearby size, send us the complete code or the pitch, roller and inner width dimensions. With that data we can look for alternatives within the same ASA series or from other brands we carry. We can also advise you if space is limited and a chain with a different pitch must be evaluated. The more accurate the information you send, the faster we can give you a useful answer.
