The ASA 40/2 chain is a double-strand roller chain, with a 12.7 mm pitch, 7.95 mm roller diameter and 7.95 mm inner width. It is used in power transmissions where greater load capacity is needed than a single-strand chain of the same pitch, while maintaining the same sprocket. It is an ASA series chain, manufactured under ANSI standard, and MR Accesorios Industriales markets it as part of its power transmission line.

This item is an ASA 40/2 roller chain, that is, double-strand, with the following dimensions: 12.7 mm pitch, 7.95 mm roller diameter and 7.95 mm inner width. The ASA 40/2 designation indicates that it is a 40 pitch (half inch) chain with two roller strands, which doubles the traction capacity compared with the single-strand version. It is an ASA series chain, which complies with the ANSI standard for roller chains.

Typical applications of an ASA 40/2 chain include power drives in agricultural machinery, conveying equipment, machine tools and lifting systems where greater strength than a single-strand chain is required. It is also used in gearboxes and transmission cases that need two strands to distribute the load. It is common in equipment where space is limited and the chain pitch cannot be increased.

To install an ASA 40/2 chain, check that the sprockets are compatible with the 12.7 mm pitch and are wide enough to accommodate the two strands. Sprocket alignment is critical: misalignment accelerates wear on the rollers and teeth. Lubrication must be adequate and tension correct to prevent skipping. If you replace a single-strand chain with a double-strand one, check that space and supports allow it.
