The ASA 40 roller chain from EMMAR is a light-section drive chain built around a 12.7 mm (1/2 inch) pitch. It transfers motion between parallel shafts on a broad range of machinery. You will find it in our power transmission lineup, and it is identified by part number SC-ASA-40.
Key dimensions are pitch 12.7 mm, roller diameter 7.95 mm and inner width 7.95 mm. The ASA 40 callout follows the ANSI 40 standard, which sets a 1/2 inch pitch. Because the rollers turn on bushings, friction and wear are reduced and higher speeds become practical. Among power transmission chains, the ASA series is the most common general-purpose choice.
Typical drives include machine tools, light conveyors, packaging equipment, door operators, agricultural machinery and material handling systems. Food processing and production lines also use this chain where a dependable, low-maintenance drive is needed. Gear reducers and gearmotors that rely on chains for motion transfer are another frequent application.
When selecting an ASA 40 chain, review the power to be transmitted, the rotation speed, the center distance and the operating environment. Confirm that the sprockets match both the pitch and the roller diameter. Set tension correctly at installation: an over-tight chain speeds up bearing wear, while a loose one may jump. Follow a periodic lubrication schedule based on the service.
If your machine calls for ASA 35, ASA 41 or ASA 50, or a chain with special features, we can help you locate an equivalent. Send the exact part number, the brand and the dimensions from the nameplate or manual. We can also advise on lubrication and maintenance for your specific drive.
