The EMMAR ASA 100/2 chain is a double-strand roller chain manufactured according to the ASA/ANSI standard. It is used to transmit power between parallel shafts in industrial equipment, with the advantage of doubling the load capacity compared to a single-strand chain of the same pitch. It is a common wear part in maintenance, so it should be selected carefully and the condition of the sprockets checked before replacing it.
This item is an ASA 100/2 roller chain, identified with the code ASA 100/2. Its main attributes are: pitch of 31.75 mm, roller diameter of 19.05 mm and inner width of 19.05 mm. The 100/2 designation indicates that it is a double-strand chain, meaning it has two rows of linked rollers, suitable for transmitting more torque than an equivalent single-strand chain. SC is an official brand that MR carries, so the chain is available through MR Accesorios Industriales.
Typical applications of an ASA 100/2 chain include power transmission in heavy machinery, conveyors, elevators, mining equipment, cement plants and process plants. It is also used in gearboxes and drive systems where high tensile strength and good shock behavior are required. Because of its double strand, it is common in equipment handling high loads or requiring a greater safety factor on the same sprocket diameter.
To correctly install an ASA 100/2 chain, verify that the sprockets are compatible with the 31.75 mm pitch and do not show excessive tooth wear. Shaft alignment and proper tension are key to avoiding skipping and premature wear. If the drive operates in a dirty environment or with little lubrication, consider a chain with surface treatment or an automatic lubrication system. The final selection depends on power, speed and service conditions.
If you need a nearby size or an equivalent, you can inquire about other chains in the ASA series with a different pitch or number of strands. For that, the most practical approach is to send the code ASA 100/2 or the original chain's code by WhatsApp to MR Accesorios Industriales. You can also provide the sprocket dimensions and number of teeth so we can guide you toward the most suitable option.
MR Accesorios Industriales has more than 80 years in the industry and carries bearings, power transmission, seals and mounting tools. If this ASA 100/2 chain is for a running machine, send us the code by WhatsApp and we will provide the quote. We can also advise you on sprockets, tensioners and lubricants for the same system.

Frequently Asked Questions
- What does it mean that the chain is ASA 100/2?
- The ASA 100/2 designation corresponds to a double-strand roller chain according to the ASA/ANSI standard. The number 100 indicates the 31.75 mm pitch and the /2 indicates that it has two rows of rollers, which allows it to transmit more load than a single-strand chain of the same pitch.
- How do I know if I need a double or single chain?
- It depends on the power to be transmitted and the available space. The double strand doubles the load capacity on the same pitch, but requires two-strand sprockets. If the original drive is single-strand, you will most likely need to keep that type to avoid changing the sprockets.
- Can I request a chain with a different pitch or number of strands?
- Yes. At MR Accesorios Industriales we carry various chains in the ASA series. Send the original chain's code or the pitch dimensions and number of strands by WhatsApp, and we will quote the option that best suits your equipment.
