Description
EMMAR 24-B1 is a roller chain reference, within Power transmission. Request a quote for 24-B1 via WhatsApp or email with the quantity you need; we respond promptly with lead time and equivalents.
The 24-B1 chain is a European standard BS roller chain, with 1 inch pitch, used to transmit motion between separated shafts in industrial machines. Its single-strand design and 25.4 mm diameter rollers make it suitable for moderate loads and medium speeds. At MR Accesorios Industriales we sell it as part of our power transmission line, along with sprockets and accessories for system assembly.
This item is a single-strand roller chain, identified as 24-B1 under European standard BS. The code 24 indicates 1 inch (25.4 mm) pitch, and the suffix B1 indicates a single strand. The datasheet confirms a roller diameter of 25.4 mm and an inner width of 25.4 mm. The BS series groups chains of equivalent metric pitch, widely used in equipment of European origin. To confirm compatibility with your machine, have the pitch and inner width at hand.
24-B1 chains appear in low and medium speed drives: belt or roller conveyors, bucket elevators, packaging machines, mixers, and process equipment. They are also found in the food, ceramic, and chemical industries, where European standard chains are preferred due to the availability of sprockets and spare parts. If your original equipment uses a BS chain, replacing it with one of the same designation simplifies maintenance and avoids modifying the existing sprockets.
To select correctly, check the pitch, inner width, and roller diameter, which must match those of the sprocket. Also check the number of strands: a B1 is single; if you need more capacity, consider a B2 or B3. During installation, align the shafts and check tension: a chain that is too tight accelerates wear on bushings and rollers, and a loose one skips teeth. Lubricate according to the environment and speed, and check elongation periodically to schedule replacement.
If you cannot find the exact size or need an equivalent chain, write to us with code 24-B1 and the measurements of your sample. We can offer a chain from another standard or a nearby size, as long as pitch, width, and roller match. We also supply sprockets and connecting links to complete the system. Send your inquiry via WhatsApp to MR Accesorios Industriales and we will reply with the options we handle.
At MR Accesorios Industriales we have worked with power transmission for more than 80 years. In addition to chains, we sell bearings, housings, seals, and lubricants for industrial maintenance. If your equipment requires a 24-B1 chain, send us the code and measurements; we will quote you via WhatsApp and advise you so that the replacement is correct.

Frequently Asked Questions
- What does 24-B1 mean in a chain?
- The 24 indicates a 1 inch (25.4 mm) pitch according to European standard BS. The B indicates the series, and the 1 that it is single strand. The datasheet for this item confirms a 25.4 mm roller and 25.4 mm inner width.
- How do I request a chain equivalent to 24-B1?
- Send via WhatsApp the code 24-B1 and the pitch, inner width, and roller measurements of your sample. With that data we look for a chain from another standard or a nearby size that is compatible with your sprockets.
- What lubrication does a BS roller chain need?
- It depends on speed and environment. Generally, oil or grease of adequate viscosity is used, applied to the rollers and bushings. Avoid lubricants that attract dust if you work in dirty environments. Ask us about the right lubricant for your application.
