The 08-B1 chain is a power transmission component with 12.7 mm (half inch) pitch under European standard BS. It is used to drive parallel shafts in machines where a constant and reliable transmission ratio is needed. Its 8.51 mm diameter rollers and 7.75 mm inner width make it compatible with sprockets of the same standard. At MR Accesorios Industriales you can request a quote by WhatsApp and we advise you so you choose the right chain for your equipment.
This item is a single-strand roller chain from the 08-B1 series, manufactured under European standard BS. The pitch is 12.7 mm (half inch) and its main attributes are the 8.51 mm roller diameter and 7.75 mm inner width. The designation 08-B1 indicates that it is a single-strand chain, with rollers that rotate on bushings to reduce wear. It is supplied in standard-length sections and can also be assembled to order with connecting links and half links.
Typical applications of the 08-B1 chain include low- and medium-power drives in machine tools, light conveyors, packaging equipment, mixers, pumps, and fans. It is also found in the food industry and in assembly lines where movements must be synchronized. Because of its BS standard, it is common in equipment of European origin or in replacements for worn chains that already work with 12.7 mm pitch sprockets.
To install an 08-B1 chain, verify that the sprockets have the same pitch and are aligned. Correct tension is achieved with a slight sag on the slack side; if it is too tight, the bearings suffer; if it is too loose, it jumps. Lubricate with oil or grease according to speed and environment. Check wear by measuring elongation: when it exceeds 1.5%, it is best to replace the chain and sprockets together to avoid premature wear.
If you need an equivalent chain or a neighboring size, send us the 08-B1 code or the measurements of your current chain: pitch, inner width, and roller diameter. We can also offer you the custom version with the number of links you require. At MR Accesorios Industriales we help you identify the right chain for your machine and provide a quote by WhatsApp.
To order your 08-B1 chain, write to us on WhatsApp with the code and the number of meters or links. We will reply with the quote and the applicable alternatives. MR Accesorios Industriales has more than 80 years supporting industry with power transmission, bearings, and accessories.
