The 08-B2 chain is a double-strand roller chain to European BS standard, with 1/2 inch pitch. It is used to transmit motion between parallel shafts when more load capacity is needed than a single-strand chain of the same pitch. It is a wear component: it is replaced when elongation exceeds the permissible limit or when the rollers and plates show pitting. MR Accesorios Industriales supplies it under part number 08-B2 for replacement and transmission assembly.

The code 08-B2 identifies a double-strand roller chain, 1/2 inch pitch, to European BS standard. Its published attributes are roller diameter 8.51 mm and inner width 7.75 mm. The B2 designation indicates two rows of rollers on the same pins, which doubles the tensile capacity compared with a single-strand chain of the same pitch. It comes assembled or in sections with a connecting link. The pitch and roller dimensions are compatible with sprockets of the same standard.

It is used in chain drives on agricultural machinery, conveyors, mixers, blowers, mills and process equipment. Also in low- and medium-speed drives where a constant transmission ratio and low maintenance are required. It is commonly found in bottling lines, conveyor belts and machine tools. Because it is double-strand, it is chosen when a single-strand chain of the same pitch is at its load limit or when the axial space allows two rows and the total width is to be reduced compared with a chain of larger pitch.

To select correctly, check the sprocket pitch, the number of teeth on both wheels, the center distance and the power to be transmitted. Lubrication is decisive: the higher the speed and load, the more viscous the oil and the more frequent the replacement. Check sprocket alignment and slack-side tension; a chain that is too tight speeds up wear on bushings and rollers. If the drive works in a dusty or humid environment, consider a chain with surface treatment or an automatic lubrication system.

If you need a nearby size or an equivalent, send us the full code, the pitch, the number of strands and the number of links or the total length. With that data we can offer you the 08-B2 chain, a single-strand 08-B1 or a larger-pitch chain if the application requires it. We can also quote the connecting link and the matching sprockets. If the code is incomplete, we confirm it against the manufacturer's data sheet before quoting.

To request a quote for your 08-B2 chain, send the code by WhatsApp to MR Accesorios Industriales along with the number of links or the length you need. If you are unsure about equivalence with another standard, attach a photo of the old chain or the sprocket. That way we reply with the right option and avoid unnecessary changes.
