For drives that demand greater tensile capacity than a single-strand chain, the 08-B2 double-strand roller chain offers a proven solution. Built to European BS standards with a 1/2-inch pitch, this wear component is designed for parallel shaft power transmission and is replaced when elongation or roller wear exceeds acceptable limits. MR supplies it under part number 08-B2 for replacement and new drive assemblies.

The 08-B2 designation breaks down into three key details: the 08 series, the B standard (European BS), and the 2 indicating double-strand construction. Two rows of rollers ride on shared pins, effectively doubling tensile capacity compared with a single-strand 08-B1 of the same pitch. Roller diameter is 8.51 mm and inner width is 7.75 mm. The chain is available assembled or in sections with a connecting link, and its pitch and roller dimensions match sprockets of the same standard.

Typical applications include agricultural machinery, conveyors, mixers, blowers, mills, and process equipment. It is also found in bottling lines, conveyor belts, and machine tools, particularly where a constant transmission ratio and low maintenance are desired. The double-strand design is selected when a single-strand chain of the same pitch is near its load limit, or when two rows fit the axial space and a larger-pitch chain would be too wide.

Proper selection starts with verifying sprocket pitch, tooth counts, center distance, and transmitted power. Lubrication is critical: higher speeds and loads call for more viscous oil and more frequent application. Check sprocket alignment and slack-side tension; an overly tight chain accelerates bushing and roller wear. In dusty or humid environments, consider a surface-treated chain or an automatic lubrication system.

To request an equivalent, provide the full code, pitch, number of strands, and number of links or total length. With that data, MR can quote the 08-B2, a single-strand 08-B1, or a larger-pitch chain if needed. Connecting links and matching sprockets are also available. Incomplete codes are confirmed against the manufacturer's data sheet before quoting.

For a quote, send the part number by WhatsApp to MR along with the required number of links or length. If you are unsure about cross-referencing to another standard, include a photo of the existing chain or sprocket. This helps ensure the correct option is offered without unnecessary changes.
