The 12-B3 chain is a 3/4" pitch roller chain according to European standard BS, with 12.07 mm diameter rollers and 11.68 mm inner width. It is used to transmit power between parallel shafts in industrial equipment, and is a common option when worn chains need to be replaced or new drives assembled. At MR Accesorios Industriales you can get it with technical advice so you choose the right size.

This item is a single-strand roller chain from the BS series, identified as 12-B3. Its rollers have a diameter of 12.07 mm and an inner width of 11.68 mm, dimensions that define its ability to mesh with compatible sprockets. European standard BS groups 3/4" pitch chains with standardized dimensions, which makes interchangeability easier between different manufacturers that comply with the same standard. It is a power transmission chain, not a conveyor or drag chain.

It is used in chain drives for industrial machinery: conveyors, mixers, mills, elevators, machine tools and process equipment. It also appears in low- and medium-speed drives where a constant transmission ratio and wear resistance are required. It is commonly found in production lines that run with 3/4" pitch sprockets and in equipment where the space between shafts is fixed. If the original equipment has a BS chain, this series is usually the natural replacement.

To install it, verify that the sprockets have the correct pitch and number of teeth, and that the alignment between shafts is correct. Lubrication and tension directly affect service life: an overly tight chain accelerates wear on rollers and bushings, and one that is too loose jumps or hits. Also check the condition of the sprockets, because a worn sprocket wears out the new chain within a few hours of operation. If in doubt, consult us and we will help you select.

If you need an adjacent size or an equivalent, send us the complete code, the number of links, the pitch and a photo of the old chain if you have it. With that data we can identify the corresponding BS series and offer you compatible alternatives. We can also quote the chain with or without a joint, depending on how you are going to install it. You do not need to have the technical datasheet on hand: with the 12-B3 code we can already guide you.

To request a quote for the 12-B3 chain, send the code via WhatsApp to MR Accesorios Industriales. We will reply with the size or equivalent options that best suit your equipment. If you also need sprockets, lubricants or assembly tools, we can include everything in the same inquiry. More than 80 years supporting Argentine industry with power transmission components.
