It is used to transmit motion between parallel shafts in industrial equipment, with the advantage of being a standard and replaceable component. At MR Accesorios Industriales we sell it for the assembly of new drives or replacement, and we advise you so you can choose the right chain for your application.

This item is a single-strand roller chain of the 20-B1 series, manufactured to European BS standard. Its main attributes are a roller diameter of 19.05 mm and an inner width of 19.56 mm. The 1 1/4-inch pitch places it in the medium-to-high power transmission chain range, and its 20-B1 designation indicates it is a single-strand chain. It is used with compatible sprockets of the same standard and pitch, and it is a common option when a robust chain that is easy to replace is needed.

Typical applications include drives in agricultural machines, conveyors, lifting equipment, mixers, mills and production lines in general. It is also used to drive pumps, compressors and industrial fans. Because of its roller construction, it tolerates moderate speeds and variable loads, provided the installation and lubrication are suitable. It is commonly found in equipment where a European standard chain with good wear resistance is required.

To correctly select this chain, take into account the pitch, the number of sprocket teeth, the center distance and the power to be transmitted. Verify that the sprockets are compatible with the BS standard and the 1 1/4-inch pitch. Installation must be done with the chain correctly tensioned and aligned; excessive tension accelerates wear on rollers and bushings, while low tension can cause jumping. Periodic lubrication is key to extending the service life of the assembly.

If you need a nearby size or an equivalent, you can ask us with the 20-B1 code or with the measurements of your current chain: pitch, roller diameter, inner width and number of strands. We can also help you identify the chain from a sample or from the sprocket measurements. At MR Accesorios Industriales we have experience in power transmission and we guide you so you can find the right chain for your equipment.
