The 10-B3 chain is a European standard BS roller chain, with 5/8" pitch and triple strand, used to transmit power between separated shafts in industrial machines. Its construction with 10.16 mm diameter rollers and 9.65 mm inner width gives it wear resistance and good performance in continuous service. MR Accesorios Industriales offers it as part of its power transmission line, with more than 80 years of experience in the industry.

This item is a BS series roller chain, designated 10-B3. The number 10 corresponds to the 5/8" pitch, and the B3 suffix indicates triple strand, that is, three rows of rollers in parallel. According to the product data, the roller has a 10.16 mm diameter and the inner width is 9.65 mm. It is a steel chain, suitable for power transmission in applications requiring greater load capacity than a single or double chain.

It is used in chain drives for agricultural machinery, conveyors, elevators, mills, mixers, and process equipment. The triple strand allows handling higher loads or reducing the sprocket width for the same power. It also appears in low-speed, high-torque drives, where a single chain would be overstressed. It is common in manufacturing plants and in equipment operating in dusty environments or with intermittent lubrication.

To select correctly, check the chain pitch and the number of sprocket strands. The 10-B3 chain requires triple-strand sprockets compatible with the 5/8" pitch and 9.65 mm inner width. Check shaft alignment, proper tension, and the lubrication recommended by the equipment manufacturer. If the original drive uses a single or double chain, do not replace it with a triple without verifying that the sprockets and available space allow it.

If you need an adjacent size or an equivalent from another standard, send us the full part number and the pitch, inner width, and number of strands. You can also send a photo of the old chain or the sprocket. With that data, at MR Accesorios Industriales we look for the option that best suits your equipment, whether from the same BS series or another compatible one.
