The 130 1B pulley is a power transmission pulley of in-house manufacturing, EMMAR brand, designed to build and replace belt drives in section B. With a 130 mm diameter and a single groove, it is a part of common use in machines that need a simple transmission ratio and direct mounting on the shaft. It is machined at MR Accesorios Industriales, so you can ask about nearby sizes or a pulley with more grooves within the same section.

This item is a pulley with a 130 mm diameter, 1 groove and section B. The designation POLEA 130 1B summarizes those three data points: the outside diameter, the number of grooves and the belt section it houses. It is a single-groove pulley, meaning it works with a single section B V-belt, without the multi-groove variants used when the load needs to be distributed among several belts. The part is of in-house manufacturing, EMMAR brand.

Typical applications are belt drives in section B: fans, small compressors, pumps, light conveyor belts, factory machines and process equipment where a simple reduction or multiplication is sought. Because it has a single groove, it is chosen when the power to be transmitted falls within the range of one B belt and there is no need to duplicate grooves. It is also used as a replacement pulley when the original wore at the groove or was hit and no longer fits the belt properly.

To select it, take into account the pitch diameter required by the transmission ratio, the belt section the machine already uses and the shaft diameter where it is mounted. Check the keyway and the fastening system before ordering it, because a pulley of the same diameter may come with a different bore. If the drive works under heavy load or with frequent starts, it is worth evaluating moving to a pulley with more grooves in the same section instead of forcing a single-groove one.

If you need an equivalent or a nearby size, send us the part number POLEA 130 1B along with the machine data: shaft diameter, belt section, number of grooves and the diameter you are looking for. Since the pulley is of in-house manufacturing, we can see whether there is a nearby size in the same section B or whether it is better to machine the part with the dimensions you need. The more complete the information, the faster we can reply.
