The POLEA 90 4B pulley is an in-house manufactured power transmission pulley, EMMAR brand, with a 90 mm diameter, 4 grooves and section B. It is used to transmit motion between shafts by means of V-belts, in machines and equipment where speed needs to be increased or reduced. Being in-house production, it can be manufactured in different sizes and groove configurations according to what each application requires.

This item is a pulley with a 90 mm diameter, 4 grooves and section B. The designation POLEA 90 4B summarizes those three data points: size, number of grooves and belt section. Section B corresponds to V-belts with a B profile, and the 4 grooves allow building drives with several belts in parallel on the same pulley. Machining is done in our own factory, with dimensional control on the grooves and the central bore.

It is used in belt drives of machine tools, compressors, fans, pumps, conveyor belts and process equipment. Also in the field, in agricultural implements and in old machines where a worn or custom-made pulley needs to be replaced. Having 4 grooves, it is common in drives that need to transmit considerable power with section B belts, or where the load is to be distributed across several belts to reduce wear.

To select it, take into account the pitch diameter, the number of grooves, the belt section and the type of bore or bushing the shaft needs. Also check the center distance and the available belt length, because the transmission ratio depends on that. If the pulley is mounted on a shaft with a keyway, it is advisable to confirm the keyway size and the shaft diameter before manufacturing. Balancing and concentricity matter when the speed is high.

If you need a different diameter size, another number of grooves or a different section, it can be manufactured to order. To request an equivalent or a nearby size, send us the part number POLEA 90 4B or the data of the original pulley: diameter, grooves, section, shaft diameter and mounting type. With that we quote the closest part or manufacture it directly in the size needed.

MR Accesorios Industriales manufactures this pulley in its factory and sells it along with the rest of the power transmission line.
