The 280 mm industrial pulley with 7 grooves for section B belts is a power transmission component that mounts on shafts to transfer motion via V-belts. It is used in machines and equipment where speed needs to be increased or reduced and power distributed across several grooves. Its robust construction and precise machining of the grooves ensure stable, long-lasting operation in demanding industrial applications.

This item is a pulley with a 280 mm diameter, 7 grooves and section B, per its designation POLEA 280 7B. The 280 mm measurement corresponds to the pitch or outside diameter depending on the design, a detail confirmed on the product page. The 7 grooves accommodate the same number of section B V-belts, making it possible to transmit higher power or provide redundancy in the drive. It is an in-house manufactured part, EMMAR brand, which guarantees control over materials and finish.

Typical applications include belt drives in mills, mixers, compressors, industrial fans, conveyor belts and machine tools. It is also used in pumping equipment and transmission systems where a specific speed ratio is required. With 7 grooves, it is common in installations that demand high torque capacity or where the load is distributed across several belts to reduce individual wear.

For mounting, verify that the shaft has the correct diameter and tolerance, and that the keyway matches the pulley's. Aligning the drive and driven pulleys is essential to avoid irregular belt wear and vibration. Belt tension must be as recommended by the belt manufacturer. When selecting, consider the power to be transmitted, the rotation speed and the pitch diameter to calculate the correct transmission ratio.

If you need a pulley with a different number of grooves, a different diameter or for another belt section, we can manufacture it or source it. To request an equivalent or a nearby size, send us the part number POLEA 280 7B or the data of the original pulley (diameter, grooves, section, bushing or taper type). With that information we will quote the option that best fits your machine.
