The 90 2B pulley is a V-belt drive pulley of section B, with two grooves and 90 mm diameter. It is used to transmit power between parallel shafts in industrial equipment, where a defined transmission ratio and stable operation are needed. It is an in-house manufactured part, EMMAR brand, designed to integrate into power transmission systems with section B belts.

This pulley has 90 mm diameter, 2 grooves and section B. It is a cast iron or steel pulley, machined to accommodate section B V-belts. The two grooves allow transmitting more torque than a single-groove pulley, maintaining the same diameter. The designation POLEA 90 2B summarizes those three variables: diameter, number of grooves and belt section. It is manufactured at MR with dimensional control so that the shaft fit and groove alignment are correct.

It is used in fans, centrifugal pumps, compressors, conveyor belts and machine tools. Also in process equipment where revolutions need to be reduced or increased between a motor and the working shaft. Being section B, it accepts standard V-profile belts, which facilitates replacement in plants with already installed drives. It is common in workshops, food, textile and water treatment plants.

To mount it, verify that the shaft diameter matches the pulley bore and that the key fits without play. Align the pulleys with a straightedge or an alignment laser to avoid uneven belt wear. Belt tension is adjusted according to the equipment manual; excessive tension punishes the shaft bearings. If the pulley will work at high revolutions, dynamic balancing should be checked.

If you need a pulley with a different number of grooves, another diameter or a different section, you can request a neighboring size or an equivalent. To do so, send the part number POLEA 90 2B or the drawing of the part via WhatsApp to MR Accesorios Industriales. You can also indicate the outer diameter, bore diameter, width and belt section you use. With that data, the pulley that best fits is found.
