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

This pulley has a 90 mm diameter, 2 grooves and section B. It is a cast iron or steel pulley, machined to seat section B V-belts. The two grooves allow more torque to be transmitted than a single-groove pulley, while keeping 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 fit on the shaft and the 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 makes replacement easier in plants with drives already installed. 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 strains the shaft bearings. If the pulley is to run at high revolutions, it is advisable to check dynamic balancing.

If you need a pulley with another number of grooves, another diameter or a different section, an equivalent can be requested. To do so, send the part number POLEA 90 2B or the drawing of the part by WhatsApp to MR Accesorios Industriales. You can also indicate the outside diameter, the bore diameter, the width and the belt section you use. With that data we look for the pulley that best fits.
