The POLEA 500 2B pulley is a V-belt drive pulley with section B, two grooves and a 500 mm diameter. It is used to transmit power between parallel shafts in industrial equipment, where a stable transmission ratio and good belt grip are needed. It is an in-house manufactured part, EMMAR brand, designed to replace worn pulleys or to build a new drive. It is machined with the necessary tolerances so that the belts seat properly in the grooves and the assembly runs without vibration.

This item is a pulley with a 500 mm diameter, 2 grooves and section B. The designation POLEA 500 2B summarizes those three characteristics: the outside diameter, the number of grooves and the belt profile it accepts. Section B corresponds to classic B-profile V-belts, widely used in industrial drives. Because it is in-house manufactured, EMMAR brand, the groove machining and balancing are controlled so that the pulley rotates without jumps and the belts do not come off.

It is used in machine and equipment drives where speed needs to be reduced or increased between a motor and a driven shaft. It appears in fans, compressors, pumps, conveyor belts, mixers and mills, among other applications. It is also common in factory equipment and in agricultural or road machinery that runs with section B belts. Having two grooves allows mounting two belts in parallel to distribute the load and improve drive reliability.

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 laser to avoid uneven wear on belts and bearings. Belt tension is adjusted according to the equipment manual: too loose slips, too tight stresses the supports. If you are replacing an existing pulley, compare the pitch diameter, number of grooves and section before ordering. The pulley does not include a bushing or key unless indicated.

If you need a pulley with a different number of grooves, another diameter or a different section, it can be manufactured or a nearby size can be found within the power transmission line. To do this, send us the part number POLEA 500 2B or the data of the original pulley: diameter, grooves, section and shaft diameter. With that data we will confirm the equivalence or the closest variant. We can also advise you on the type of bushing or mounting if you tell us what the equipment is like.

MR Accesorios Industriales manufactures this pulley and sells the entire power transmission line: belts, bushings, housings and bearings. If you have questions about the POLEA 500 2B pulley or want to request a quote, write to us on WhatsApp with the part number and we will reply with the technical information you need.
