The POLEA 240 3B pulley is a V-belt drive pulley, manufactured by EMMAR Accesorios Industriales. It has a 240 mm diameter, 3 grooves and section B. It is used to transmit power between parallel shafts in industrial equipment, with the advantage of allowing several speed ratios depending on the combined diameters. Because it is in-house manufactured, the machining of the groove and the balancing are controlled, two key factors for the belt to run centered and last as long as it should.

This pulley has a 240 mm diameter, 3 grooves and section B. Section B defines the groove profile for V-belts of that size. The three grooves make it possible to mount three belts in parallel on the same disc, which distributes the load and provides redundancy: if one belt fails, the other two keep transmitting until it is replaced. The 240 mm diameter is combined with the pulley on the other shaft to set the transmission ratio. The groove machining and balancing are part of MR's own manufacturing.

Typical applications are equipment with electric motors and parallel shafts: fans, compressors, centrifugal pumps, conveyor belts, mixers and production machines. In food, chemical or materials plants, where there is a lot of dust or humidity, it is advisable to check the condition of the groove and the alignment more frequently. It is also used in factory equipment and in machines that are assembled or modified, where a pulley of known size and multiple grooves is needed so as not to fall short on power.

To select it, start from the motor power, the RPM of the drive shaft and the RPM you need on the driven shaft. With that data the ratio is defined and, with the 240 mm diameter, the diameter of the complementary pulley is calculated. Check that the belt section is B and that the number of grooves matches the number of belts you are going to mount. During assembly, align the pulleys with a straightedge or laser, tension the belts according to the manufacturer's manual and check that the keyway and the shaft fit without play.

If you need an equivalent pulley or a nearby size, send us the part number POLEA 240 3B or the diameter and number of grooves you are looking for. We can look at other section B pulleys with a different diameter or number of grooves, or a custom pulley if the equipment requires it. We can also advise you on the compatible belt and the bushing or mounting on the shaft. The more data you give us —diameter, grooves, section, shaft type—, the faster we will send you the alternative.

MR Accesorios Industriales manufactures this pulley and distributes it from Buenos Aires. If you need it for equipment that is down or for a new project, write to us on WhatsApp with the part number POLEA 240 3B and we will quote you.
