The 360 3A pulley is a power transmission pulley manufactured by EMMAR, with a 360 mm diameter, 3 grooves and section A. It is used to drive shafts via V-belts in industrial equipment where torque must be transmitted with a defined transmission ratio. Because it is in-house manufactured, MR controls the groove machining and balancing, which helps maintain concentricity and alignment during assembly.

This pulley has a 360 mm diameter, 3 grooves and section A. Section A corresponds to classic narrow-profile V-belts, and the 3 grooves allow the load to be distributed among three belts, which provides greater transmission capacity than a single-groove pulley. The 360 mm diameter defines the transmission ratio when combined with the pulley on the driven shaft. MR manufactures it with dimensional control of the groove and concentricity verification so that the belts seat evenly.

It is used in belt drives for machines and equipment: fans, compressors, centrifugal pumps, mills, mixers, conveyor belts and test benches. Also in applications where the motor shaft speed must be reduced or increased with a large-diameter, multi-groove pulley. It is common in installations that already work with section A belts and need to replace an existing pulley while keeping the same number of grooves and diameter.

To select it, take into account the pitch diameter, the number of grooves and the belt section. Check that the keyway and the bore diameter match the shaft, and that the balancing is suitable for the rotation speed. During assembly, align the pulleys with a straightedge or laser to prevent uneven belt wear and vibration. Belt tension is adjusted according to the equipment manual; low tension causes slipping and excessive tension stresses the shaft bearings.

If you need a pulley with a different number of grooves, another diameter or a different section, you can request an equivalent. To do so, send the part number MR-POLEA-A3-360 or the designation POLEA 360 3A by WhatsApp, along with the shaft diameter, the keyway and the belt section you use. With that data, MR Accesorios Industriales will send you a quote.

MR Accesorios Industriales manufactures this pulley in its factory. If you have doubts about the equivalence with a pulley that is no longer available, send a photo or a drawing of the shaft and we will help you define the size. Service is via WhatsApp, with technical response.
