The POLEA 130 3A pulley is a V-belt drive pulley, in-house manufactured, EMMAR brand, with a 130 mm diameter and 3 grooves for section A belts. It is used to drive parallel shafts in industrial equipment, where torque must be transmitted with a defined transmission ratio. Because it has three grooves, it allows distributing the load among three belts and adding power without changing the diameter. It is a common replacement part in machines already in the plant.

This item is a pulley with a 130 mm diameter, 3 grooves and section A. The designation POLEA 130 3A summarizes those three variables: size, number of grooves and belt profile. Section A corresponds to a classic industrial drive belt profile, and the three grooves allow installing three belts in parallel on the same body. The 130 mm diameter defines the transmission ratio when combined with another pulley in the same system.

It is used in belt drives of machine tools, compressors, fans, centrifugal pumps, conveyor belts and process equipment. It also appears in reducers and multipliers where a fixed ratio between two shafts is needed. Because it has three grooves, it is common in drives that require more power than a single-groove drive, while keeping the same pulley diameter.

To mount it, verify that the shaft diameter matches the pulley bore and that the keyway is in good condition. Align the pulleys with a straightedge or a laser alignment tool to avoid uneven belt wear. Belt tension is adjusted according to the equipment manual or with a tension gauge. If you are replacing an existing pulley, compare the number of grooves, the section and the diameter before ordering.

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 in-house manufacturing line, EMMAR brand. To do so, send the part number POLEA 130 3A or the designation of the original pulley by WhatsApp, along with a photo of the part and the shaft measurement. With that data, the equivalence is confirmed.
