The industrial pulley, 320 mm with 2 grooves for section A, is a power transmission component that mounts on a machine shaft to transmit motion through V-belts. It is used in equipment that requires a fixed transmission ratio and good drive capacity, such as fans, compressors, pumps and conveyors. It is an in-house manufactured part, EMMAR brand, designed for replacement and for new projects.

This pulley has a 320 mm diameter, 2 grooves and section A. The designation POLEA 320 2A summarizes those three variables: the outer diameter, the number of grooves and the belt profile it accepts. Section A corresponds to classic V-belts with a narrow profile, suitable for transmitting power at moderate center distances. Because it is in-house manufactured, EMMAR brand, you can ask about variants within the same series.

It is used in machines that need to transmit motion continuously: industrial fans, screw compressors, centrifugal pumps, conveyor belts and mixers. It also appears in process equipment where a stable transmission ratio and low maintenance are required. Having two grooves allows doubling the transmission capacity compared with a single-groove pulley of the same diameter, or running with a single belt if the service allows it.

To select correctly, you must check the shaft diameter, the type of keyway and the fixing system (set screw, cone or bushing). You must also check the alignment between pulleys and the belt tension: an off-center pulley accelerates wear on the profile and on the equipment's bearings. The number of grooves must match the number of belts required by the drive; it is not advisable to mix new and used belts in the same set.

If you need a pulley with a different number of grooves, another diameter or a different section, you can request an equivalent or a nearby size within the same line. To do so, it is best to send the full code, the belt section and the required number of grooves. It also helps to attach a photo of the original pulley or indicate the shaft and keyway dimensions. With that data, the closest option available from the factory is found.
