The POLEA 170 4A pulley is a V-belt drive pulley, section A, with a 170 mm diameter and 4 grooves. It is used to drive shafts from a motor, distributing power across several belts to transmit more torque without slipping. It is in-house manufactured, EMMAR brand, designed for equipment that runs many hours a day and needs a balanced pulley, with machined grooves and a good fit on the shaft.

This item is a pulley with a 170 mm diameter, 4 grooves and section A. Section A corresponds to classic narrow-profile V-belts, and the 4 grooves allow four belts to be mounted in parallel on the same pulley. The 170 mm diameter defines the drive ratio when combined with another pulley in the same system. The part is manufactured at MR with dimensional control on the outer diameter, groove width and center bore, so that the belts seat evenly.

It is used in drives for machine tools, compressors, fans, centrifugal pumps, conveyor belts and factory equipment. It also appears in mixers, exhausters and process lines where speed needs to be increased or reduced with section A belts. With 4 grooves, it is common in drives that require more torque capacity than a one- or two-groove pulley, while keeping the same diameter.

To select it, check that the belt is section A and that the number of grooves matches the number of belts you are going to mount. Check the bore diameter and the type of shaft keyway before installing it. Alignment between the driving and driven pulleys is key to belt life: angular or parallel misalignment accelerates flank wear. Tension the belts according to the equipment manual and check balancing if the pulley rotates at high speed.

If you need a different diameter size, a different number of grooves or a different section, send us the drive data: current pulley diameter, belt section, number of grooves and shaft diameter. With that we can source or manufacture an equivalent pulley. If you do not have the part number at hand, a photo of the mounted pulley and the measurement taken with a caliper on the outer diameter help identify the part.
