The 90 3A pulley is a V-belt drive pulley, with a 90 mm diameter and three section A grooves. It is used to drive parallel shafts in equipment that needs a fixed transmission ratio and good belt grip. It is in-house manufacturing, EMMAR Accesorios Industriales brand, which allows sizes and grooves to be replaced according to the equipment's needs.

This item is a pulley with a 90 mm diameter, 3 grooves and section A. The designation POLEA 90 3A summarizes those three variables: size, number of grooves and belt profile. Section A corresponds to classic V-belts with a narrow profile, suitable for transmitting power in reduced spaces. Since it is in-house manufacturing, EMMAR brand, you can ask about variants of diameter or number of grooves within the same section.

Typical applications are machines with belt drives: compressors, fans, centrifugal pumps, conveyor belts and factory equipment. It is also used in reducers and multipliers where a stable output speed must be maintained. Having three grooves allows the load to be distributed among several belts, which reduces the stress on each one and improves drive continuity.

To mount a 90 3A pulley, first verify the shaft diameter and the type of fastening (keyway, set screw or taper bushing). Check that the pulley is aligned with the drive pulley: angular or parallel misalignment accelerates wear on the belt and on the equipment's bearings. Belt tension is adjusted according to the machine manufacturer's manual; excessive tension stresses the supports and low tension makes the belt slip.

If you need an equivalent pulley or a nearby size, the most practical thing is to send the part number POLEA 90 3A by WhatsApp to MR Accesorios Industriales. You can also indicate the outside diameter, the number of grooves, the belt section and the shaft diameter. With that data we look for the pulley that best suits you, whether from the same section A or another section if the equipment requires it.
