The pulley 50 2A is a V-belt drive pulley, 50 mm diameter and 2 grooves for section A belt. It is used to build or replace transmissions where the number of belts needs to be doubled without increasing the pulley diameter. It is in-house manufactured, EMMAR Accesorios Industriales brand, which allows the machining and finish to be adjusted to what each equipment requires.

This item is a pulley with 50 mm diameter, 2 grooves and section A. The designation POLEA 50 2A summarizes those three variables: outside diameter, number of grooves and the belt profile it houses. The grooves are machined for section A V-belts, so that the belt rests on the flanks and not on the bottom. It is an in-house manufactured part, EMMAR brand, designed for compact transmissions that need more than one belt on the same shaft.

It is found in low and medium power equipment: fans, exhausters, small compressors, centrifugal pumps, light conveyor belts, woodworking machines and mixers. It is also used as a replacement pulley in old machines where the original size is no longer available. Having two grooves allows transmitting more torque than a single pulley of the same diameter, or continuing to operate with only one belt if the other breaks and you need to get by.

To mount it, verify that the shaft diameter and keyway type match the pulley bore, and that the drive and driven pulleys are aligned in the same plane. Belt tension is adjusted so that they yield slightly when pressed with the thumb. If you are replacing an existing pulley, take the outside diameter, number of grooves, section and bore diameter before ordering. With that data, it is determined whether the pulley 50 2A is the correct one.

If you need a nearby size, a different diameter or more grooves, you can request an equivalent or a custom pulley. For that, it is advisable to send the original code, a photo of the part and the shaft measurements. At MR Accesorios Industriales we manufacture pulleys and also work with bearing, housing, chain and seal lines, so if the replacement comes with other components, everything can be quoted together.

If you have doubts about the section or the number of grooves, write anyway: with the designation and a photo of the equipment, it is quickly confirmed whether it is the pulley you are looking for or if another variant is needed.
