The 210 3A pulley is a V-belt drive pulley, manufactured by EMMAR Accesorios Industriales. It has a 210 mm diameter and 3 grooves for section A belts. It is used to transmit motion between parallel shafts in industrial machines and equipment, where a defined transmission ratio is needed and the possibility of adjusting it by changing groove or diameter. Its in-house construction allows the bore and keyway machining to be adapted to each application.

This item is a pulley with a 210 mm diameter, 3 grooves and section A. The designation POLEA 210 3A summarizes those three variables: the outside diameter, the number of grooves and the belt profile. Section A corresponds to classic narrow-profile V-belts, suitable for transmitting power in tight spaces. Because it is in-house manufactured, EMMAR brand, the center bore and keyway can be machined according to the shaft where it is mounted.

It is used in equipment that needs to transmit motion between separate shafts: compressors, fans, centrifugal pumps, conveyor belts, mixers and machine tools. It also appears in air conditioning installations and in low and medium power transmission systems. Having 3 grooves, it allows up to three section A belts to be mounted in parallel, which distributes the load and gives room to adjust the transmitted power according to the equipment demand.

To correctly select a pulley of this type, take into account the pitch diameter, the number of grooves, the belt section and the shaft diameter. The pulley is mounted on the shaft with a keyway and fixed axially with a set screw or a suitable fastening system. It is important to verify alignment between pulleys to avoid irregular belt wear and vibration. Belt tension is adjusted according to the equipment manual or the belt manufacturer's recommendations.

If you need a pulley with a different number of grooves, another diameter or a different section, a nearby size or an equivalent can be requested. For that, it is best to send the part number POLEA 210 3A together with the shaft data: diameter, bore length and type of keyway. It also helps to indicate the belt to be used and the center distance. With that data, at MR Accesorios Industriales we evaluate the manufacturing or adaptation of a similar pulley.
