The 220 3C pulley is a V-belt drive pulley, section C, with three grooves and a 220 mm diameter. It is used to drive parallel shafts in equipment where power needs to be distributed across several belts, such as fans, compressors, pumps and conveyors. Because it is in-house manufactured, EMMAR brand, the bore and keyway machining can be adjusted to suit the shaft it is mounted on.

This item is a pulley with a 220 mm diameter, 3 grooves and section C. The designation POLEA 220 3C sums up those three variables: size, number of grooves and belt profile. Section C corresponds to wide-profile V-belts, the ones used when more torque has to be transmitted than with a section A or B. The three grooves allow the load to be distributed across three belts, which extends the service life of the assembly and reduces the demand on each run.

Typical applications are equipment with parallel shafts and medium center distances: centrifugal fans, screw compressors, centrifugal pumps, screens, belt conveyors and continuous process machines. In all those cases the pulley is mounted on the shaft of the driven equipment or the motor, and works together with a smaller-diameter pulley at the other end. It is also used in drives where a certain elasticity is needed to absorb starts with inertia.

To select this pulley properly, take into account the pitch diameter, the number of grooves and the belt section. Section C is not interchangeable with A or B: the groove has a different geometry. Also check the bore diameter and the hub length, because the pulley's fit on the shaft and its alignment with the drive pulley depend on that. Angular or parallel misalignment wears out the belts and the equipment's bearings. If the shaft is keyed, the pulley is machined with the corresponding keyway.

If you need a nearby size, another diameter or a different number of grooves, send us the part number POLEA 220 3C by WhatsApp and we'll quote you. We can also manufacture the pulley with the bore and keyway to your shaft dimensions. If you have doubts about the belt section, send us the data of the belt you use or the designation of the original pulley and we'll verify it. We have more than 80 years in power transmission, so ask us with no obligation.

MR Accesorios Industriales manufactures this pulley at its plant and sells it direct, with no intermediaries. That makes it possible to adjust the machining to what each piece of equipment needs and to answer technical questions with the factory at hand. If you are replacing a worn pulley, send us a photo or the old part number and we'll help you identify the replacement. Write to us on WhatsApp and we'll quote you.
