The 220 3A pulley is a V-belt drive pulley, manufactured by EMMAR Accesorios Industriales. It has a 220 mm diameter, 3 grooves and section A, which makes it suitable for driving several shafts at once with a single belt. It is used in machines that need to transmit power steadily, such as fans, compressors, pumps and conveyors. Being in-house manufactured, it can be adjusted to the needs of each equipment.
This item is a pulley with a 220 mm diameter, 3 grooves and section A. Section A corresponds to classic narrow-profile V-belts, and the 3 grooves allow mounting three belts in parallel on the same pulley. The 220 mm diameter defines the transmission ratio when combined with another pulley in the same system. The part is manufactured at MR Accesorios Industriales and is identified with the part number POLEA 220 3A.
Section A pulleys with multiple grooves are used in equipment where torque must be transmitted with some redundancy: if one belt fails, the others keep pulling. They appear in industrial fans, screw compressors, centrifugal pumps, conveyor belts and machine tools. They are also seen in air conditioning installations and in process equipment that runs many hours a day.
To mount a pulley like this, verify that the shaft has the correct diameter and key, and that the pulley bore matches. The alignment between drive and driven pulleys must be careful: angular or parallel misalignment wears the belts and bearings. Belt tension is adjusted according to the equipment manual. If you don't have the data, it is advisable to consult the machine manufacturer or us.
If you need an equivalent pulley or a nearby size, send us the full part number, the number of grooves and the section. It also helps to tell us the current outside diameter and the shaft diameter. With that data we can see if there is a pulley in our line that replaces the one you have. If it doesn't appear in the listing, a custom manufacturing can be evaluated.
To request a quote for the 220 3A pulley, send the part number by WhatsApp to MR Accesorios Industriales. If you have doubts about the section, the number of grooves or the diameter, write to us and we'll help you confirm that it is the right pulley for your equipment.

Frequently Asked Questions
- What does section A mean?
- Section A is a classic V-belt profile, with standardized top and bottom widths. Section A pulleys have grooves with that shape so the belt rests on the flanks. It is not interchangeable with belts of other sections, such as B or SPZ.
- Can I use this pulley with fewer than 3 belts?
- Yes, one or two belts can be mounted in the available grooves. The pulley will transmit less power than with all three belts, but it works. Keep in mind that the load distribution on the shaft changes if you use fewer grooves.
- How do I request a pulley with another diameter or number of grooves?
- Write to us on WhatsApp with the outside diameter, the number of grooves and the section you need. Also send us the shaft diameter and the type of key. With that data we'll tell you if we have a similar pulley or if it is better to manufacture it.
