The 180 4C pulley is a V-belt drive pulley, section C, with four grooves and a 180 mm diameter. It is used to transmit power between parallel shafts in industrial equipment, where speed needs to be increased or reduced with a high-capacity belt. Because it is in-house manufacturing, EMMAR brand, the machining of the groove and the balancing are controlled. It is mounted on shafts with a keyway and aligned with the drive pulley so that the belt runs evenly.
This pulley has a 180 mm diameter, 4 grooves and section C. That combination defines how many C belts fit in the same plane and what drive ratio you can achieve depending on the diameter of the drive pulley. The groove is machined with the angle and depth that correspond to section C, so that the belt rests on the flanks and not on the bottom. The body is cast iron and the hub comes with a keyway for fastening to the shaft.
It is used in screw compressors, mills, mixers, centrifugal pumps, induced draft fans and conveyors. Also in woodworking machines, chippers and pumping equipment where the electric motor or gasoline engine is far from the working shaft. With four grooves the load is distributed among several belts, which allows transmitting more power without increasing the pulley diameter.
To mount it, check that the shaft has the diameter and keyway that correspond to the hub, and that the drive pulley is aligned in the same plane. Belt tension is adjusted with the motor tensioner or slide rail, not by forcing the pulley. If you are replacing an existing pulley, take the outside diameter, the number of grooves and the section; with that data the equivalent is found in the MR catalogue.
If you need a nearby size, a different diameter or more grooves, send us the part number POLEA 180 4C by WhatsApp along with a photo of the old pulley and the shaft measurement. With that, the MR Accesorios Industriales team sends you the quote. We can also evaluate machining the hub if the shaft has a special measurement.
MR Accesorios Industriales manufactures this pulley in the country, with dimensional control of the groove and the diameter. That allows replacing a worn pulley without changing the rest of the drive system. If you have doubts about the section or the number of grooves, ask us before ordering: a poorly selected pulley wears the belt and lowers the equipment's performance.

Frequently Asked Questions
- What does it mean that it is section C?
- Section C corresponds to a V-belt profile with greater width and height than sections A or B. The pulley has the groove machined with that profile, so it only accepts section C belts. It is not interchangeable with pulleys of another section.
- Can I request a pulley with another diameter or more grooves?
- Yes. MR manufactures drive pulleys in different sizes and numbers of grooves. Send the diameter, section and grooves you need by WhatsApp, and the technical team confirms whether it can be manufactured and sends you the quote.
- How do I know if this pulley replaces the one I have mounted?
- Compare the outside diameter, the number of grooves and the belt section. Also check the shaft diameter and the keyway. With that data and a photo of the original pulley, at MR they will tell you if this size is the equivalent.
