The 330 4C pulley is a V-belt drive pulley, section C, with a 330 mm diameter and 4 grooves. It is used to drive machine shafts from a motor, transmitting torque through belts. It is an in-house manufactured part, EMMAR Accesorios Industriales brand, designed for applications that require a large-diameter pulley with several grooves to distribute the load across belts.
This pulley has a 330 mm diameter, 4 grooves and section C. Section C corresponds to wide-profile V-belts, and the 4 grooves allow four belts to be installed in parallel on the same pulley. The 330 mm diameter defines the drive ratio when combined with another pulley in the same system. It is an in-house manufactured pulley, EMMAR brand, not a third-party product.
It is used in equipment that needs to transmit power with section C belts: compressors, mills, mixers, high-flow pumps, industrial fans and continuous-process machines. Also in drives where the goal is to reduce motor speed and increase torque on the driven shaft. With 4 grooves, it accepts more than one belt to distribute the load and keep running if one breaks.
To mount it, check that the shaft and keyway match the pulley bore, and that the driving and driven pulleys are aligned. The number of grooves must be the same on both pulleys so that all belts work. Tension is adjusted according to the belt type and the center distance. If you are replacing a pulley, compare diameter, section and number of grooves before ordering it.
If you can't find the exact part number or need a nearby size, send us the part number, diameter, section and number of grooves. A photo of the old pulley or the data of the belt it uses also works. With that data we can see whether there is an equivalent pulley in the in-house manufacturing line or whether it is better to make it to order.
To request a quote for this pulley or a similar one, write to us on WhatsApp with the part number POLEA 330 4C. If you have questions about mounting or selection, the technical team at MR Accesorios Industriales helps you define the pulley that matches your drive.

Frequently Asked Questions
- What does section C mean on a pulley?
- Section C is the V-belt profile that fits into the pulley groove. It defines the width and depth of the groove. A section C pulley only works with section C belts; it is not compatible with belts of other sections.
- Can I use fewer belts than grooves?
- Yes, but the transmission capacity drops. Each extra groove distributes the load. If you use fewer belts than the pulley allows, check that the power to be transmitted does not exceed the capacity of the installed belts.
- How do I order a pulley in another size?
- Send the diameter, section, number of grooves and the type of bore or keyway by WhatsApp. With that data we tell you whether there is an equivalent pulley in the in-house manufacturing line, EMMAR brand, or whether it can be made to order.
