The POLEA 500 4B pulley is a V-belt drive pulley, manufactured by EMMAR Accesorios Industriales. It has a 500 mm diameter and 4 grooves for section B belts. It is used to transmit power between parallel shafts in industrial equipment, with the advantage that, being in-house manufactured, we can adjust the machining to what your machine needs. If you are replacing a worn pulley or assembling a new drive, this model works for transmission ratios with four belts in parallel.
This item is a pulley with a 500 mm diameter, 4 grooves and section B. These are the three data points that define the model: the 500 mm outer diameter, the four grooves where the belts rest, and section B, which corresponds to an industrial-type V-belt profile. The pulley is machined at MR with the balancing and concentricity needed to rotate at the usual speeds of this type of drive. Being in-house manufactured, we do not depend on an external catalog to deliver the part with the dimensions shown on the drawing.
Typical applications of a 500 mm pulley with 4 grooves section B are power transmissions in process equipment: industrial fans, centrifugal pumps, screw compressors, conveyor belts and production machines in general. It is also used in the field, in agricultural implements and irrigation equipment where torque needs to be transmitted with several belts to distribute the load. In all these cases, the pulley works together with a shaft, a hub and a fastening system that must be defined according to the machine.
To properly mount and select this pulley, take into account the shaft diameter and the type of fastening: the outer diameter and number of grooves are not enough. Verify that the belt section is B and that the number of grooves matches the number of belts you will use. Also check the alignment between pulleys and belt tension, because the service life of the assembly depends on that. If the pulley will rotate at high speed, it is advisable to check balancing and groove condition before putting it into service.
If you need an equivalent or a nearby size, the most practical thing is to send us the full part number or the drawing of the original pulley. With the diameter, number of grooves and section we can see if there is an in-house manufactured pulley that replaces the one you have. We can also evaluate special machining, such as the shaft bore, keyway or hub type, as long as you provide that data. The pulley does not have to be our brand: if you give us the dimensions, we will review it.
To request a quote for the POLEA 500 4B or any other transmission pulley, send the part number via WhatsApp to MR Accesorios Industriales. If you have doubts about the section, number of grooves or diameter, write to us anyway: we will help you identify the pulley you need and send you the quote. We work with in-house manufacturing and also with lines of bearings, housings, seals and lubricants so you can solve the complete transmission in one place.

Frequently Asked Questions
- What does POLEA 500 4B mean?
- It means a pulley with a 500 mm diameter, 4 grooves and section B. It is the abbreviated way of naming the model: the number indicates the diameter and the letter the belt profile. With that data the pulley can already be identified in the MR catalog.
- Can I request a pulley with a different diameter or number of grooves?
- Yes. Being in-house manufactured, we can evaluate other sizes and numbers of grooves. Send us via WhatsApp the diameter, section and number of grooves you need, and we will tell you if we can manufacture it or if a standard pulley is better.
- How do I know if this pulley replaces the one I have installed?
- Compare the outer diameter, number of grooves and belt section. Also check the shaft bore and the type of fastening. If that data matches, it is very likely to work. If you are not sure, send us a photo or the drawing and we will verify it.
