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 since it is in-house manufactured we can adjust the machining to what your machine needs. If you are replacing a worn pulley or setting up 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. Those 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. Since it is in-house manufactured, we do not depend on an external catalogue to deliver the part with the dimensions shown on the drawing.

Typical applications of a 500 mm pulley with 4 section B grooves are power transmissions in process equipment: industrial fans, centrifugal pumps, screw compressors, conveyor belts and production machinery 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 those cases, the pulley works together with a shaft, a hub and a fastening system that must be defined according to the machine.

To mount and correctly 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 are going to use. Also check the alignment between pulleys and the belt tension, because the service life of the assembly depends on that. If the pulley is going to rotate at high speed, it is advisable to check the balancing and the condition of the grooves before putting it into service.

If you need an equivalent, 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, the keyway or the type of hub, 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 drive pulley, send us 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 drive in one place.
