Description

EMMAR POLEA 480 3B is a pulleys reference, within Power transmission. Request a quote for POLEA 480 3B via WhatsApp or email with the quantity you need; we respond promptly with lead time and equivalents.

The 480 mm industrial pulley with 3 grooves, section B, is a power transmission component mounted on a machine shaft to transmit motion through V-belts. It is used in equipment that needs to maintain speed and torque with a stable transmission ratio, such as fans, pumps, compressors and conveyors. Its construction allows several grooves to be aligned in the same plane to distribute the load among the belts.

This item is a pulley with a 480 mm diameter, 3 grooves and section B. The designation POLEA 480 3B summarizes those three variables: the outer diameter, the number of grooves and the belt profile it accepts. Section B corresponds to classic-type V-belts, and the three grooves allow three belts to be installed in parallel on the same hub. It is an in-house manufactured part, EMMAR brand, designed to replace worn pulleys or to build a new drive from scratch.

Typical applications for a pulley of this size and number of grooves are medium- and high-power equipment: centrifugal fans, water pumps, screw compressors, belt conveyors and continuous process machines. In all those cases, the pulley works together with a smaller driving or driven pulley, and the ratio between the two defines the final speed of the equipment. It is also used in systems that need a certain power reserve, because the three grooves allow adding belts if the load increases.

To mount this pulley, check that the shaft has the diameter and keyway compatible with the hub bore, and that the driving pulley is aligned in the same plane. Belt tension is adjusted according to the equipment manual or the usual practice of the plant: if they are too loose, they slip; if they are too tight, they punish the shaft bearings. When selecting, take into account the power to be transmitted, the rotation speed and the diameter of the driving pulley. If you need to calculate the ratio, we can help you with the equipment data.

If the part number POLEA 480 3B does not exactly match what you need, you can request a nearby size or an equivalent. To do so, send us by WhatsApp the diameter, the number of grooves and the section of the original pulley, or directly a photo of the part and the shaft. With that data we check whether we have a pulley with similar characteristics or whether it is better to manufacture it. We can also guide you if the available space makes it necessary to change the number of grooves or the diameter.

MR Accesorios Industriales manufactures this pulley and sells it along with the rest of the power transmission line. If you want to request a quote, send the part number POLEA 480 3B by WhatsApp and we will reply with the commercial information. You can also ask about other sizes in the same series or about pulleys of a different section. We are in Buenos Aires, Argentina, and we handle technical inquiries from all over the country.

Frequently Asked Questions

What does the designation POLEA 480 3B mean?
The 480 indicates the pulley diameter in millimeters, the 3 the number of grooves and the B the V-belt section it accepts. It is a three-groove pulley for section B belts, with an outer diameter of 480 mm.
How do I know if this pulley replaces the one I have mounted?
Compare the outer diameter, the number of grooves and the belt section. If those three data match, the pulley is equivalent. If the diameter is different but the section and grooves are the same, a nearby size may work, but the transmission ratio changes.
Can I request a pulley with a different number of grooves or diameter?
Yes. Send us by WhatsApp the data of the pulley you need: diameter, grooves and section. With that information we quote you an in-house manufactured pulley with the required dimensions or offer you the closest one in the line.
