The EMMAR 480 3B is a three-groove pulley for section B V-belts, with a 480 mm diameter. It mounts on a machine shaft and transfers motion through the belts, keeping a stable ratio between speed and torque. Fans, pumps, compressors and conveyors are common hosts for this kind of drive. Multiple grooves sit in one plane so the load can be shared across the belts.

The code POLEA 480 3B packs the key selection data: 480 mm diameter, 3 grooves, section B. That section accepts classic V-belts, and the three grooves let you run three belts side by side on the same hub. This pulley is manufactured in-house under the EMMAR brand. It serves as a replacement for a worn unit or as a component in a new drive build.

You will typically find a pulley of this size and groove count on medium- to high-power equipment: centrifugal fans, water pumps, screw compressors, belt conveyors and continuous-process machines. In each case it pairs with a smaller pulley, and the diameter relationship between the two sets the final equipment speed. The three grooves also give some room to add belts if the load grows.

Before mounting, confirm the shaft diameter and keyway match the hub bore, and that the mating pulley is aligned in the same plane. Set belt tension according to the equipment manual or your plant practice: loose belts slip, while over-tight belts put extra load on the shaft bearings. For selection, factor in the power to transmit, the rotation speed and the diameter of the driving pulley. If you need to work out the ratio, we can help with the equipment data.

If POLEA 480 3B is not an exact fit for your application, ask about an equivalent. Send the diameter, groove count and section of the original pulley by WhatsApp, or a photo of the part and the shaft. With that information we can propose a pulley with similar characteristics or manufacture it. We can also advise if space constraints mean changing the number of grooves or the diameter.
