The POLEA 380 5B pulley is an in-house manufactured power transmission pulley, EMMAR brand, with a 380 mm diameter, 5 grooves and section B. It is used to transmit motion between shafts by means of V-belts, in machines and equipment that require defined transmission ratios. Its construction allows mounting on shafts with keyway and fastening with set screws or taper bushings, as applicable.

This item is a pulley with a 380 mm diameter, 5 grooves and section B. Section B corresponds to V-belts with a B profile, and the 5 grooves allow transmitting more power than a pulley with fewer grooves. The designation POLEA 380 5B summarizes those three variables: diameter, number of grooves and section. It is an in-house manufactured part, EMMAR brand, designed to replace standard pulleys in industrial equipment.

It is used in belt drives of machine tools, compressors, fans, pumps, mills, conveyor belts and process equipment. Also in installations where the transmission ratio must be changed or a worn pulley replaced. Being section B with 5 grooves, it is suitable for medium and high power within that section, provided the drive calculation confirms it.

To mount it, verify the shaft diameter and the type of fastening: keyway, set screw or taper bushing. Check the alignment between pulleys to avoid uneven belt wear and vibrations. Belt tension is adjusted according to the equipment manual or the belt manufacturer's recommendations. If you are replacing an existing pulley, compare diameter, grooves, section and bore type before ordering.

If you need a nearby size or an equivalent, send us the part number POLEA 380 5B via WhatsApp along with the shaft diameter, the type of fastening and a photo of the old pulley if you have it. With that data we can confirm whether there is a pulley in the same series with another diameter or number of grooves, or whether it is better to manufacture it to measure. We can also advise you on the compatible belt.
