The POLEA 150 5B pulley is a V-belt drive pulley, manufactured by EMMAR Accesorios Industriales. It has a 150 mm diameter, 5 grooves and section B. It is used to transmit power between parallel shafts in machines and industrial equipment, where speed needs to be multiplied or reduced while maintaining torque. Its in-house construction allows the machining of the bore, keyway and balancing to be adapted according to the equipment where it is mounted.

This item is a pulley of 150 mm in diameter, with 5 grooves and section B. The designation POLEA 150 5B summarizes those three variables: size, number of grooves and belt profile. Section B corresponds to classic V-belts with a B profile, and the 5 grooves allow five belts to be mounted in parallel on the same pulley. It is an in-house manufactured piece, EMMAR brand, designed to be integrated into belt drives of industrial equipment.

It is used in fans, centrifugal pumps, compressors, conveyor belts, mixers and machine tools. Also in process equipment where a fixed transmission ratio is required between a motor and a driven shaft. Because it has 5 grooves, it is suitable for medium and high power within section B, as long as the drive calculation confirms it. It is common in food, chemical and ceramic plants and in maintenance workshops.

To mount it, verify that the shaft bore matches the pulley's inner diameter and that the key fits without play. Align the pulleys with a straightedge or laser to avoid uneven belt wear. Tension is adjusted according to the equipment manual or the mechanic's criteria: too loose slips, too tight strains the bearings. If you need to change the transmission ratio, you can vary the diameter of the driving or driven pulley, respecting the grooves and the section.

If you cannot find the exact size, we can manufacture a pulley with the diameter, number of grooves and section you need. To do so, send us the code POLEA 150 5B or the equipment data: pitch diameter, grooves, belt section, shaft diameter and type of keyway. We can also evaluate a nearby size if space allows. The idea is for the pulley to fit the equipment without risky adaptations.
