The POLEA 150 5C pulley is a V-belt drive pulley, section C, with a 150 mm diameter and 5 grooves. It is used to transmit power between parallel shafts in industrial equipment: compressors, fans, pumps, mills and conveyors. As it is in-house manufactured, EMMAR brand, it is machined with dimensional control on the pitch diameter and the grooves, so that the pulley-belt assembly runs aligned and with correct contact in each groove.

This item is a pulley with a 150 mm diameter, 5 grooves and section C. The POLEA 150 5C designation summarizes those three data points: size, number of grooves and belt profile. Section C corresponds to wide-profile V-belts, suitable for transmitting high power at moderate drive ratios. Multiple grooves allow the load to be distributed among several belts, so the pulley works with less stress per groove and allows the transmitted power to be adjusted according to how many belts are mounted.

Typical applications are drives of machines with parallel shafts: centrifugal fans, screw compressors, centrifugal pumps, screens, mills, mixers and belt conveyors. It is also used in gear reducers and transmission boxes where a fixed ratio between the motor and the driven equipment is needed. In all cases it is advisable to verify that the diameter of the driving pulley is equal to or greater than the minimum recommended for section C, so as not to force the belt or shorten its service life.

For mounting, check that the keyway and the shaft are clean and free of burrs, and that the pulley fits with a fit that does not require hammering. Alignment between pulleys is checked with a straightedge or laser: angular or parallel misalignment accelerates wear on the belts and the grooves. Tension is adjusted according to the equipment manual or with a tension gauge; a belt that is too loose slips and one that is too tight loads the shaft bearings. If the pulley is mounted with a taper bushing, respect the screw torque indicated by the bushing manufacturer.

If you need a pulley with a different number of grooves, another diameter or a different section, send us the part number or the designation marked on the part. We can also evaluate an equivalent if you send us the equipment data: pitch diameter, number of grooves, belt section, shaft diameter and mounting type. With that data we verify the part that best suits your drive.
