The POLEA 500 4C pulley is an industrial pulley with a 500 mm diameter and 4 grooves for section C belts. It is used to transmit power between shafts in equipment that works with high loads and moderate speeds, such as mills, pumps, fans and conveyors. Because it is in-house manufacturing, EMMAR brand, the machining and balancing are controlled so that the pulley rotates without vibration and with a correct fit on the shaft.

This item is a pulley with a 500 mm diameter, 4 grooves and section C. Section C accepts belts with a wider profile than sections A or B, so it withstands greater load per groove. The four grooves allow the power to be distributed across several belts, which reduces the stress on each one and extends the service life of the assembly. The pulley is manufactured at MR Accesorios Industriales and is supplied with the bore and keyway according to the size you need.

Typical applications for a 500 mm pulley with 4 section C grooves are drive equipment with significant reduction ratios: mills, mixers, high-flow pumps, industrial fans and belt conveyors. It is also used in agricultural machinery and in process lines where power must be transmitted from an electric motor or a gearbox to the working shaft, with a moderate final speed.

To mount this pulley, verify that the shaft diameter matches the bore and that the keyway fits without play. Align the pulleys with a straightedge or a laser to avoid uneven belt wear. Belt tension is adjusted according to the equipment manual; excessive tension stresses the bearings and low tension makes the belts slip. If the pulley is mounted on a shaft with bearings, it is advisable to check their condition before installing.

If you need a pulley with a different number of grooves, another diameter or a different section, send us the part number or the size shown on the equipment plate. We can also manufacture a custom pulley with the bore and keyway you require. For that, send us the shaft data, the belt you use and the drive ratio you are looking for. With that information we will quote the part that best suits you.

To order this pulley or an equivalent, write to us on WhatsApp and send the part number POLEA 500 4C. If you have doubts about the section or the number of grooves, attach a photo of the old pulley or the belt reference. That way we can confirm the size and send you the quote without delay.
