The 550 3C pulley is a V-belt drive pulley, section C, with 550 mm diameter and three grooves. It is used to drive machine and equipment shafts where torque must be transmitted with several belts in parallel. It is in-house manufacturing, EMMAR Accesorios Industriales brand, which allows machining to be adjusted to the size and keyway type required by your application.

This item is a pulley with 550 mm diameter, 3 grooves and section C. The designation POLEA 550 3C summarizes those three data: size, number of grooves and belt profile. Section C corresponds to wide-profile V-belts, used when high power must be transmitted with few belts. Being in-house manufacturing, EMMAR brand, the machining of the bore, keyway and balancing are defined according to the shaft where it is mounted.

It is used in drives for mills, mixers, compressors, high-flow pumps, industrial fans and transmission lines in process plants. It also appears in lifting equipment and in agricultural or road machines working under demanding conditions. In all those cases, the three-groove pulley allows the load to be distributed among three belts, which reduces wear and provides margin if one belt fails.

To select it, take into account the power to be transmitted, the RPM of the motor shaft and driven shaft, and the pitch diameter required by the drive calculation. Verify that the bore and keyway match the shaft, and that balancing is adequate if the pulley will rotate at high speed. Alignment between pulleys and belt tension are key for the assembly to last.

If you need a size other than 550 mm, a different number of grooves or a different section, it can be manufactured to order. For that, send us the diameter, number of grooves, section and bore and keyway dimensions. We can also analyze a replacement if you have a worn or unidentified pulley. With that data, the technical team defines the machining and sends you the quote.
