The 550 5C pulley is a V-belt drive pulley, manufactured by EMMAR Accesorios Industriales. It has a 550 mm diameter and 5 grooves for section C belts, which makes it suitable for transmitting power in medium and high-demand equipment. It is used in industrial machines, compressors, mills, pumps and ventilation systems where a stable transmission ratio and good belt grip are needed. As it is of in-house manufacturing, the bore machining and keyway can be adapted according to the equipment shaft.

This pulley has a 550 mm diameter, 5 grooves and section C. It is a cast iron or steel pulley, depending on use, with grooves machined for section C V-belts. The number of grooves allows adding the transmission capacity of several belts in parallel, which provides redundancy and distributes the load. The 550 mm diameter defines the tangential speed and the torque the assembly can handle. It is supplied with the bore and keyway to be defined according to the equipment shaft, so it is advisable to indicate those measurements at the time of inquiry.

It is used in power transmissions of industrial machines: screw compressors, mills, mixers, centrifugal pumps, induced draft fans and process equipment. It also appears in production lines where a constant speed must be maintained with load variations. Having 5 grooves, it is common to see it in applications where the aim is to reduce vibration and slippage, or where a certain power reserve is required in case a belt fails. It is a common replacement part in industrial maintenance.

To select it, take into account the pitch diameter, the belt section, the number of grooves and the type of bore. Verify that the driving and driven pulleys have the same section and that the transmission ratio is adequate for the speed you need. Mounting must be done with the pulley well aligned with the other pulley, using a gauge or ruler, and with the keyway correctly placed. Belt tension is adjusted according to the equipment manual or the recommended practice for section C belts. Check the condition of the grooves before mounting: burrs or wear accelerate belt wear.

If you need an equivalent pulley, send us the original pulley code, the number of grooves and the section. It also helps if you send us the outside or pitch diameter, the shaft diameter and the groove width. With that data we will indicate whether the 550 5C pulley is suitable or whether it is better to machine a similar pulley. As it is in-house manufacturing, we have flexibility to adjust the bore, keyway and balancing according to what your equipment requires. The pulley does not need to be exactly the same: we can find a way for it to fulfill the function.
