The 480 5C pulley is a power transmission pulley of in-house manufacturing, EMMAR brand, with 480 mm diameter and 5 grooves for section C belts. It is used to drive parallel shafts in equipment that requires several belts working together, such as mills, compressors, high-flow pumps and industrial fans. Being of in-house production, MR controls the machining of the groove and the balancing, two factors that define how long the belt lasts and how much vibration the system transmits.

This item is a pulley of 480 mm diameter, with 5 grooves and section C. The designation POLEA 480 5C summarizes those three data: size, number of grooves and belt profile. Section C corresponds to wide classical type belts, the ones used when power must be transmitted with few grooves or when the pulley diameter does not allow mounting a smaller profile. The five grooves allow distributing the load among several belts, which reduces the stress on each one and extends the service life of the assembly.

The typical applications of a pulley of this size and number of grooves are in the drive of continuous process equipment: mills, mixers, screw compressors, high-flow centrifugal pumps, induced draft fans and conveyors. In all those cases the aim is to transmit high power with a single motor shaft and keep the output speed within a stable range. The 5-groove pulley is chosen when the calculation indicates that several belts are needed to cover the power without oversizing the diameter.

To mount and select this pulley, take into account the pitch diameter, which is the one used to calculate the transmission ratio, not the outside diameter. Verify that the keyway and the hub bore match the shaft, and that the pulley is aligned with the driving pulley: a misalignment of a few degrees wears the grooves unevenly. Also check the belt tension and the condition of the grooves before starting up. If the equipment works with vibration, it is advisable to check the balancing of the pulley.

If you need a nearby size, another diameter or a pulley with a different number of grooves, you can request an equivalent or an in-house manufacturing variant. For that, send the part number POLEA 480 5C or the part number of the pulley you are replacing, together with the belt section and the number of grooves that the equipment needs. With those data, the closest option within MR's pulley line is found or custom manufacturing is evaluated.

MR Accesorios Industriales manufactures this pulley and sells it together with the rest of the power transmission line.
