The 480 5C pulley from EMMAR is a 480 mm diameter, 5-groove power transmission pulley for section C belts. It is manufactured in-house, which means the groove machining and balancing are controlled directly. This pulley is used to drive parallel shafts in equipment that relies on multiple belts working together, such as mills, compressors, high-flow pumps and industrial fans.

The part number POLEA 480 5C tells you the three key details: 480 mm diameter, 5 grooves, and section C belt profile. Section C is a wide classical belt, chosen when power must be transmitted with few grooves or when the pulley diameter does not allow a smaller profile. With five grooves, the load is spread across several belts, reducing stress on each one.

This size and groove count is common in continuous process drives: mills, mixers, screw compressors, high-flow centrifugal pumps, induced draft fans and conveyors. In these cases, the goal is to transmit high power from a single motor shaft while keeping output speed stable. A 5-groove pulley is selected when calculations show that several belts are needed without increasing the diameter beyond what the system allows.

When selecting or mounting this pulley, use the pitch diameter for ratio calculations, not the outside diameter. Confirm that the hub bore and keyway match the shaft, and that the pulley is aligned with the driving pulley; even a few degrees of misalignment will wear the grooves unevenly. Check belt tension and groove condition before startup. If the equipment runs with vibration, check the pulley's balancing.

If you need a different diameter or number of grooves, MR can evaluate an equivalent or an in-house manufacturing variant. Send the part number POLEA 480 5C or the part number of the pulley you are replacing, along with the belt section and required number of grooves. The team will review it within MR's pulley line.
