This item is a pulley of 250 mm diameter, with 4 grooves and section C. The designation POLEA 250 4C summarizes those three variables: size, number of grooves and belt profile. Section C corresponds to wide-profile V-belts, suitable for transmitting medium and high power at moderate transmission ratios. Being in-house manufactured, EMMAR brand, the bore, keyway and balancing can be machined according to the shaft and working RPM.

Typical applications are drives for mills, mixers, compressors, centrifugal pumps, fans and conveyors. In these machines, the 4-groove pulley allows the load to be distributed among four belts, which reduces individual tension and improves the service life of the assembly. It is also used in production machines where a constant rotation speed must be maintained against load variations.

To select correctly, take into account the pitch diameter, number of grooves, belt section and shaft diameter. Verify that the pulley is compatible with the belt type and that the bore and keyway match the shaft. Assembly must be done with the pulley clean and free of burrs, aligning the pulleys with a straightedge or laser to avoid uneven belt wear.
