The 280 6C pulley is a V-belt drive pulley, manufactured by EMMAR in section C with 6 grooves and a 280 mm diameter. It is used to transmit power between parallel shafts in industrial equipment, where a stable transmission ratio and good load capacity are required. Because it is in-house manufactured, MR controls the machining of the groove and the balancing, which results in even operation and less belt wear.

This item is a pulley with a 280 mm diameter, 6 grooves and section C. The designation POLEA 280 6C summarizes those three variables: the 280 mm outside diameter, the number of grooves (6) and the belt section it houses, C. The groove is machined so that the V-belt rests on the flanks, not on the bottom, which is how the force is transmitted. It is an in-house manufactured pulley, EMMAR brand, designed for continuous service in power transmission.

Typical applications are equipment with electric motors and parallel shafts: fans, centrifugal pumps, compressors, conveyor belts, mixers and machine tools. In all those cases the pulley receives the rotation from the motor and transmits it to the machine, or vice versa. Section C allows absorbing medium and high power with few grooves, and the 6 grooves provide margin to distribute the load among several belts, which extends the service life of the assembly.

To mount and select this pulley correctly, verify that the shaft diameter matches the hub bore and that the keyway is the right one. The pulley is fixed with a key and set screw or with a taper bushing, depending on the case. Check the alignment between pulleys with a straightedge or laser: a misalignment of a few degrees accelerates belt wear. Tension is adjusted according to the equipment manual; too loose slips, too tight stresses the bearings. If the pulley is mounted on a shaft that rotates fast, it is advisable to verify the balancing.

If you need an equivalent pulley or a nearby size, send us the full part number and the equipment data: shaft diameter, number of grooves, belt section and center distance. With that we can see if a pulley of another size fits or if it is better to manufacture it. We can also advise you on the type of bushing or the fixing system. The more precise the information, the faster we give you a useful answer.
