The 420 6C pulley is a V-belt drive pulley, section C, with a 420 mm diameter and 6 grooves. It is used to drive shafts at different speeds in industrial equipment, where power needs to be transmitted reliably and with low maintenance. Because it is in-house manufactured, EMMAR brand, the machining and balancing are controlled so the belt seats properly and lasts.

This item is a pulley with a 420 mm diameter, 6 grooves and section C. Section C corresponds to V-belts with a wide profile, typical of medium and high power. The multiple grooves allow several belts to be mounted in parallel on the same pulley, so that the power is distributed among all of them. The 420 mm diameter defines the transmission ratio when combined with another pulley in the same system.

It is used in drives for mills, mixers, compressors, centrifugal pumps, fans and conveyors. It also appears in machines for wood, plastic and food, where the motor is far from the working shaft. In those cases, the 6-groove section C pulley allows the movement to be carried with few losses and absorbs vibrations typical of startup.

To mount it, check that the shaft and the keyway are clean and free of burrs, and that the pulley fits with the correct fit. Align the pulleys with a straightedge or a laser before tensioning the belts: misalignment accelerates wear on the grooves and the belts. Tension is adjusted according to the equipment manual; if it is loose, it slips, and if it is too tight, it punishes the shaft bearings.

If you need another size, another number of grooves or a different section, send us the equipment data or the designation of the original pulley. With the diameter, the grooves and the section we can locate the equivalent part or a neighboring size within the same line. We can also check the keyway and the type of bushing if the mounting requires it.

MR Accesorios Industriales manufactures this pulley and sells it with its own power transmission line.
