The 480 4C pulley is a V-belt transmission pulley, manufactured by EMMAR Accesorios Industriales. It has 480 mm diameter, 4 grooves and section C, which makes it suitable for transmitting power in medium and high demand equipment. It is used in industrial machines, mills, conveyor belts and ventilation systems where a stable transmission ratio and good belt grip are needed. Being of in-house manufacturing, variants of machining and balancing can be requested.

This pulley has 480 mm diameter, 4 grooves and section C. Section C corresponds to wide profile V-belts, and the 4 grooves allow mounting four belts in parallel to distribute the load. The 480 mm diameter defines the transmission ratio together with the driven pulley. It is a piece of cast iron or machined steel, depending on the order, with turned grooves so that the belt seats evenly. It is manufactured at MR and identified with the part number POLEA 480 4C.

It is used in belt transmissions of industrial machines: mills, mixers, conveyor belts, fans, compressors and pumping equipment. It also appears in production lines where speed must be reduced or increased between a motor and a working shaft. Having four grooves, it is common in drives that require redundancy or greater torque capacity without increasing the diameter. It is a general-purpose pulley for maintenance and replacement of existing equipment.

To select it, take into account the pitch diameter, the number of grooves and the belt section. Verify that the keyway and the shaft bore match the equipment shaft. Balancing is important if the pulley rotates at high revolutions: it is advisable to ask whether it is supplied statically or dynamically balanced. Also check the alignment between pulleys, because a misalignment wears the grooves and shortens the life of the belts. If the original equipment uses section C, keep that section so as not to change the belts.

If you cannot find the exact part number or need a nearby size, send us the equipment data: diameter, number of grooves, section and type of bore. We can manufacture a custom pulley or adapt an existing one. It is also advisable to send a photo or a sketch with the shaft and keyway dimensions. With those data, the technical team of MR Accesorios Industriales evaluates the best option and sends you the quote.

To request it, write to us via WhatsApp with the part number POLEA 480 4C or with the dimensions of your current pulley. If you have doubts about the section or the number of grooves, send a photo of the old pulley and the belt it uses. That way we confirm whether this pulley is the one you need or whether a variant is advisable. The service is direct and straightforward.
