The 480 4C pulley is a V-belt drive pulley manufactured by EMMAR Accesorios Industriales. It has a 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 required. As it is in-house manufactured, machining and balancing variants can be requested.

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

It is used in belt drives of industrial machines: mills, mixers, conveyor belts, fans, compressors and pumping equipment. It also appears in production lines where speed needs to be reduced or increased between a motor and a working shaft. With 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 misalignment wears the grooves and shortens belt life. If the original equipment uses section C, keep that section so you don't have to change the belts.

Send us the equipment data: diameter, number of grooves, section and bore type. 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 that data, the technical team at MR Accesorios Industriales evaluates the best option and sends you the quote.

To order it, write to us on WhatsApp with the code POLEA 480 4C or with the measurements 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 can tell you whether this pulley is the one you need or whether a variant is better. Service is direct and straightforward.
