The 350 4A pulley is a V-belt transmission pulley, manufactured by EMMAR Accesorios Industriales. It has a 350 mm diameter, 4 grooves and section A, which makes it suitable for transmitting power in equipment that works with belts of that section. It is used in industrial machines, fans, compressors and transmission systems where a multi-groove pulley is needed. As it is in-house manufactured, variants of machining and balancing can be requested.

This pulley is identified as POLEA 350 4A. Its main data are: 350 mm size, 4 grooves and section A. Section A corresponds to classic-profile V-belts, and the 4 grooves allow up to four belts to be mounted on the same pulley to distribute the load. The 350 mm diameter defines the transmission ratio when combined with another pulley in the same system. It is an in-house manufactured part, EMMAR brand, designed to replace equivalent pulleys in existing equipment.

Typical applications of a 4-groove section A pulley with a 350 mm diameter include industrial fans, screw compressors, centrifugal pumps, conveyor belts and machine tools. In all these cases, the goal is to transmit torque from an electric motor or a gear reducer to the driven equipment, with the possibility of regulating speed by changing the diameter of the driving or driven pulley. It is also used in process equipment where a certain elasticity in the transmission is required.

To select and mount this pulley, take into account the belt section: it must be A, because the grooves are machined for that profile. Verify that the 350 mm diameter is compatible with the available space and with the desired transmission ratio. Check the alignment between pulleys and the belt tension: poor alignment accelerates wear on grooves and belts. If the equipment works with vibrations, it is advisable to evaluate the balancing of the pulley. The keyway and bore diameter are defined according to the equipment shaft.

If you need an equivalent pulley or a nearby size, the most practical thing is to send us the part number POLEA 350 4A or the equipment data: diameter, number of grooves, section and shaft diameter. With that data we can verify whether this pulley fits or whether it is better to manufacture a variant. As it is in-house manufactured, MR can adjust the bore, keyway and balancing according to what the assembly requires. We can also advise you if the space does not allow 350 mm.

To request a quote for this pulley or ask about a similar size, send the part number POLEA 350 4A by WhatsApp to MR Accesorios Industriales. If you have an old pulley, a photo or a drawing with the main dimensions, even better: that way we confirm the equivalence without hassle. We handle technical inquiries Monday through Friday.
