The 240 3A pulley is a V-belt transmission pulley, manufactured by EMMAR Accesorios Industriales. It has a 240 mm diameter and 3 grooves for section A belts, which allows transmitting motion between shafts with good load capacity and controlled speed. It is used in machines and equipment that need defined transmission ratios, with the advantage of a locally manufactured product and standardized sizes for replacement or new projects.

This item is a pulley with a 240 mm diameter, 3 grooves and section A. The designation POLEA 240 3A summarizes those three variables: size, number of grooves and belt type. Section A corresponds to classic V-belts, with a narrow profile, suitable for medium power and moderate peripheral speeds. Being of in-house manufacturing, EMMAR brand, the groove machining and balancing are controlled so the pulley rotates without vibrations and the belts seat evenly.

Typical applications include transmissions for machine tools, compressors, fans, centrifugal pumps, conveyor belts and process equipment. It is also used in the field, in agricultural implements and in workshops that assemble or repair machines with electric or combustion motors. Having 3 grooves allows mounting three section A belts in parallel, which distributes the load and provides margin if one belt fails, without completely stopping the transmission.

To correctly select the pulley, take into account the pitch diameter, the number of grooves, the belt section and the type of keyway or shaft fixing. Check that the driving and driven pulleys have the same section and that the desired transmission ratio is compatible with the available diameters. During mounting, align the pulleys with a straightedge or laser, tension the belts according to the manufacturer's manual and check shaft parallelism to avoid premature wear.

If you need an equivalent pulley or a nearby size, send us the part number POLEA 240 3A or the transmission data: diameter, grooves, section and shaft type. We can also manufacture to measure if the volume justifies it. Write to us on WhatsApp and we will quote the pulley that best fits your equipment, with technical advice so you don't buy more or less than you need.
