The POLEA 300 4A pulley is a V-belt drive pulley, manufactured by EMMAR Accesorios Industriales. It has a 300 mm diameter, 4 grooves and section A, which makes it suitable for driving several pieces of equipment at once from a single shaft line. It is used in machines that need to distribute power between different points: fans, pumps, compressors, conveyor belts and mixers. Because it is in-house manufactured, we can adjust the machining and finish according to what your assembly requires.

This item is a pulley with a 300 mm diameter, 4 grooves and section A. The POLEA 300 4A designation summarizes those three variables: size, number of grooves and belt profile. The grooves are machined for section A V-belts, and the body is formed so that the grooves are aligned with each other. It is a multi-groove pulley, designed to transmit from a single shaft to several belts in parallel, not for a single run.

Typical applications are drive lines with several outputs: industrial fans, centrifugal pumps, screw compressors, belt conveyors and mixing equipment. It is also used in machine tools and test benches where a fixed and repeatable transmission ratio is needed. With 4 grooves, it allows the load to be distributed among several belts, which reduces the stress on each one and improves the continuity of movement.

To mount and select this pulley, first check the shaft diameter and the fastening system: keyway, taper bushing or set screw, as applicable. Check that the belt section matches the groove and that the number of grooves is the same on the driving and driven pulleys. Alignment between pulleys is key so that the belts do not come off or wear on one side. Tension is adjusted according to the equipment manual or standard assembly practice.

If you need an equivalent or a nearby size, send us the part number POLEA 300 4A or the diameter, number of grooves and section you are using. With that data we can see whether there is a pulley of another size in the same series or whether it is better to manufacture one to measure. We can also review the bore machining and fastening so that it matches your shaft. The more complete the information, the faster we can give you a useful answer.
