The 240 4A pulley is a V-belt drive pulley manufactured by EMMAR Accesorios Industriales. It has a 240 mm diameter and 4 grooves for section A belts. It is used to transmit power between parallel shafts in industrial equipment, with the advantage of allowing various speed ratios depending on the diameter of the driving pulley. As it is in-house manufactured, it can be adapted to the needs of each assembly.

This pulley has a 240 mm diameter and 4 grooves for section A belts. The designation 240 4A summarizes these three characteristics: outer diameter, number of grooves and belt section. It is designed to be mounted on shafts with a keyway and secured with a set screw or with a taper bushing, as applicable. The machining of the grooves follows the usual tolerances for section A pulleys, so that the belt seats evenly along its entire length.

It is used in drives for machine tools, pumps, fans, compressors and conveyors. Also in factory equipment where revolutions need to be reduced or increased with a fixed ratio. Having four grooves, it allows mounting one, two, three or all four belts, which makes it possible to scale the transmitted power without changing the pulley. It is common to see it in production lines where a certain torque reserve is needed.

To choose it correctly, take into account the pitch diameter, the belt section and the number of grooves. Verify that the shaft has a compatible diameter and keyway, and that the pulley is aligned with the driving pulley to avoid uneven belt wear. Tension is adjusted according to the equipment manual or the belt manufacturer's recommendations. If space is limited, evaluate whether a smaller diameter or fewer groove pulley is preferable.

If you need a different size, we can manufacture a pulley with another diameter, another number of grooves or for another belt section. To request an equivalent, send us the original pulley part number, the section and number of grooves, and the shaft dimensions. With that data we will quote the option that best suits you. We can also guide you if you don't have the technical data sheet at hand.
