The 270 1B pulley is a V-belt drive pulley, manufactured by EMMAR Accesorios Industriales. It has a 270 mm diameter, a single groove and section B. It is used to transmit motion between parallel shafts in industrial machines and equipment, where a simple and reliable transmission ratio is needed. As it is in-house manufactured, we control the machining and finish so that it fits the shaft without problems and guides the belt well.

This item is a pulley with a 270 mm diameter, 1 groove and section B. The designation POLEA 270 1B summarizes those three characteristics: the outer diameter, the number of grooves and the belt profile it accepts. Section B corresponds to type B V-belts, widely used in industrial power transmissions. The groove is machined so that the belt seats evenly and does not come off during operation.

It is used in fans, pumps, compressors, conveyor belts and machine tools that run on electric motors and need to reduce or increase the speed of the driven shaft. It also appears in factory equipment and production lines where pulleys are replaced due to wear or a change in ratio. It is a common part in industrial maintenance because a misaligned pulley or one with a worn groove generates vibration, noise and premature belt wear.

To mount it, verify that the shaft diameter matches the pulley bore and that the key fits without play. The pulley must be aligned with the drive pulley: a misalignment of a few degrees accelerates belt wear. Tension is adjusted according to the equipment manual or the belt manufacturer's recommendation. If the pulley runs at high revolutions, it is advisable to check the balance. When selecting, take into account the power to be transmitted, the speed and the number of grooves needed.

If you need a pulley with another size, another number of grooves or a different section, we can manufacture it. Send us the part number POLEA 270 1B or the data of the original pulley —diameter, grooves, section and bore diameter— and we will quote an equivalent or a nearby size. We can also evaluate the machining of the bore and keyway according to your shaft. The more data you provide, the faster we respond.

MR Accesorios Industriales manufactures this pulley in Argentina and sells it together with belts, bushings and other transmission components.
