The 270 mm industrial pulley with 2 grooves for section A is a power transmission component that mounts on shafts to drive V-belts. It is used in machines that need to transmit torque at a fixed speed ratio, such as fans, compressors, pumps and conveyors. Its diameter and number of grooves allow calculating the peripheral speed and the power to be transmitted according to the application. MR manufactures it with dimensional control to ensure correct belt seating and a long service life.

This item is a pulley with a 270 mm diameter, 2 grooves and section A. The designation POLEA 270 2A summarizes those three variables: the 270 mm outside diameter, the number of grooves (2) and the belt profile it accepts (section A). It is manufactured by EMMAR, which produces split plummer block housings, ANSI roller chains and pulleys, among other components. Section A corresponds to classic V-belts with a narrow profile, suitable for low and medium power transmissions.

Typical applications of a 2-groove section A pulley include centrifugal fans, screw compressors, centrifugal pumps, belt conveyors and machine tools. In all cases the goal is to transmit motion from an electric motor or a gearbox to the driven equipment, maintaining a constant transmission ratio. Having two grooves makes it possible to double the transmission capacity compared with a single-groove pulley, or to run with a single belt if the demand is lower.

To select this pulley correctly, take into account the pitch diameter, which is calculated from the outside diameter minus a constant that depends on the section. Check that the belt is section A and that the number of grooves matches the number of belts you plan to use. Mounting requires the shaft to have the correct diameter and the pulley to be aligned with the drive pulley to avoid uneven wear. Use a key or a similar fastening system according to the shaft design.

If you need a pulley with another size, another number of grooves or a different section, we can manufacture it or find an equivalent. To do so, send us the part number POLEA 270 2A or that of the original pulley by WhatsApp, together with the belt and shaft data. We can also advise you if you have doubts about the transmission ratio or the power to be transmitted. MR Accesorios Industriales manufactures custom pulleys and supplies power transmission components.
