The POLEA 270 3C pulley is an industrial pulley of in-house manufacturing, EMMAR Accesorios Industriales brand, designed to transmit power using section C V-belts. It has a 270 mm diameter and 3 grooves, which allows building drives with several belts in parallel on the same shaft. It is used in equipment that needs to move loads at controlled speed with good grip, such as fans, pumps, compressors and conveyors. Because it is in-house production, you can inquire about sizes and configurations within the same line.

This item is a pulley with a 270 mm diameter, 3 grooves and section C. The POLEA 270 3C designation summarizes those three variables: the working outside diameter, the number of grooves and the belt profile it accommodates. Section C corresponds to wide-profile V-belts, typical of drives handling medium and high power. The three grooves allow distributing the load among several belts, which reduces the stress on each one and improves drive continuity.

Typical applications of a 3-groove section C pulley appear in permanent plant equipment: centrifugal fans, process pumps, screw compressors, mills, mixers and belt conveyors. In all those cases the goal is to transmit motion from an electric motor to the working shaft with a stable transmission ratio. It is also used in agricultural machinery and in material handling equipment where the pulley is exposed to dust and weather.

To mount and select this pulley correctly, verify that the diameter and number of grooves match the existing drive, that the keyway and shaft diameter are compatible and that the belt section is C. Check the alignment between pulleys with a straightedge or laser: misalignment accelerates belt and bearing wear. Tension must be the one recommended by the belt manufacturer, neither loose nor excessive. If the pulley is mounted on a shaft with bearings, it is advisable to check the condition of those bearings before installing.

If you need an equivalent or a nearby size, the most practical thing is to send us the full part number, a photo of the pulley and, if possible, the shaft diameter and the belt section you use. With that data we can verify whether there is a pulley in the same line with another diameter or a different number of grooves. We can also guide you if the available space requires changing the transmission ratio. The idea is that you don't buy a pulley that then doesn't fit or doesn't match.
