The 320 4C pulley is a V-belt drive pulley, section C, with a 320 mm diameter and 4 grooves. It is used to transmit power between parallel shafts in industrial equipment, where a stable transmission ratio and good load capacity are required. It is in-house manufacturing, EMMAR Accesorios Industriales brand, which allows machining and balancing to be controlled. It is mounted on shafts with a keyway and aligned with the drive pulley to prevent premature wear of belts and bearings.

This item is a pulley with a 320 mm diameter, 4 grooves and section C. The designation POLEA 320 4C summarizes those three variables: the outside diameter, the number of grooves and the belt profile it accepts. Section C corresponds to type C V-belts, which are used in medium and high power transmissions. Because it is in-house manufacturing, EMMAR brand, it can be replaced with the same dimensions and machining characteristics.

It is used in belt drives on industrial machines and equipment: compressors, fans, pumps, conveyor belts, mixers and mills, among others. It also appears in test benches and process equipment where speed needs to be varied by changing pulleys. Having 4 grooves allows the power to be distributed among several belts, which reduces the individual load and improves the reliability of the assembly.

To mount it, check that the shaft has the correct diameter and keyway, and that the pulley sits well supported and centered. Alignment with the drive pulley is key: angular or parallel misalignment accelerates wear on belts and bearings. It is also advisable to check belt tension according to the equipment manual. If you are replacing an existing pulley, use the diameter, number of grooves and section as a reference.

If you need a different size or an equivalent pulley, send us the full part number or the current dimensions: diameter, grooves, section and shaft diameter. With that data we can identify the pulley that best suits your drive. We can also manufacture a custom pulley if the equipment requires it. The idea is that you don't end up with a machine down because of a pulley you can't find.
