The 330 5B pulley is a V-belt drive pulley, section B, with a 330 mm diameter and 5 grooves. It is used to drive machine shafts from a motor, transmitting torque by means of belts. It is an in-house manufactured part, EMMAR Accesorios Industriales brand, designed for replacements and new assemblies in plants, factories and production lines where a stable transmission ratio and good belt support are needed.

This item is a pulley with a 330 mm diameter, 5 grooves and section B. The designation POLEA 330 5B summarizes those three data points: the outer diameter, the number of grooves and the belt profile it accommodates. Section B grooves take V-belts of that profile, and the five grooves allow the power to be distributed among several belts in parallel. The pulley is mounted on the shaft of the driven equipment or the motor, depending on how the drive is assembled.

Typical applications are fans, exhausters, compressors, centrifugal pumps, screens, belt conveyors and machines with belt drive. In all those cases the pulley works together with an electric motor and a smaller drive pulley, and the ratio between the two diameters defines the shaft's revolutions per minute. It is also used in equipment where an existing drive needs to be corrected or a worn pulley replaced.

To select the pulley properly, take into account the shaft diameter, the type of keyway, the number of grooves and the belt section the equipment already uses. Verify that the drive pulley and the driven pulley share the same section and that the center distance allows tensioning. During assembly, align the pulleys with a straightedge or a laser, check the parallelism of the grooves and tension the belts according to the belt manufacturer's manual.

If you need a nearby size, another diameter, another number of grooves or a pulley for a larger shaft diameter, send us the equipment data: pulley diameter, grooves, section, shaft diameter and type of keyway. With that, we look for the equivalent within our in-house manufacturing line or offer you the pulley made to measure. We can also check whether the drive accepts a pulley of another diameter without changing the rest of the assembly.
