The 550 1C pulley is a power transmission pulley of in-house manufacturing, EMMAR Accesorios Industriales brand. It is designed to be mounted on shafts and to take a section C V-belt, transmitting motion between equipment in a simple and robust way. Its 550 mm diameter and single groove make it suitable for applications requiring a specific transmission ratio and good belt wrap.

This item is a pulley of 550 mm diameter, with 1 groove and section C. The designation POLEA 550 1C summarizes those three variables: the pulley's outer diameter, the number of grooves and the belt section it accepts. Section C corresponds to a medium-size V-belt profile, common in medium and high power industrial drives. As it is of in-house manufacturing, EMMAR brand, variants within the same section can be requested.

Section C pulleys with a single groove are used in equipment where motion must be transmitted from a motor to a machine shaft: fans, centrifugal pumps, compressors, conveyor belts and mixers, among others. They also appear in agricultural machinery and in process equipment working at moderate speeds and variable loads. Choosing a pulley of 550 mm diameter usually responds to the need to adjust the final speed of the driven shaft.

To correctly select this pulley, take into account the diameter of the shaft where it is mounted, the type of keyway and the fastening system (set screw, cone or bushing). Verify that the belt is section C and that the number of grooves matches the number of belts on the equipment. Alignment between pulleys and belt tension are key to avoiding premature wear. If you need help defining the right pulley, send us your machine data.

If the part number POLEA 550 1C does not exactly match what you need, we can look for a nearby size or an equivalent within the same section C. To do so, send us the diameter, the number of grooves and the type of fastening your shaft requires. We can also evaluate a pulley of another diameter or with more grooves if space allows. The idea is for the pulley to fit your equipment without unnecessary modifications.
