The 550 2B pulley is a V-belt drive pulley with section B, 550 mm diameter and two grooves. It is used to transmit power between parallel shafts in industrial equipment, where a stable transmission ratio and good belt grip are required. MR Accesorios Industriales manufactures it locally, with dimensional control over the diameter and grooves so it fits the shaft without forced adjustments and the belts seat evenly.

This item is a pulley with a 550 mm diameter, 2 grooves and section B. The designation POLEA 550 2B summarizes those three data points: the outer diameter, the number of grooves and the belt profile it accepts. Section B corresponds to classic-type V-belts, widely used in medium-power industrial drives. Because it is in-house manufactured, EMMAR brand, the machining of the groove and the balancing are controlled so the pulley rotates without vibration at the usual working speeds.

It is used in machines and equipment that need to reduce or increase speed between a motor and a driven shaft: compressors, fans, centrifugal pumps, conveyor belts, mixers and mills, among others. It also appears in factory drives and process equipment where a fixed transmission ratio must be maintained with section B belts. Having two grooves allows mounting two belts in parallel to distribute the load and keep the service running if one of them fails.

To select it, take into account the shaft diameter, the type of keyway, the number of grooves and the belt section. Verify that the driving and driven pulleys use the same section and that the center distance allows correct tensioning. The 550 mm diameter conditions the tangential speed: the higher the shaft speed, the higher the peripheral speed, so it is advisable to check that the pulley and belts are balanced and aligned. Alignment between pulleys and parallelism of the shafts are key for the belts to last and not come out of the groove.

If you need a different size or an equivalent pulley, send us the part number, the diameter, the number of grooves and the belt section. It also helps if you send us the shaft diameter and the type of keyway. With that data we look for a pulley in the same category or a nearby size within the section B line. If the item is not listed on the site, we can still manufacture it or source a compatible alternative.
