The 290 4C pulley is a section C V-belt drive pulley, 290 mm in diameter with 4 grooves. It is used to drive parallel shafts in industrial equipment, where power must be transmitted with a good speed ratio and low maintenance. Because it is in-house manufactured, EMMAR brand, the machining can be adapted to the equipment's needs. It is mounted with a keyway on the shaft and aligned with the drive pulley to avoid uneven belt wear.

This item is a pulley 290 mm in diameter, 4 grooves, section C, according to its designation POLEA 290 4C. Section C corresponds to V-belts with a wide profile, and the 4 grooves allow a set of four belts to be fitted in parallel. The 290 mm diameter defines the transmission ratio when combined with the drive pulley. Machining includes the keyway and turned grooves so that the belts seat evenly along their full length.

It is used in machine and equipment drives where the shaft rotates at medium speeds and power is distributed among several grooves. It appears in compressors, centrifugal pumps, fans, mills, conveyor belts and machine tools. Also in continuous process equipment, where a multi-groove pulley allows operation to continue if one belt breaks, until replacement can be scheduled. In plants with many drives, section C is common due to its load capacity and wide range of available belts.

To mount it, check that the shaft diameter and keyway match the pulley machining. Align the drive and driven pulleys with a straightedge or laser: angular or parallel misalignment shortens belt life and generates vibration. Tension the belts according to the equipment manual and check tension after the first hours of operation. If the pulley runs with four grooves, replace the belts as a set so that all take load equally.

If you need a pulley of a different size, with more or fewer grooves or for another section, it can be manufactured to order. To request an equivalent or a nearby size, send the code POLEA 290 4C or the equipment data: diameter, number of grooves, belt section and shaft diameter with keyway. With that data the machining is defined and the part is confirmed before manufacturing.

MR Accesorios Industriales manufactures this pulley in its factory and sells it together with belts, bearings and housings to build the complete drive. If you have questions about the pulley that corresponds to your equipment, send the code or a photo of the old pulley via WhatsApp and we will help you identify it. We can also review the complete drive to suggest the right combination of pulleys and belts.
