The 320 5C pulley is a V-belt drive pulley, section C, with a 320 mm diameter and 5 grooves. It is used to drive machine shafts from a motor, transmitting torque and regulating speed according to the diameter ratio between pulleys. It is manufactured by EMMAR in Argentina, with in-house dimensional control, and integrates into power transmission systems that require several belts in parallel to distribute the load.

This item is a pulley with a 320 mm diameter, 5 grooves and section C, per the designation POLEA 320 5C. Section C corresponds to wide-profile V-belts, and the 5 grooves allow five identical belts to be mounted on the same pulley. The 320 mm diameter defines the drive ratio when combined with another pulley in the system. The part is manufactured at MR with machined grooves and concentricity verification so the belts run aligned.

It is used in industrial machine drives: compressors, fans, pumps, mills, conveyor belts and process equipment. It also appears in the drive of mixers, screens and machine tools. With 5 grooves, it is suitable for medium and high power where a single belt is not enough: the load is distributed among the five belts, which reduces the stress on each one and on the shaft bearings. It is common in installations that require reliability and continuous operation.

To mount this pulley, verify that the shaft has the correct size and fit, and that the key fits without play. Align the driving and driven pulleys with a straightedge or laser: misalignment wears the grooves and the belts. Tension the belts according to the belt manufacturer's manual, without over-tightening or leaving them loose. Check that the 5 grooves are clean and free of burrs. If the pulley will rotate at high speed, it should be balanced. At MR we can advise you on selection according to your equipment's power and RPM.

If you need a pulley with a different number of grooves, another diameter or a different section, it can be custom manufactured. We can also evaluate a nearby size within the MR pulley line. To request an equivalent, send us the original pulley's part number, the number of grooves, the outside diameter, the shaft diameter and the type of belt you use. With that data we confirm the correct part and send you the quote.

MR Accesorios Industriales manufactures this pulley in the country and sells it together with belts, bearings, housings and other transmission components.
