The EMMAR 320 4C is a V-belt drive pulley built to a 320 mm diameter with four grooves in section C. Drives that run parallel shafts in industrial machinery rely on this kind of sheave when they need a steady speed ratio and the capacity to carry a real load. Because MR produces this pulley in its own shop, the machining and balancing steps stay under direct control.

Read the code from left to right and the pulley tells you what it is. The 320 is the diameter in millimeters, the 4 is how many grooves are cut into the face, and the C is the belt profile the grooves are machined to accept. Section C belts belong to the medium and high power side of V-belt drives, so this sheave fits equipment where a single belt would not be enough.

Typical homes for a pulley like this include compressors, fans, pumps, conveyor drives, mixers and mills, plus test stands and process equipment where speed is adjusted by swapping sheaves. Four grooves let the drive spread its work across several belts instead of one, which lowers what each belt has to carry and makes the whole arrangement more dependable.

Before mounting, confirm the shaft diameter and keyway match, and that the pulley seats fully and stays centered. Alignment with the mating sheave matters just as much: parallel or angular offset wears out belts and bearings ahead of schedule. Set belt tension to whatever the equipment manual calls for. When you are matching a pulley already in service, work from diameter, groove count and section.

Need another size or a cross-reference? Send the complete part number, or the dimensions you have on hand: diameter, number of grooves, section and shaft diameter. That is enough for us to point you to the pulley that fits your drive, and we can look at building a custom one when the equipment calls for it.
