The POLEA 320 5C is a V-belt drive pulley built to section C, measuring 320 mm in diameter and carrying 5 grooves. It transfers torque from a motor to a machine shaft and sets the speed relationship between the two sides of the drive through the ratio of pulley diameters. EMMAR produces this pulley, with dimensional checks performed during manufacturing, so it fits into power transmission arrangements where several belts work side by side to share the load.
Read the designation in three parts: 320 is the diameter in millimeters, 5 is the number of grooves, and C is the belt section. Section C covers wide-profile V-belts, and five grooves mean five belts of that same profile can run on one pulley. Diameter 320 mm is what determines the drive ratio once this pulley is paired with another in the system. Grooves are machined and concentricity is verified during production so the belts track evenly.
Typical installations include compressors, fans, pumps, mills, conveyors, process equipment, mixers, screens and machine tools. Five grooves suit medium and high power duties where one belt would not carry the drive: spreading the work across five belts lowers the load seen by each belt and by the shaft bearings. This makes the pulley a common choice where equipment runs continuously and reliability matters.
Before mounting, confirm the shaft size and fit and check that the key seats without play. Bring the driving and driven pulleys into line using a straightedge or laser, since misalignment damages both grooves and belts. Set belt tension following the belt manufacturer's manual, avoiding both over-tightening and slack. Keep the five grooves clean and free of burrs. For high-speed operation, balancing is recommended. Our team can help with selection based on your equipment's power and RPM.
Other groove counts, diameters and sections can be produced to order. To request an equivalent, provide the original pulley's part number, groove count, outside diameter, shaft diameter and the belt type in use. With those details we confirm the right part and issue the quote.
EMMAR also supplies belts, bearings, housings and other transmission components. For a quote on the 320 5C pulley or a variant, send the part number POLEA 320 5C by WhatsApp or email; we reply promptly and can suggest equivalents and help with selection.

Frequently asked questions
- What does section C mean on this pulley?
- Section C is a V-belt profile wider than sections A or B, used where more power per belt is needed. This pulley has five section C grooves, so five belts of that profile can run in parallel.
- Can this pulley replace one from another brand?
- If diameter, groove count, section and shaft diameter all match, yes. Send the original pulley's data and we will confirm the equivalence. Because EMMAR manufactures these pulleys, a custom version is also possible when nothing standard fits.
- How do I request a quote?
- Send the part number POLEA 320 5C by WhatsApp or email with the quantity you need. If you are unsure about shaft size or section, include a photo of the old pulley or the belt data. We will reply with the quote and technical information.
