The POLEA 320 3C is a three-groove pulley built by EMMAR for section C belts, with a 320 mm diameter. Because it comes from our own machining, the bore and keyway can be finished to match the shaft it will sit on. Maintenance teams use it both when assembling new drives and when swapping out a worn pulley where the existing ratio has to stay the same.
Read the code from left to right and you have the whole specification: 320 is the diameter in millimeters, 3 is the number of grooves, and C is the belt section. Section C belts carry a taller cross-section than A or B, which is why this pulley turns up on drives that move heavier loads or where there is not much room between shafts. Spreading the work across three belts keeps the pull on each one lower.
You will find this size on screw compressors, centrifugal fans, mills, mixers and conveyors, and also on pumps and farm equipment where a steady drive with little vibration matters. Running multiple belts also means the drive tolerates uneven wear better and can keep turning if one belt gives out, though changing the whole set at once is the better habit.
When you specify the pulley, confirm the pitch diameter, groove count and belt section, then check the bore and keyway against the shaft and make sure the center distance leaves room to tension the belts. Line up the drive and driven pulleys before tightening anything, since misalignment is what usually shortens belt life. On shafts that see axial load, a taper bushing or similar fixing helps hold concentricity.
Need another diameter or a different groove count? Send the part number you are running now along with the belt section, diameter and number of grooves, and we will look at what matches. Variants in EMMAR in-house manufacturing can also be reviewed. The more detail you provide, the quicker we can come back with something that fits your equipment.
For a quote on the POLEA 320 3C or any other drive pulley, message us on WhatsApp or by email with the part number. If you are unsure about the section or the groove count, a photo of the old pulley or the shaft dimensions is usually enough for us to identify the replacement.

Frequently asked questions
- What does section C mean on this pulley?
- It tells you which belt profile fits the grooves. A section C belt is taller and wider than an A or B belt and carries more power. This pulley has three grooves cut for that profile, so three belts can run side by side.
- Can I run it with fewer than three belts?
- You can, but the drive will transmit less power. Using fewer belts than the pulley has grooves lowers the maximum load the assembly can handle, so running the full set is the better choice.
- How do I ask for an equivalent pulley?
- Send the part number of your current pulley, the belt section, the diameter and the groove count by WhatsApp or email. With those details we can quote an equivalent, and a drawing or photo helps even more.
