For drives that need a single B-section V-belt, the EMMAR pulley with a 320 mm diameter and one groove is a straightforward solution. It mounts on a shaft and transfers motion to or from a belt, and it is manufactured in-house, so dimensional accuracy and balance are checked before it ships.
The part number POLEA 320 1B tells you the essentials: a 320 mm diameter, one groove, and a section B profile. That single groove means one belt runs in it, which keeps mounting and alignment simple on shafts where you do not need to multiply power. Section B is an intermediate V-belt profile used in medium-power drives, so it covers many industrial applications without requiring an oversized pulley.
You will find this size in industrial fans, compressors, centrifugal pumps, conveyor drives, and machine tools. It also shows up in process equipment, mixers, and extraction systems. In every case, the pulley is one part of a drive assembly that includes the shaft, hub, and belt. The section B choice comes down to the power and speed your system runs at.
Before mounting, confirm the shaft diameter matches the hub bore and that the key fits without play. Align the driving and driven pulleys as closely as you can, because even a few degrees of misalignment will speed up wear on the belt and on the equipment bearings. Set belt tension according to the machine manufacturer's manual, neither loose nor overly tight. At higher speeds, check balancing before putting the pulley into service.
If your application calls for a different diameter or more grooves, we can manufacture it. Just send the outside diameter, number of grooves, belt section, and bore diameter with keyway. We can also quote an equivalent pulley if you provide the part number or key measurements. The goal is a direct replacement with no adaptation on your end.

Frequently asked questions
- What does section B mean for this pulley?
- Section B defines the V-belt profile that fits the groove. It is common in medium-power drives and is not interchangeable with other sections like A or C, because groove width and depth differ.
- Can I get this pulley with a different bore diameter?
- Yes. It is manufactured with the bore you specify. Provide the shaft diameter and keyway dimensions, and we will quote the pulley sized for your equipment.
- How can I tell if this pulley replaces the one I have?
- Check the outside diameter, number of grooves, and belt section. If they match, it is the same pulley. If unsure, send us the old part number or measurements and we will confirm equivalence before quoting.
