This EMMAR pulley, identified as POLEA 280 3C, is a three-groove, section C V-belt sheave with a 280 mm diameter. It is made in-house, so dimensions and machining are controlled throughout production. It works in belt drives where motion is transferred from one shaft to another, and it can serve as a replacement for a worn unit or as part of a new installation.
The code POLEA 280 3C tells you the main selection data: 280 mm diameter, three grooves, section C. Section C refers to the V-belt profile the grooves are cut to accept. With three grooves, the drive can run three belts side by side, which is how the load gets shared across the set. The diameter and groove count are what determine where this pulley fits in a drive.
Typical installations include mills, mixers, compressors, pumps, fans and conveyors, as well as agricultural equipment and production lines where shafts are set apart. The three-groove section C arrangement suits medium and high power requirements. Spreading the transmission across several belts lowers the chance of slip and helps keep the drive running steadily.
Before mounting, confirm that the shaft diameter matches the pulley bore and that the keyway lines up. Drive and driven pulleys need to be aligned so belts and bearings do not wear early. Set belt tension according to the belt maker's recommendation. When matching a pulley to an existing drive, work from the section, the number of grooves and the pitch diameter, which here is 280 mm.
If you need something other than this size, we can look at section C pulleys with a different diameter or groove count. Custom pulleys are also manufactured to order. To move quickly, send the outside or pitch diameter, the belt section, the number of grooves, and the shaft diameter with keyway dimensions. That information lets us point you to the right pulley.

Frequently asked questions
- What does section C mean on this pulley?
- Section C is a standard V-belt profile. The grooves on a section C pulley are cut to match that belt shape. This pulley has three such grooves, so three section C belts can be used together.
- Can this pulley replace one from another brand?
- It can, provided the key dimensions match: pitch diameter, number of grooves, section and shaft diameter with keyway. Send us the original pulley data and we will confirm whether this EMMAR pulley fits or which other size you need.
- How do I ask for a different number of grooves?
- Contact us on WhatsApp with the section, diameter and groove count you require. We produce section C pulleys in various diameters and groove numbers, and special sizes can be made on request.
