Description
EMMAR POLEA 380 3C belongs to pulleys, part of our Power transmission range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for POLEA 380 3C and any equivalents.
This EMMAR pulley, identified as POLEA 380 3C, is a V-belt drive component for mounting on a machine shaft. It measures 380 mm in outside diameter, carries three grooves and accepts section C belts. The three-groove layout lets the drive share its load across three belts running side by side, which keeps the drive running steadily. It suits equipment that handles heavy, continuous loads.
Reading the code is straightforward: the first figure gives the outside diameter (380 mm), the number in the middle is the groove count (3), and the letter at the end identifies the belt profile (section C). Section C covers wide-profile V-belts, so this pulley is chosen when a drive has to move power through a small number of belts. Because three belts share the work, no single belt carries the full load.
You will find pulleys of this size on mills, crushers, industrial mixers, screw compressors, high-flow centrifugal pumps and process fans, as well as on conveying and lifting equipment such as belt conveyors and bucket elevators. In every case the drive needs a stable speed ratio and low upkeep. Aligning the pulley with its shaft is what allows the three belts to pull evenly.
Before mounting, confirm the shaft diameter, the keyway type and the fastening method you plan to use. Make sure the belts you have are section C and that their number matches the three grooves. Check alignment between the driving and driven pulleys, since angular or parallel misalignment speeds up wear on both belts and grooves. Belt tension also matters: too loose and the belt slips, too tight and the equipment bearings take extra stress.
For an equivalent pulley, send the full part number along with the groove count and belt section you are running. With those details we can match a pulley from our own manufacturing or build one to your dimensions. We can also help you settle on the right shaft diameter and the hub or bushing type for your machine, so the rest of the drive stays as it is.
EMMAR produces this pulley and other power transmission parts, which we supply alongside belts, bearings and housings. To move ahead, send the part number POLEA 380 3C by WhatsApp or email and we will reply with a quote and the technical data you need to confirm the mounting.

Frequently asked questions
- What does POLEA 380 3C tell me about the pulley?
- It gives the 380 mm outside diameter, the groove count of 3, and the belt section C. That combination is meant for wide-profile V-belts, with three belts sharing the load.
- How do I ask for an equivalent or a different size?
- Send the part number, the number of grooves and the belt section you use. We will confirm whether an equivalent from our manufacturing fits or whether we need to make it to your dimensions.
- What should I check before mounting it?
- Confirm the shaft diameter, the keyway and the fastening system. Also check alignment with the driven pulley and set the belt tension correctly, since those factors determine how long the assembly lasts.
