Description
EMMAR POLEA 380 3A 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 3A and any equivalents.
The EMMAR 380 3A is a V-belt pulley with a 380 mm outside diameter, three grooves and section A. It is manufactured in-house by MR, so the bore and keyway can be machined to match your equipment shaft. This pulley suits fans, compressors, pumps, mills and conveyors that run on A-profile belts and need a steady transmission ratio with reliable belt grip.
The part number POLEA 380 3A covers this specific size and groove configuration. The grooves are cut so each V-belt sits evenly and does not slip. Depending on the case, the body is cast iron or steel, and balancing is controlled to limit vibration at normal operating speeds. The pulley is supplied with the bore and keyway defined according to the shaft it will mount on.
Typical uses include industrial fans, screw compressors, centrifugal pumps, mills, mixers and conveyors, as well as agricultural machinery and process lines where speed must be adjusted between the motor and the driven machine. With three grooves, the load is shared across several belts, which helps extend the service life of the assembly and provides margin if one belt fails.
When selecting the pulley, check the shaft diameter, keyway type, center distance and the transmission ratio you need. Confirm that the belt section matches section A and that three grooves are enough for the power being transmitted. During mounting, keep the shaft clean and free of burrs, and align the pulley with the drive pulley to avoid uneven belt wear.
If you need an equivalent pulley, send the part number POLEA 380 3A or the equipment data: diameter, grooves, section and shaft diameter. We will indicate the in-house manufactured pulley that fits or machine it to measure. We can also quote the complete assembly with belts and bushings if needed. To request a quote, write to us on WhatsApp and include the part number POLEA 380 3A.
MR supplies bearings, mounted units and housings, power transmission parts, seals, lubrication and maintenance tools to customers across the United States and in several Latin American countries. The team replies promptly and can suggest equivalents or help you choose the right component.

Frequently asked questions
- What does it mean that this pulley is in-house manufactured by EMMAR?
- It means MR makes it in its own factory rather than buying it from a third party. That allows the machining, bore and keyway to be adjusted to the equipment's requirements, with technical support on the part.
- Can I order this pulley with a different shaft diameter?
- Yes. Because it is in-house manufactured, the bore and keyway can be machined to the shaft size. Provide the diameter, shaft length and keyway type when requesting a quote.
- How do I confirm that section A is the right one?
- Section A refers to a V-belt profile. Check the width and height of the belt you use or the code stamped on the old belt. If in doubt, send us a photo or the measurement and we will confirm.
