Description
EMMAR POLEA 340 3B 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 340 3B and any equivalents.
The 340 3B pulley from EMMAR is a V-belt drive component with a 340 mm diameter, 3 grooves, and section B. It transfers power between parallel shafts in equipment that uses section B belts, such as fans, compressors, pumps, and conveyors. Because EMMAR manufactures this pulley in-house, you can also request variations in diameter and groove count within the same section.
The part number POLEA 340 3B encodes the key specifications: 340 mm outside diameter, 3 grooves, and section B. Section B refers to the V-belt profile, a common choice for intermediate-power industrial drives. The grooves are machined to seat the belt evenly, ensuring contact across the full arc.
This pulley is found in belt drives that adjust speed between a motor and driven machine. Typical applications include centrifugal fans, screw compressors, centrifugal pumps, conveyor belts, mixers, and process equipment. It also appears in machine tools and transmission systems where vibration absorption and overload protection are needed—advantages a belt drive offers over a rigid coupling.
When selecting a pulley, consider the power to be transmitted, the rpm of both shafts, and the number of belts. These factors determine the pitch diameter and groove count. During installation, verify pulley alignment, belt tension, and that keys and set screws are tight. Even slight misalignment can reduce belt life and stress shaft bearings.
For a different size or additional grooves, send the part number POLEA 340 3B or the details of the pulley you are replacing. With diameter, section, and groove count, we can check equivalents within our in-house manufacturing line. If you have the original pulley, also provide the bore diameter and shaft fixing type to confirm fit without modification.

Frequently asked questions
- What does section B mean?
- Section B defines the V-belt profile that the groove accepts. It is widely used in intermediate-power industrial drives. The belt and pulley must share the same section for proper operation.
- Can I order a different diameter or more grooves?
- Yes. Since EMMAR manufactures this pulley in-house, you can inquire about diameter and groove-count variants within section B. Send us the equipment data and we will confirm which alternative fits.
- How do I know if it replaces my current pulley?
- Compare diameter, section, and number of grooves. Also check the bore diameter and shaft fixing type. With that data we verify the equivalence before quoting.
