When you need to transmit rotation between shafts and adjust speed through diameter ratio, a V-belt pulley is often the answer. The EMMAR 320 mm 3-groove B-section pulley, part POLEA 320 3B, is made for that job. It is manufactured in-house, so you can count on a component built to the technical requirements of your drive system.
This pulley has a 320 mm diameter, three grooves, and a B-section profile. The B section matches a standard V-belt size, so belt fit is predictable. With three grooves, you can run up to three belts side by side, which raises the power the drive can handle. At 320 mm, it is a medium-to-large pulley, useful when you need a specific speed ratio between the motor and the driven machine.
You will find pulleys like this on compressors, centrifugal pumps, fans, mills, conveyors, and other process equipment. They take power from an electric motor or turbine and pass it to the next machine. By changing the diameter ratio between pulleys, you change the output speed. Using multiple belts also spreads the load and reduces the chance of slipping.
Before mounting, check that the shaft diameter and length match the pulley bore and that the fastening method (keyway, set screw, etc.) is correct. Align the pulleys carefully; misalignment causes uneven belt wear and vibration. When selecting, consider the power to transmit, the rotation speed, and the belt type. The number of grooves and the section must match the other pulleys in the system.
If you need a different size, groove count, or section, we can manufacture it or source an equivalent. Send the original part number, a photo, or a sketch with outside diameter, bore diameter, overall width, number of grooves, and section. With that, we can identify the part or develop a custom solution. Our team can also advise you technically on pulley selection.

Frequently asked questions
- What does B section mean for this pulley?
- B section is a standardized V-belt profile. It defines the belt dimensions that fit the pulley grooves. Using the correct section ensures proper fit and efficient transmission.
- Can I run this pulley with fewer than three belts?
- Yes, you can use fewer belts, but the power transmission capacity drops proportionally. If the system needs to transmit a specific power, use the number of belts the pulley was designed for.
- How do I request a pulley with a different size?
- Send the diameter, number of grooves, section, and bore diameter you need. With that information, we can manufacture it or find an equivalent. More details mean a faster response.
