The EMMAR 120 3A pulley is a V-belt drive component with a 120 mm diameter, three grooves, and section A profile. It transfers motion between parallel shafts in industrial machinery, distributing power across multiple belts. Manufactured in-house by EMMAR, the bore and keyway can be machined to match your specific shaft requirements.
The part number POLEA 120 3A indicates the key dimensions: 120 mm diameter, three grooves, and section A. The grooves are shaped for section A V-belts, so the belt contacts the flanks rather than the bottom. This pulley is manufactured in-house under the EMMAR brand and is designed to mount on a shaft with a keyway.
Common uses include compressors, fans, pumps, mixers, conveyor drives, and other plant equipment with belt transmissions. When a single belt cannot handle the required power, multiple belts run in parallel—hence the three grooves. The diameter ratio between driving and driven pulleys also sets the speed of the driven shaft relative to the motor.
When selecting and installing this pulley, consider shaft diameter and keyway, center distance, desired transmission ratio, and power to be transmitted. Confirm that the belt is section A and that the number of grooves matches the number of belts in the drive. Proper alignment between pulleys prevents belt mis-tracking and uneven wear. If your shaft diameter differs, the bore can be machined to size.
For a different number of grooves, another diameter, or a different section, send us the specifications and we will check the in-house manufacturing line. We can also review an equivalent if the application calls for another configuration. The more details you provide—shaft diameter, keyway, belt section, and number of grooves—the faster we can confirm the correct part.

Frequently asked questions
- What does section A mean for this pulley?
- Section A refers to the V-belt profile that the groove accommodates. It determines the groove width and depth so the belt rests on the flanks. It is not interchangeable with other sections like B or C because the groove dimensions differ.
- Can I order this pulley with a different shaft diameter?
- Yes. Because it is in-house manufacturing, the bore and keyway are machined to match your machine's shaft. Provide the shaft diameter, keyway dimensions, and number of grooves, and we will confirm the part.
- How do I request a quote for this pulley?
- Send the part number POLEA 120 3A by WhatsApp along with the quantity and shaft dimensions. With that information we will prepare your quote. If you need a variant, specify the diameter, section, or number of grooves you require.
