EMMAR POLEA 340 7B 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 7B and any equivalents.
This EMMAR pulley, identified as POLEA 340 7B, is a 340 mm diameter, 7-groove, section B V-belt pulley. It is manufactured in-house and used to transmit power from a motor to one or more driven machines through parallel shafts.
The designation POLEA 340 7B tells you the key dimensions: a 340 mm outside diameter, 7 grooves, and a section B groove profile. The groove profile must match the belt section so the belts seat correctly and transfer power without slipping. With seven grooves, the pulley can carry up to seven section B belts, letting you spread the load across multiple belts or keep spares in place.
You will find this pulley in machine tools, compressors, centrifugal pumps, industrial fans, conveyor belts, and process equipment. In each case, it mounts on a shaft and connects to another pulley by section B belts. The seven grooves are useful when you need to transmit more power or want some redundancy if one belt breaks.
When selecting this pulley, check the shaft diameter, keyway type, and fastening method—taper bushing, set screw, or key. Confirm that the belt section matches the groove and that the number of grooves suits the power you need to transmit. Proper alignment between pulleys during mounting helps prevent premature wear on belts and bearings.
If you need a different diameter, groove count, or section, we can manufacture it. We can also evaluate an equivalent if you have a part number from another brand. Just send the complete data: diameter, number of grooves, section, and fastening type. We will quote the pulley that fits your application.
To order this pulley or a variant, send the part number POLEA 340 7B or the part you need to replace via WhatsApp or email. We will help you confirm the right solution. Our manufacturing covers pulleys, split plummer block housings, and ANSI chains, along with a broad line of industrial components.

Frequently asked questions
- What does section B mean for this pulley?
- Section B refers to the groove profile, which is designed for type B V-belts. Using the correct section ensures the belt fits properly and transmits power without slipping. Always match this designation when replacing the pulley or belts.
- Can I use fewer than 7 belts on this pulley?
- Yes, you can run fewer belts if your application allows it. However, to transmit the power the pulley was designed for, use the appropriate number of belts. If you need a different groove count, we can manufacture it to order.
- How do I request a custom pulley?
- Contact us via WhatsApp or email with the diameter, number of grooves, section, and fastening type you need. We will quote a custom pulley. If you have an original part number from another brand, we can also evaluate an equivalent.
