Description
EMMAR POLEA 380 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 380 7B and any equivalents.
The EMMAR POLEA 380 7B is a V-belt pulley that mounts on a shaft to transfer torque from a motor to driven equipment. With a 380 mm diameter and seven grooves for section B belts, it suits drives where the load is shared across multiple belts, which helps reduce slip and distribute wear. MR manufactures this pulley.
The code POLEA 380 7B packs the key selection data: the outside diameter (380 mm), the number of grooves (7) and the belt profile (section B). Section B is a classical V-belt profile common in industrial drives. Because MR produces this pulley, the groove geometry is controlled so the belts seat correctly and line up with the rest of the drive.
You will find a 7-groove section B pulley in equipment that transmits moderate to high power through several belts running in parallel. Examples include industrial fans, centrifugal pumps, screw compressors, vibrating screens, bucket elevators and machine tools. It is also a practical choice when replacing a worn pulley or when you need to change the driven speed without touching the motor.
Before mounting, confirm the shaft diameter and keyway match the pulley bore, and that the pulley is aligned with the drive pulley. Use as many belts as there are grooves; running fewer belts than grooves reduces the power the drive can transmit. Check belt tension and inspect the grooves for uneven wear, which can cause vibration and shorten belt life. If you do not have the data sheet, ask us for the mounting information.
For an equivalent pulley, send the part number POLEA 380 7B or the diameter and groove count you need. We can also review options in other sections or with a different number of grooves. As a manufacturer of pulleys and other transmission components, MR can help you match the right option to your equipment. Reach us on WhatsApp or by email for a quote.

Frequently asked questions
- What does POLEA 380 7B mean?
- It identifies a pulley with a 380 mm diameter, 7 grooves and section B for classical V-belts. If your pulley has a different diameter or groove count, send us those details and we will look for an equivalent.
- What type of belt does it use?
- Section B V-belts. Using the correct section ensures the belt seats properly in the groove and avoids slip and premature wear. If you are unsure of the section, contact us with the belt part number.
- How do I request a pulley with another size?
- Send the diameter, number of grooves and section you need via WhatsApp or email. A photo or the part number of the old pulley also helps. With that information we can quote a custom manufacturing.
