Description
EMMAR POLEA 280 4B 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 280 4B and any equivalents.
The POLEA 280 4B is a V-belt drive pulley with a 280 mm diameter, four grooves, and a section B profile. It is manufactured in-house by EMMAR and is used to transmit motion from a motor to a driven shaft, adjusting speed based on the pulley diameter combination. This four-groove design lets you run up to four B-section belts in parallel, making it suitable for medium-power drives.
The part number POLEA 280 4B encodes the key specifications: 280 mm outside diameter, four grooves, and section B. Section B corresponds to V-belts with a B profile. The pulley mounts on the equipment shaft and, with the belts, transfers power from the motor. Because it has four grooves, the load is spread across up to four belts, which allows it to handle more power than a single-groove pulley of the same diameter.
Typical uses include fans, centrifugal pumps, compressors, conveyors, mixers, and machine tools in industrial plants, as well as agricultural implements and workshop drives. Section B pulleys are common where a balance between load capacity and moderate peripheral speed is needed. For equipment running many hours per day, check alignment and belt tension regularly.
When selecting a pulley, consider pitch diameter, number of grooves, and belt section. Section B accepts B-profile belts, and the groove count determines how many belts can be mounted in parallel. Confirm that the pulley diameter matches the shaft speed and the driving pulley diameter so the drive is not overloaded. During installation, verify the keyway and shaft fit, and align the pulleys to prevent uneven wear.
If you need a different number of grooves, another diameter, or a different section, an equivalent can be requested. Send the part number POLEA 280 4B or the original pulley data: diameter, grooves, section, and shaft type. Custom pulleys can also be quoted if mounting dimensions are provided.
To request a quote or ask about a variant, send the part number POLEA 280 4B via WhatsApp or email. MR Industrial Accessories LLC manufactures pulleys and other transmission components, and can help you choose a pulley that works with your existing belts and shaft.

- Which belts fit this pulley?
- It uses V-belts of section B, which matches the pulley grooves. You can mount up to four belts, one per groove.
- Can I get a pulley with a different groove count or diameter?
- Yes. Since it is in-house manufacturing under the EMMAR brand, pulleys with other sizes, groove counts, or sections can be quoted. Send the original pulley data or part number and we will provide the right option.
