Description
EMMAR POLEA 280 3B 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 3B and any equivalents.
The EMMAR 280 3B is a three-groove, section B pulley with a 280 mm outside diameter. It is manufactured in-house and is used in belt drives that need to transmit motion between parallel shafts with a stable speed ratio and enough capacity for multiple belts.
The designation POLEA 280 3B tells you the main data: 280 mm outside diameter, 3 grooves, section B. Section B is a classic V-belt profile, and the three grooves let you run up to three belts side by side on the same pulley. Because the pulley is made in-house, machining and dimensional checks are handled at the factory.
You will find this pulley in drives for machine tools, compressors, fans, centrifugal pumps, conveyors and process equipment. In each case, the pulley transfers torque from a motor to a driven shaft while keeping the speed ratio steady. With three grooves, it can carry more power than a single-groove pulley of the same diameter and gives you some margin if one belt wears.
When selecting or replacing this pulley, check the shaft diameter, keyway type and fastening method. Confirm that the belt section is B and that the number of grooves matches the number of belts you plan to use. Proper alignment between the driving and driven pulleys helps prevent uneven wear and vibration. Before startup, also inspect belt tension and the condition of the grooves.
If you need an equivalent, send the part number POLEA 280 3B or the original pulley data: diameter, number of grooves, section and shaft diameter. With that, we can identify a suitable pulley from our manufacturing or evaluate a special size. We can also help you choose the right number of grooves and section for your drive.

Frequently asked questions
- What does section B and 3 grooves mean?
- Section B is the V-belt profile the pulley accepts. The 3 grooves are the channels where the belts sit, so you can mount up to three section B belts in parallel on the same pulley.
- How do I know if this pulley replaces the one I have?
- Compare the outside diameter, number of grooves, belt section and shaft diameter with keyway. If those match, it is likely compatible. If not, send us the dimensions and we will look for an equivalent.
- Can I request a different number of grooves or diameter?
- Yes. Since it is in-house manufacturing, we can evaluate variants of diameter, number of grooves and section. Send the part number or the dimensions you need by WhatsApp and we will quote the alternative.
