The EMMAR 800 3B is a V-belt pulley with an 800 mm diameter, three grooves and a section B profile. It transfers power between parallel shafts in equipment that runs at moderate speed but needs high torque. Because EMMAR manufactures this pulley in-house, the machining and balancing are controlled for steady operation.
The 800 mm diameter sets the drive ratio when paired with a smaller drive pulley. Three grooves let you run up to three B-section V-belts side by side, which spreads the load across the belts. Section B is a specific V-belt profile and cannot be mixed with sections A, C or D. The pulley is built for shafts turning at moderate speeds while transmitting high power, and it resists alternating bending fatigue well.
You will find this pulley in mills, mixers, conveyor belts, screw compressors, high-flow centrifugal pumps and industrial fans. It also appears in woodworking machines, crushers and continuous process equipment. In each case the job is to move motion from an electric motor or gearbox to the working shaft, and you can adjust speed by changing the diameter of the drive pulley.
Selection comes down to four things: pitch diameter, number of grooves, belt section and shaft keyway. Confirm that the shaft diameter matches the pulley bore and that the keyway is correct. During installation, keep the shaft clean and free of burrs, and use a puller or press—never strike the pulley. Once it is mounted, check pulley alignment with a straightedge or laser to prevent uneven belt wear.
If you need a different number of grooves, another diameter or a different section, EMMAR can manufacture it. We can also quote an equivalent pulley from another brand when you provide the shaft measurements, keyway and belt section. Send the part number MR-POLEA-B3-800 or the designation POLEA 800 3B through WhatsApp or email, and we will reply with the alternative that best fits your equipment.

Frequently asked questions
- What does section B mean for this pulley?
- Section B is a standardized V-belt profile with its own width and height. It is not interchangeable with sections A, C or D. This pulley has three grooves, so you can mount up to three section B belts.
- Can I order a pulley with a different diameter or number of grooves?
- Yes. Since EMMAR manufactures these pulleys in-house, we can make them with different measurements, groove counts and sections. Send the shaft measurements, keyway and belt section via WhatsApp, and we will quote you.
- How do I check if this pulley fits my equipment?
- Look at the shaft diameter, keyway, belt section and number of grooves. If you send us those details on WhatsApp, we will help you confirm whether the 800 3B pulley is right or if another size works better.
