When a drive needs several B-section belts working side by side, the EMMAR 210 6B pulley is built for that job. It measures 210 mm across and carries six grooves, so power moves from the driving shaft to the driven shaft through a wide belt contact area. Fans, pumps, compressors and conveyors are common homes for this size, especially where the load is moderate to heavy and shaft speeds stay high. Because EMMAR produces these pulleys in-house, diameter and balance are held to a consistent spec.
Reading the code is straightforward: 210 is the outside diameter in millimeters, 6 is the groove count, and B is the belt cross-section the pulley accepts. The pulley mounts on a cylindrical shaft, and the bore is set when you order. In-house machining keeps the groove profile and the running surface concentric, which helps the pulley line up with its counterpart on the driven side.
Six parallel B-section belts are the reason this pulley shows up on centrifugal fans, water pumps, screw compressors, vibrating screens, belt conveyors and machine tools. Refrigeration units and process lines that need a steady transmission ratio over long running periods also use it. The multi-groove layout spreads the load across all six belts instead of concentrating it on one.
Before ordering, confirm three things: the shaft diameter that will set the bore, the belt section (B), and the groove count so it matches the other pulleys in the drive. Alignment matters, so check the two pulleys with a straightedge or laser before tensioning. Set belt tension to the belt maker's recommendation. If the shaft is keyed, the pulley needs a matching keyway to stop it from turning on the shaft.
Need a different groove count, a different diameter or a bore for another shaft? Since EMMAR manufactures these pulleys, those changes can be made. Send the part number 210 6B, or just the diameter and section you require, and the team will quote the closest option. They can also help you work out how many belts to run and the smallest pulley diameter for the power involved.

Frequently asked questions
- What does the 210 6B designation tell me?
- It packs three specs into one code: 210 mm outside diameter, six grooves, and a section B belt profile. The pulley is an EMMAR V-belt drive component that mounts on a shaft and transfers power to a second pulley through the belts.
- Which belts fit this pulley?
- Section B V-belts. Keep every belt in the drive on the same section and length so the load is shared evenly and no single groove carries more than its share.
- Can the groove count, diameter or bore be changed?
- Yes. EMMAR manufactures these pulleys, so the groove count, outside diameter and shaft bore can be adapted. Send the details by WhatsApp or email and the team will quote the custom version.
