When you need to transmit power from a shaft using B-section V-belts, the EMMAR 210 3B pulley gives you a 210 mm diameter and three grooves. That combination lets you run multiple belts side by side, which increases torque capacity and provides a backup if one belt fails. You will find this pulley in mills, mixers, compressors, and other continuous-process machines where consistent speed and power are critical.

The part is designated POLEA 210 3B. Its key specs are straightforward: 210 mm diameter, 3 grooves, and section B. Section B is a standard V-belt profile, and the three grooves accept three belts of that same profile to share the load. The 210 mm diameter sets the drive ratio when paired with another pulley. This is an in-house manufactured EMMAR brand component built for tough industrial duty.

Typical uses for a 210 mm, 3-groove B-section pulley include belt drives on mills, mixers, compressors, centrifugal pumps, high-flow fans, and machine tools. You will also see it on conveying equipment and production lines that must hold steady speed despite load changes. Because it has three grooves, it often appears in systems where redundancy matters: if one belt breaks, the remaining two keep transmitting power until you can replace it.

For selection and mounting, check the shaft diameter, keyway type, and fastening method (set screw, cone, or bushing). Confirm the belt section is B and that the groove count matches the power you need to transmit. Proper alignment between pulleys is crucial to prevent uneven belt wear and vibration. If you use a taper bushing, clean the mating surfaces thoroughly and apply the tightening torque specified by the bushing maker.

If you need a different size, groove count, or section, we can manufacture it. MR Industrial Accessories makes custom pulleys and offers other power transmission options. To request an equivalent, send us the existing part number, a photo, or a sketch with the main dimensions: outer diameter, shaft diameter, number of grooves, and section. We will quote the best match from our standard or custom line.
