The 210 3B pulley is a power transmission component designed to mount on shafts and transmit motion through section B V-belts. With a 210 mm diameter and 3 grooves, it allows building drives with several belts in parallel, which translates into greater torque capacity and backup against failures. It is a key part in machines that need to maintain constant speed and power, such as mills, mixers, compressors and continuous process equipment.

This pulley is identified with the designation POLEA 210 3B. Its main attributes are: 210 mm size, 3 grooves and section B. Section B corresponds to a standardized V-belt profile, and the three grooves allow installing three belts of the same type to distribute the load. The 210 mm diameter defines the transmission ratio when combined with another pulley in the same system. It is an in-house manufactured part, EMMAR brand, designed for demanding industrial applications.

Typical applications of a 210 mm pulley with 3 section B grooves include belt drives in mills, mixers, compressors, centrifugal pumps, high-flow fans and machine tools. It is also used in conveying equipment and in production lines where stable speed must be maintained under load variations. Having three grooves, it is commonly seen in systems where redundancy is sought: if one belt fails, the other two continue transmitting power until it is replaced.

To select and mount this pulley, take into account the shaft diameter, the keyway type and the fastening system (set screw, cone or bushing). Verify that the belt section matches section B and that the number of grooves is the one needed for the power to be transmitted. Alignment between pulleys is essential to avoid irregular belt wear and vibrations. If the pulley is mounted with a taper bushing, make sure to clean the surfaces well and apply the tightening torque recommended by the bushing manufacturer.

If you need a pulley with another size, another number of grooves or a different section, we can manufacture it. MR Accesorios Industriales manufactures custom pulleys and also offers alternatives within the power transmission line. To request an equivalent or a nearby size, the most practical thing is to send us the current part number, a photo of the part or a sketch with the main dimensions: outer diameter, shaft diameter, number of grooves and section. With that data we quote the option that best suits you.
