The 650 4B pulley is a power transmission pulley of in-house manufacturing, EMMAR Accesorios Industriales brand, designed to mount on shafts and transmit motion via section B V-belts. With a 650 mm diameter and 4 grooves, it allows organizing the drive of equipment that requires several belt lines in parallel. It is used in industrial installations where a robust, balanced wheel with machined grooves is needed for stable operation.

This item is a pulley with a 650 mm diameter, 4 grooves and section B. The designation POLEA 650 4B summarizes those three variables: the outer diameter of the wheel, the number of grooves and the belt profile it houses. Section B corresponds to a type of V-belt widely used in medium-power industrial drives. The grooves are machined so that the belt seats evenly and contact is distributed along the entire arc.

Typical applications of a pulley of this size and number of grooves include industrial fans, compressors, centrifugal pumps, mills, mixers and transmission lines with electric motors. It is also used in lifting equipment and in continuous process machines where speed must be multiplied or reduced with a stable ratio. Having 4 grooves, it allows mounting several belts to distribute the load and sustain the drive if one line goes out of service.

To select and mount this pulley, take into account the shaft diameter, the type of keyway and the fastening system you will use. Verify that the belt section matches the groove and that the number of grooves is adequate for the power to be transmitted. Alignment between driving and driven pulleys is key to avoid uneven wear of belts and grooves. It is advisable to check balancing and concentricity before starting the equipment.

If you need a pulley with a different number of grooves, another diameter or a different section, we can evaluate a nearby size or an equivalent. To do so, send us the code POLEA 650 4B or the data of the original pulley via WhatsApp, along with the belt section and the number of grooves your equipment requires. With that information, the technical team at MR Accesorios Industriales can guide you on the option that best suits your drive.

As in-house manufacturing, EMMAR brand, this pulley is produced under machining control and construction variants can be inquired about according to the application.
