The 650 4B pulley is a power transmission pulley, in-house manufactured, EMMAR Accesorios Industriales brand, designed to be mounted on shafts and transmit motion through section B V-belts. With a 650 mm diameter and 4 grooves, it allows the drive of equipment requiring several belt lines in parallel to be arranged. 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 outside 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 increased or reduced with a stable ratio. Because it has 4 grooves, it allows several belts to be mounted to share the load and keep the drive running if one line is 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. Check that the belt section matches the groove and that the number of grooves is suitable for the power to be transmitted. Alignment between the driving and driven pulleys is key to avoiding uneven wear of belts and grooves. Balancing and concentricity should be checked before starting up the equipment.

If you need a pulley with another number of grooves, another diameter or a different section, we can evaluate an equivalent. To do so, send us the part number POLEA 650 4B or the data of the original pulley by 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 variants can be inquired about according to the application. If your equipment runs with a similar pulley, write to us on WhatsApp and send us the part number or the main dimensions. We will reply with the corresponding reference and the technical data so you can evaluate it.
