The 340 3B pulley is a V-belt drive pulley, manufactured by EMMAR Accesorios Industriales. It has a 340 mm diameter, 3 grooves and section B. It is used to transmit power between parallel shafts in equipment that runs with belts of that section, such as fans, compressors, pumps and conveyors. Because it is in-house manufactured, you can inquire about diameter and groove-count variants within the same section.

This item is a pulley with a 340 mm diameter, 3 grooves and section B. The designation POLEA 340 3B summarizes those three variables: the outside diameter, the number of grooves and the belt section it takes. Section B corresponds to section B V-belts, widely used in intermediate-power industrial drives. The grooves are machined so that the belt seats evenly and contact is spread along the entire arc.

It is used in belt drives where speed must be reduced or increased between a motor and a machine. It appears in centrifugal fans, screw compressors, centrifugal pumps, conveyor belts, mixers and process equipment. Also in machine tools and in transmission systems where the aim is to absorb vibration and protect the motor against overloads, something a belt handles better than a rigid coupling.

To select the pulley, start from the power to be transmitted, the rpm of the drive shaft and of the driven shaft, and the number of belts the assembly will carry. With that data the pitch diameter and the number of grooves are defined. During installation, check the alignment between pulleys, the belt tension and that the keys and set screws are properly tightened. Misalignment, even slight, shortens belt life and punishes the shaft bearings.

If you need a different size, a nearby diameter or more grooves, send us the part number POLEA 340 3B or the data of the pulley you are replacing. With the diameter, section and number of grooves we can verify the equivalence within our in-house manufacturing line. If you have the original pulley at hand, also send us the bore diameter and the type of shaft fixing to confirm that the part fits without modification.
