The 380 3A pulley is a V-belt transmission pulley, manufactured by EMMAR Accesorios Industriales. It has a diameter of 380 mm, 3 grooves and section A, which makes it suitable for transmitting power in equipment working with section A belts. It is used in fans, compressors, pumps, mills and conveyors, where a stable transmission ratio and good belt grip are needed. Being of in-house manufacturing, the machining can be adjusted according to the equipment's needs.
This pulley has an outside diameter of 380 mm, 3 grooves and section A. The grooves are machined so that the V-belt seats evenly and does not slip. The body is made of cast iron or steel, as the case may be, and balancing is controlled so that there are no vibrations at the usual working speeds. It is supplied with the bore and keyway to be defined according to the equipment shaft. The part number POLEA 380 3A identifies this size and configuration.
Typical applications are belt transmission equipment: industrial fans, screw compressors, centrifugal pumps, mills, mixers and conveyors. It is also used in agricultural machinery and in process lines where speed needs to be reduced or increased between the motor and the driven machine. Having 3 grooves allows the load to be distributed among several belts, which extends the service life of the assembly and provides margin if one belt fails.
To select the pulley, take into account the shaft diameter, the type of keyway, the center distance and the transmission ratio you are looking for. Verify that the belt section matches section A and that the number of grooves is the one needed for the power to be transmitted. Mounting is done with the shaft clean and free of burrs, and the pulley must be aligned with the driving pulley to avoid uneven belt wear.
If you need an equivalent pulley or a nearby size, send us the part number POLEA 380 3A or the equipment data: diameter, grooves, section and shaft diameter. With that we will verify whether we have an in-house manufactured pulley that fits or whether it is better to machine a new one. We can also quote the complete assembly with belts and bushings if needed.
