The 380 3A pulley is a V-belt drive pulley, manufactured by EMMAR Accesorios Industriales. It has a 380 mm diameter, 3 grooves and section A, making it suitable for power transmission in equipment running with A-profile belts. It is used in fans, compressors, pumps, mills and conveyors, where a stable transmission ratio and good belt grip are required. As it is in-house manufactured, the machining can be adjusted to the equipment's needs.
This pulley has a 380 mm outside diameter, 3 grooves and section A. The grooves are machined so the V-belt seats evenly and does not slip. The body is cast iron or steel, depending on the case, and balancing is controlled to prevent vibration at normal operating 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 drive equipment: industrial fans, screw compressors, centrifugal pumps, mills, mixers and conveyors. It is also used in agricultural machinery and process lines where speed needs to be reduced or increased between the motor and the driven machine. With 3 grooves, it 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, keyway type, center distance and the transmission ratio you need. Verify that the belt section matches section A and that the number of grooves is sufficient 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 drive pulley to avoid uneven belt wear.
If you need an equivalent pulley, send us the part number POLEA 380 3A or the equipment data: diameter, grooves, section and shaft diameter. With that we will indicate the in-house manufactured pulley that fits or machine it to measure. We can also quote the complete assembly with belts and bushings if needed.
