The 480 4B pulley is a V-belt drive pulley, manufactured by EMMAR Accesorios Industriales. It has a 480 mm diameter and 4 grooves, section B, which makes it suitable for transmitting power in equipment that requires several belts in parallel. It is used in fans, compressors, pumps and process machines where motion is taken from a motor and carried to a driven shaft. Its in-house construction allows the machining of the bore and keyway to be adapted to each application.

This pulley has a 480 mm diameter, 4 grooves and section B. Section B corresponds to classic-profile V-belts, and the 4 grooves allow four belts to be mounted in parallel on the same pulley. The 480 mm diameter defines the transmission ratio together with the driving pulley: the larger the diameter, the lower the speed on the driven shaft. The number of grooves affects the number of belts that take the load, which distributes the effort and improves drive continuity.

It is used in power transmission applications where it is necessary to reduce revolutions and maintain a stable regime. It is common in industrial fans, screw compressors, centrifugal pumps, mixers and conveyors. It also appears in process equipment that already has a smaller driving pulley and needs a 480 mm driven pulley with four belts to cover the required power. In all cases it is advisable to verify that the shaft and the pulley bore are compatible.

To select and mount this pulley, take into account the shaft diameter, the type of bore (cylindrical or tapered), the keyway and the fastening system. Check that the belt section is B and that the number of grooves matches the number of belts you are going to use. Check the alignment between pulleys: misalignment accelerates wear on the belts and the grooves. Tension must be the recommended one for section B, neither loose nor excessive, and it is advisable to check it after the first hours of operation.

If you need an equivalent pulley or a nearby size, send us the part number 480 4B or the diameter and number of grooves you are looking for. We can also evaluate variants in the number of grooves or in the diameter to adjust the transmission ratio. To do so, send us the equipment data: power, motor speed, driving pulley diameter and shaft diameter. With that information we guide you on the most convenient option within our in-house manufacturing line.
