The industrial pulley with 400 mm diameter, 1 groove and section A is a power transmission component mounted on shafts to drive V-belts. It is used in machines and equipment that need to transmit motion between shafts simply and reliably. Being in-house manufactured, EMMAR brand, dimensions and balancing are controlled so the belt seats well and the equipment runs without unnecessary vibrations.

This item is a pulley with 400 mm diameter, 1 groove and section A. The designation PULLEY 400 1A summarizes these three characteristics: outside diameter, number of grooves and the belt section it accepts. Section A corresponds to classic V-belts with a narrow profile, suitable for medium power transmissions. Having a single groove, it is used when the power to be transmitted does not require multiple belts in parallel.

Typical applications include fans, centrifugal pumps, screw compressors, light conveyors and machine tools. It is also used in factory equipment and installations where the output speed needs to be varied by changing the diameter of the driving or driven pulley. Due to its diameter, it is common in assemblies where the shaft rotates at moderate speeds and a specific transmission ratio is sought.

To select and mount this pulley, verify that the shaft diameter matches the pulley bore and that the keyway is compatible. The pulley is fixed with a key and set screw or with a taper bushing, depending on the hub design. Check alignment between pulleys with a straightedge or laser to avoid uneven belt wear. Belt tension should be as recommended by the belt manufacturer, neither loose nor excessive.
