This EMMAR pulley is a power transmission component that mounts on a shaft to drive V-belts. With a 400 mm diameter, a single groove, and section A profile, it suits machines that need a straightforward, reliable link between shafts. Because it is made in-house, dimensions and balance are controlled so the belt runs true and vibration stays low.
The code PULLEY 400 1A tells you the three key details: outside diameter, number of grooves, and the belt section it takes. Section A is a classic narrow V-belt profile for medium-power drives. With only one groove, this pulley is chosen when a single belt is enough to carry the load.
You will find it on fans, centrifugal pumps, screw compressors, light conveyors, and machine tools. It also appears in plant equipment where speed is adjusted by swapping the driving or driven pulley diameter. The 400 mm size is common in assemblies running at moderate shaft speeds where a specific ratio is required.
When selecting and mounting, confirm the shaft diameter matches the pulley bore and that the keyway fits. The pulley is held with a key and set screw or with a taper bushing, depending on the hub style. Check alignment between pulleys with a straightedge or laser to prevent uneven belt wear. Set belt tension to the belt manufacturer's recommendation—neither too loose nor too tight.
