ARO 3940-1089-1-160 Provenair Pneumatic Air Cylinder

The ARO 3940-1089-1-160 Provenair Pneumatic Air Cylinder delivers precise linear motion with a 4-inch bore, a 16-inch stroke, and a 1-inch shaft, making it suitable for compact, high-velocity actuation in automation systems. As part of the Provenair line from ARO, this cylinder relies on compressed air to extend and retract a piston rod, providing clean, repeatable motion in confined spaces. In pneumatic cylinders, bore size sets potential force output and rigidity, while stroke length determines travel distance; with a 4-inch bore and 16-inch stroke, this model offers a balance of power and reach for moderate- to long-travel actuation. The 1-inch shaft diameter specifies the rod size used to transmit motion to connected components. One practical implication of this configuration is that it fits applications where a mid-range bore and a relatively long stroke are beneficial, while maintaining a compact overall footprint. The 3940-1089-1-160 configuration identifies the exact unit within the Provenair family.
