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.\u003c\/p\u003e\u003c\/div\u003e","brand":"Aro","offers":[{"title":"New","offer_id":51660133433646,"sku":null,"price":85.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_487bf6d7-4f12-481e-ba0a-22882b56d79a.jpg?v=1769533343","url":"https:\/\/plgautomation.com\/products\/aro-3940-1089-1-160-provenair-pneumatic-air-cylinder","provider":"PLG Automation ","version":"1.0","type":"link"}
