The unit is specified as AD118X4 (A-1-1\/8X4 in some listings), indicating an AD-series cylinder with a 4-inch stroke. The nominal stroke is 4 inches, but, per Allenair reference notes for AD-type cylinders, about 3\/32 inch of stroke is lost to piston construction, giving an effective travel of roughly 3.906 inches. A variant exists as A-1-1\/8X4-NT, a no-thread version, showing that this model family includes different mounting options. Allenair catalogs describe small-bore cylinders in 1\/2 inch to 1-1\/8 inch bores with strokes up to 14 inches and emphasize the series’ suitability for compact installations where dependable pneumatic actuation is required. The AD118X4 typically accepts standard pneumatic fittings and valve configurations within Allenair’s product ecosystem; for exact port styles, mounting face dimensions, and accessory compatibility, refer to the official Allenair catalog or the retailer’s specification sheet for A118X4\/AD118X4 models. This cylinder is well-suited for push\/pull tasks, precise positioning, and repeatable actuation in machines where space is at a premium and consistent stroke is essential.\u003c\/p\u003e\u003c\/div\u003e","brand":"ALLENAIR","offers":[{"title":"New","offer_id":51659790713134,"sku":null,"price":37.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_21256901-5f9e-4bee-bda8-fb7654c87ace.jpg?v=1769529924","url":"https:\/\/plgautomation.com\/products\/industrial-ad118x4-pneumatic-cylinder-actuator","provider":"PLG Automation ","version":"1.0","type":"link"}
