Allenair 118X112 Pneumatic Cylinder

Allenair A118X112 Pneumatic Cylinder is a compact general‑purpose actuator that delivers reliable linear motion in tight spaces. The model designation A118X112 corresponds to a 1-1/8 in bore and a 1-1/2 in stroke, offering a practical combination of small footprint and usable travel for a variety of automation tasks. This unit is manufactured by Allenair, a U.S.–based supplier known for its broad line of pneumatic cylinders, and it ships pre‑lubricated at assembly with Buna‑N (Nitrile) seals. Allenair specifies Buna‑N seals and lubrication guidance for its standard cylinders, supporting predictable performance across typical shop air pressures and operating temperatures (Buna‑N seals cover a broad range from −40°F to +250°F). For customization, Allenair provides configurator tools for its Type A, C, and E cylinder families to tailor mounting, end‑caps, and accessories to specific installations. The A118X112 sits within Allenair’s broader cylinder portfolio, which emphasizes proven, domestically engineered components and compatibility with standard mounting patterns and accessory options. This makes it suitable for light‑ to moderate‑duty actuation in applications such as positioning, indexing, clamping, and tool actuation where a compact, air‑powered cylinder is advantageous.
