Allenair AD-1-1 1 8-P Brass Pneumatic Cylinder

The Allenair AD-1-1 1-1/8-P Brass Pneumatic Cylinder is a compact, double-acting small-bore actuator with a 1-1/8 in bore and a 1 in stroke, designed for precise, repeatable linear motion in tight spaces. Built around a brass tube, the bore is precision honed and finished with a cross-hatch lubricant-retaining pattern, while the front and rear heads are machined and threaded for durable assembly and serviceability. The piston rod is 3/8 inch in diameter and is threaded on one end. Rated for up to 150 psi in pneumatic or hydraulic service, this cylinder supports light-duty automation, positioning, and fixture actuation in compact installations. It belongs to Allenair's small-bore family (bores of 1/2", 3/4", and 1-1/8" with strokes up to 14"), known for replaceable seals and brass construction that withstands routine maintenance and rebuilds. The AD designation identifies a double-ended design within Allenair's cylinder lineup, offering reliable performance in space-constrained applications.
