Allenair AP 1-1 2x3 BCFXx4 FCFX NT #121 Cylinder

The Allenair AP-series cylinder is a compact, single-ended three-position pneumatic actuator built around a 1-1/8" bore (code 121) and offered with the NT option (no tang). In AP configurations, two piston-rod assemblies create three distinct positions with positive stops, and customers can order a range of stroke combinations, including the common practice of selecting a first stroke plus a total stroke. Made in the USA as part of Allenair’s small-bore cylinder lineup, it supports bores of 1/2", 3/4", and 1-1/8" with strokes up to 14" and comes pre-lubricated at assembly with Buna-N seals rated for temperatures from -40°F to +250°F. The cylinder family is designed for reliable industrial automation, and options such as Valve-in-Head configurations let you integrate actuation and control in a compact module while maintaining the AP’s three-position, two-rod architecture.
