Schrader Bellows FW2B118521 Pneumatic Air Cylinder

Schrader Bellows FW2B118521 Pneumatic Air Cylinder is an Econo-Ram II Series single-rod-end actuator designed for economical, NFPA-compatible linear motion in light- to medium-duty automation. This model pairs an extruded aluminum body with a 3-1/4" bore and an 18" stroke to deliver repeatable push or pull strokes, and it features cap-detachable clevis mounting (MP2) for flexible installation, a 1" piston rod with a 3/4-16 small male rod thread, and a 1/2" NPTF air port for supply. Sealing uses Buna-N elastomer seals and the cylinder is non-cushioned, with no bumpers installed in the base configuration. The Econo-Ram II line is designed to be economical while offering long service life in a compact package, making it suitable for part transfer, clamping, or actuation in automated tooling and assembly setups where NFPA compatibility matters. This model reflects Schrader Bellows’ emphasis on reliable, simple pneumatic actuation with a smooth body that minimizes contamination and eases maintenance, and it is compatible with standard mounting configurations across the Econo-Ram II family to enable straightforward integration into existing systems requiring a mid-duty cylinder with a detachable-cap mounting and standard rod-end connection.
