Bimba Manufacturing F03-1251 Pneumatic Cylinder

The BIMBA FO3-1251-4M Flat-1 stainless steel pneumatic cylinder is a double‑acting actuator in the Flat‑1 family designed for compact, multi‑stage extension in tight spaces. It features a 4‑inch bore and a 1‑inch stroke, delivering three‑stage extend action with a single‑stage retract, making it suitable for precise, staged positioning in constrained layouts. The cylinder uses a 304 stainless steel body and a 303 stainless steel piston rod for corrosion resistance, with Buna‑N seals to maintain reliable sealing across cycles. A magnet is integrated for piston‑position sensing, enhancing feedback in control systems. The unit is configured as a single‑end rod model with screw clearance holes at both ends for mounting, and it provides a 3/8‑inch NPT threaded pneumatic port along with a 3/4‑16 UNF female thread on the rod end for end fittings or accessories. This FO3‑1251‑4M variant is listed within Bimba’s Flat‑1 Multiple Power series, combining stainless steel construction with a compact footprint and multi‑position extend capability for reliable actuation in automation applications.
