The AirTAC SAI50 Standard Cylinder SAI50AX45S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø50mm bore and 45mm stroke, G1/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAI50X45-S is a double-acting ISO 15552 profile cylinder engineered for precise short-stroke actuation. Delivering a push force of 982 N at 0.5 MPa, it handles compact positioning tasks with repeatable accuracy. The 45 mm stroke is ideal for clamping, ejecting, and gating operations where space is restricted.
This variant includes a piston magnet for direct mounting of CMSE or DMSE reed switches along the extruded aluminum barrel grooves. It is configured with a SUS420J2 stainless steel rod for enhanced corrosion resistance and utilizes PT tapered port threads to ensure a robust, leak-free pneumatic connection.

Related SAI-family variants: SAID (double rod), SAIJ (adjustable stroke), SAIL (with lock), SAIF (with valve), BSAI (enclasp / clamp-lock), and SAI-S with built-in magnet. Rod material: carbon steel (blank) / SUS420J2 (A) / SUS304 (B); seals: TPU (blank) / Viton H / NBR N.
Provides rapid 45 mm ejection strokes to push machined components out of fixtures, utilizing 982 N of force to reliably dislodge stuck parts.
Actuates short-stroke gating mechanisms on packaging lines to redirect products, benefiting from the compact 50 mm profile and integrated position sensing.
Secures workpieces during light machining or welding processes, applying stable holding force while taking up minimal floor space.
Choose this 50 mm bore when 40 mm cylinders (628 N push at 0.5 MPa) lack the necessary thrust, but a 63 mm bore (1559 N) would be physically oversized. The 45 mm stroke provides exact travel for short movements without wasting cycle time. Because the stroke is under 300 mm, rod bearing bending is minimal, making it highly suitable for standard side loads.
As a true ISO 15552 profile cylinder, it offers a direct dimensional replacement for any standard 50 mm bore ISO 15552 unit. To maintain position safely without continuous air pressure, pair this cylinder with an external pilot-operated check valve or specify the SAIL lock variant. Mounting options include FA/FB flanges or LB foot brackets, and the integrated magnet enables seamless end-of-stroke sensing.
Quick checklist
At a standard operating pressure of 0.5 MPa, this 50 mm bore cylinder generates a push force of 982 N and a pull force of 825 N.
Yes. The SAI50X45-S is a genuine ISO 15552 profile cylinder, meaning its mounting dimensions are fully interchangeable with other ISO 15552 compliant cylinders of the same bore size.
