The AirTAC SAI32 Standard Cylinder SAI32BX45S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 45mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAI32X45-S is a double-acting ISO 15552 profile cylinder engineered for compact automation. Delivering a push force of 402 N at 0.5 MPa, this 32 mm bore unit is tailored for short 45 mm stroke movements where spatial constraints are tight. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that simplifies mounting and sensor placement.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance and a built-in magnet (-S) for seamless integration with CMSE or DMSE reed switches along the dual sensor grooves. It is a genuine AirTAC component built to deliver consistent pneumatic performance in demanding environments.

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.
Ideal for securing delicate electronic components during assembly, utilizing the 45 mm stroke to actuate compact clamping jaws with precise force control.
Provides rapid actuation for lightweight diverter arms on packaging lines, where the 32 mm bore delivers sufficient thrust without bulk.
Suitable for pushing small molded parts out of machining cells, leveraging the SUS304 rod to resist moisture and coolant splash.
Choose this 32 mm bore when an application requires precise short-stroke actuation up to 45 mm. If the workload demands less force, stepping down is not an option as 32 mm is the smallest standard SAI size, but stepping up to the 40 mm bore (628 N push at 0.5 MPa) is advised if margins are thin. Because the stroke is under 300 mm, side-load stress on the rod bearing is minimal, though external guides are always recommended for heavy off-center loads.
For ISO 15552 direct compatibility, ensure your mounting scheme matches standard accessories like LB foot brackets or FA flanges. The cylinder uses PT tapered port threads (G1/8) and requires the -S magnet suffix for position feedback. Note that standard SAI cylinders drift when air pressure is removed; use the SAIL variant with an air-released lock if the mechanism must hold a load safely during an outage.
Quick checklist
At 0.5 MPa, the push force is 402 N and the pull force is 345 N. If you increase the operating pressure to 0.7 MPa, the push force rises to 563 N.
Yes. The SAI32X45-S is dimensionally interchangeable per ISO 15552 standards. You can drop it into existing foot, flange, or clevis mounting setups designed for equivalent ISO profile cylinders.
