The AirTAC SAI32 Standard Cylinder SAI32BX40 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 40mm 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 SAI32X40 is a double-acting ISO 15552 profile cylinder featuring a compact 40mm stroke. It generates 402N of push force at 0.5 MPa, making it well-suited for tight automation spaces requiring precise short movements. The extruded aluminum barrel design omits tie rods for a clean exterior.
This specific unit is configured with a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance. It utilizes PT tapered port threads and does not include a magnet. For high-temperature environments up to +70 C, the seal options can be upgraded from standard TPU to Viton (H).

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 reliable 402N push force to eject small machined components from a fixture using a short 40mm stroke.
Actuates a lightweight diverter gate to route small boxes on a conveyor line without occupying excessive footprint.
Drives small pneumatic clamps to hold delicate workpieces securely in place during light assembly processes.
Choose this 32mm bore when an application demands 402N of push force at 0.5 MPa. If your fixture requires less energy, stepping down is an option, but moving up to a 40mm bore provides 628N at the same pressure. The PT port thread standardizes your pneumatic connections.
Because the stroke is only 40mm, side-load stress on the rod bearing is minimal. Note that this standard cylinder relies on air pressure to maintain position; if air is lost, the load will drift. For applications requiring dead-stop holding without live pressure, consider the SAIL variant with an air-released lock. To mount this ISO 15552 unit, select FA or FB flanges, and add the -S magnet suffix if CMSE or DMSE sensors are needed.
Quick checklist
At an operating pressure of 0.5 MPa, this 32mm bore cylinder provides a push force of 402N. If pressure is increased to 0.7 MPa, the push force rises to 563N.
Yes, the SAI32X40 is dimensionally interchangeable per ISO 15552. It serves as a direct replacement for other standard ISO 15552 profile cylinders of the same bore and stroke, utilizing PT port threads.
