The AirTAC SAI32 Standard Cylinder SAI32BX400 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 400mm 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 SAI32X400 is a double-acting ISO 15552 profile cylinder engineered for applications requiring a 400mm stroke. It generates 402N of push force at 0.5 MPa, scaling up to 724N at 0.9 MPa. This makes it well-suited for mid-distance material transfer and actuation tasks. As a genuine AirTAC component, it ensures reliable pneumatic performance.
Unlike standard models, this specific configuration utilizes a SUS304 stainless steel rod (material code B) for superior corrosion resistance in humid or mildly chemically washed environments. It features PT tapered port threads and lacks a standard magnet, meaning it is optimized for pure mechanical force delivery without integrated sensor switching.

Pushes light cardboard cartons across a 400mm transfer gap with precise 402N force at 0.5 MPa.
Ejects stamped small parts from a press bed, utilizing the SUS304 rod to resist cutting fluid splash.
Opens and closes lightweight gravity-feed bin gates over a 400mm span in dry bulk handling systems.
Selecting this 32mm bore over the neighboring 40mm option trades a bit of thrust (the 40mm bore provides 628N at 0.5 MPa) for a more compact footprint, which is often necessary in tight machine layouts. Because this unit features a 400mm stroke, the extended rod is susceptible to bending under side loads. To prevent premature rod-bearing wear, implement an external guide rail or choose a fully guided cylinder for heavy off-center loads.
If your workflow demands that the load stays fixed when air pressure is removed, this standard cylinder will drift; you should specify the SAIL variant with an air-released lock or use an external pilot-operated check valve. For direct mounting interchangeability, this SAI32X400 matches standard ISO 15552 dimensions, uses a G1/8 port, accepts standard FA/FB flanges, and can be upgraded with an -S magnet if sensor tracking is later required.
Quick checklist
At 0.5 MPa it provides 402N of push force and 345N of pull force. If you increase the pressure to 0.7 MPa, the push force rises to 563N.
Yes, the SAI32X400 is dimensionally interchangeable per ISO 15552. You can drop it in as a replacement for other ISO 15552 profile cylinders, provided your mounting interface and G1/8 port align.
