About the Airtac SAI32 Standard Cylinder SAI32AX25S
The AirTAC SAI32X25-S is a double-acting ISO 15552 profile cylinder engineered for compact, space-constrained pneumatics. Delivering 402N of push force at 0.5 MPa, this 32mm bore unit is built around an extruded aluminum barrel rather than traditional tie-rods. The 25mm stroke provides rapid, short-range linear movement for high-cycle automated machinery.
This specific configuration includes a -S magnet for use with CMSE and DMSE series reed switches, which seat neatly into the integrated sensor grooves on both sides of the barrel. The piston rod is constructed from SUS420J2 stainless steel (material code A) for superior corrosion resistance compared to standard carbon steel, while the PT tapered port threads guarantee a robust, leak-free pneumatic connection.

Where the Airtac SAI32 Standard Cylinder SAI32AX25S Is Used
Short-Stroke Clamping
Ideal for small fixture clamping in CNC machining where a fast 25mm stroke and 402N force securely hold light components without occupying excessive fixture space.
Package Diverters
Drives compact diverter arms on packaging conveyor lines, using the integrated -S magnet and CMSE switches to confirm actuation end-positions instantly.
Valve Actuation
Provides reliable linear actuation for small process valves, relying on the SUS420J2 stainless rod to resist minor moisture and environmental corrosion.
Is the Airtac SAI32 Standard Cylinder SAI32AX25S the Right Cylinder?
At 0.5 MPa, this 32mm bore yields 402N of push and 345N of pull force. If your assembly requires less force, stepping down is not an option as 32mm is the smallest SAI bore; however, if you need to move heavier payloads, the 40mm bore provides 628N of push force at the same pressure. For this 25mm stroke, side loading is minimal, but always ensure the load is axially aligned to prevent premature rod-bearing wear. Because this is a double-acting cylinder, it relies on continuous air pressure to hold position. If your mechanism must lock or hold a load safely during an air loss event, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants. To match this ISO 15552 mounting interface, you can pair it with LB foot brackets, FA/FB flanges, or TC trunnion joints depending on your pivot requirements.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAI32 Standard Cylinder SAI32AX25S FAQ
At 0.5 MPa operating pressure, the 32mm bore generates 402N of push force and 345N of pull force. At the maximum 1.0 MPa pressure, the theoretical push force reaches 801N.
Yes. The SAI32X25-S is a genuine ISO 15552 profile cylinder, making its mounting dimensions completely interchangeable with other ISO 15552 cylinders of the same bore size, such as those from Festo or SMC.
