About the Airtac SAI32 Standard Cylinder SAI32X25S
The AirTAC SAI32X25-S is a double-acting ISO 15552 profile cylinder featuring a 32mm bore and a 25mm stroke. It delivers a push force of 402 N at 0.5 MPa, making it well-suited for compact, short-stroke automation tasks. The extruded aluminum barrel design omits tie rods for a cleaner profile while maintaining strict dimensional interchangeability per ISO 15552.
Equipped with a magnetic piston (-S), this model supports CMSE and DMSE sensor switches via dual grooves on the barrel. It uses standard carbon steel for the rod and features PT tapered port threads, ensuring reliable pneumatic connections in tight machinery layouts.

Where the Airtac SAI32 Standard Cylinder SAI32X25S Is Used
Small Part Ejection
Ideal for pushing small machined components out of a fixture quickly within a 25mm travel distance.
Packaging Clamping
Provides reliable 402N holding force for securing light packaging materials during sealing or labeling.
Sensor Actuation
The integrated magnet allows precise end-of-stroke detection using CMSE sensors in automated assembly lines.
Is the Airtac SAI32 Standard Cylinder SAI32X25S the Right Cylinder?
Choose this 32mm bore when your application requires 402 N of push force at 0.5 MPa. If your layout needs less force, stepping down is not an option below 32mm in the SAI series, but if you need higher thrust, the 40mm bore provides 628 N. The 25mm stroke is ideal for rapid clamping or ejection, operating efficiently within the 30-800 mm/s speed range.
Because the SAI32X25-S is a double-acting cylinder, it relies on continuous air pressure to hold position; it will drift if pressure is lost. For direct replacements, verify the ISO 15552 mounting dimensions, PT port size (G1/8), and required accessories like LB foot brackets or FA flanges.
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 SAI32X25S FAQ
At an operating pressure of 0.5 MPa, the SAI32X25-S provides a push force of 402 N and a pull force of 345 N. At 0.7 MPa, the push force increases to 563 N.
Yes, the SAI32X25-S is dimensionally interchangeable per ISO 15552. You can drop it in place of other ISO 15552 profile cylinders with a 32mm bore and 25mm stroke, provided your port and mounting dimensions match.
