About the Airtac SAI32 Standard Cylinder SAI32AX25
The AirTAC SAI32X25 is a double-acting ISO 15552 profile cylinder engineered for compact actuation. It delivers a push force of 402 N at 0.5 MPa, making it well-suited for short-travel clamping and ejection tasks. The 25 mm stroke provides rapid response in tight machinery spaces without sacrificing standardized mounting dimensions.
This specific configuration utilizes an SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. Fluid compatibility is limited to filtered air, and the extruded aluminum barrel features integrated sensor grooves on both sides for straightforward position detection.

Where the Airtac SAI32 Standard Cylinder SAI32AX25 Is Used
Short-Stroke Clamping
Ideal for securing small workpieces during machining operations where a 402 N force is sufficient and space is restricted.
Package Ejection
Provides rapid 25 mm ejection strokes on packaging lines to divert lightweight cartons off a main conveyor belt.
Valve Actuation
Serves as a compact pneumatic actuator for automated process valves requiring quick, repeatable on-off positioning.
Is the Airtac SAI32 Standard Cylinder SAI32AX25 the Right Cylinder?
Select this 32 mm bore model when an application requires precise point-to-point movement in a confined footprint. If your assembly requires slightly higher force, stepping up to the 40 mm bore yields 628 N at 0.5 MPa. Conversely, if the 25 mm stroke is insufficient for your travel path, longer standard strokes up to 1000 mm are available within this bore series.
Because the stroke is only 25 mm, side-load stress on the rod bearing is minimal. However, operators should note that this standard cylinder relies on adjustable air cushions at both ends to decelerate the piston. It will not hold a load in place upon loss of air pressure; for position holding, consider the SAIL variant with an air-released lock.
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 SAI32AX25 FAQ
