About the Airtac SAI32 Standard Cylinder SAI32AX425
The AirTAC SAI32X425 is a double-acting ISO 15552 profile cylinder engineered to deliver 563N of push force at 0.7MPa. Utilizing an extruded aluminum barrel without tie-rods, it provides a standardized mounting interface that is dimensionally interchangeable with other ISO 15552 actuators. The 425mm stroke is well-suited for mid-range linear transfer tasks.
This specific configuration features a SUS420J2 stainless steel piston rod for enhanced corrosion resistance compared to standard carbon steel. It uses PT tapered port threads, and because it lacks the -S magnet suffix, it does not have integrated sensor grooves equipped for reed switches like CMSE or DMSE.

Where the Airtac SAI32 Standard Cylinder SAI32AX425 Is Used
Package Sorting
Drives pushing arms at 425mm stroke to divert small to medium parcels on standard distribution conveyors.
Component Ejection
Ejects machined parts from a fixture with 563N of force at 0.7MPa, utilizing the corrosion-resistant SUS420J2 rod.
Material Handling
Actuates mid-length lifting gates or pneumatic stops to regulate workflow on automated assembly lines.
Is the Airtac SAI32 Standard Cylinder SAI32AX425 the Right Cylinder?
For applications requiring less extension, stepping down to the neighboring 32mm bore stroke options preserves the 402N push force at 0.5MPa while reducing overall footprint. Because this 425mm stroke exceeds 300mm, the unsupported piston rod is highly susceptible to bending under side loads. To prevent premature rod-bearing wear, implement an external guide rail or select a guided cylinder module.
Ensure your replacement matches the 32mm bore, 425mm stroke, G1/8 port, and appropriate mounting accessories like LB foot brackets or FA flanges. Note that this standard cylinder relies on air pressure to maintain position; if pneumatic supply is lost, the load will drift. For fail-safe holding, consider the SAIL variant with an air-released lock or an external pilot-operated check valve.
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 SAI32AX425 FAQ
The SAI32X425 provides a push force of 563N at 0.7MPa and 724N at 0.9MPa. The pull force at 0.5MPa is 345N.
No, the standard SAI cylinder will drift if air pressure is lost or exhausted. You must use the SAIL variant with a lock or an external rod lock to hold loads safely.
