About the Airtac SAI32 Standard Cylinder SAI32AX65S
The AirTAC SAI32X65-S is a double-acting ISO 15552 profile cylinder engineered for compact, standardized automation. Delivering a push force of 402 N at 0.5 MPa, this 32 mm bore unit is tailored for short 65 mm stroke movements. Its extruded aluminum barrel design omits tie-rods, providing a clean exterior that drops directly into existing ISO 15552 mounting footprints.
This specific configuration includes a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. Equipped with a magnet (-S), it supports CMSE and DMSE sensor switches that seat neatly into the dual grooves machined on both sides of the barrel. Fluid ports feature PT tapered threads.

Where the Airtac SAI32 Standard Cylinder SAI32AX65S Is Used
Small Part Ejection
Provides the precise 402 N output needed to push lightweight plastic or aluminum parts out of a machining center.
Package Diverting
Actuates a short 65 mm stroke diverter arm to route small cartons on a packaging line without taking up excess space.
Clamp Actuation
Secures delicate workpieces in assembly fixtures where the SUS420J2 stainless rod prevents corrosion from occasional coolant exposure.
Is the Airtac SAI32 Standard Cylinder SAI32AX65S the Right Cylinder?
Select this 32 mm bore when an application demands exactly 402 N of push force at 0.5 MPa. If your fixture requires less energy, stepping down is not an option as 32 mm is the smallest SAI size; however, you can step up to the 40 mm bore (628 N push @ 0.5 MPa) if the load demands greater thrust. The 65 mm stroke keeps the rod fully supported without significant bending moments, so side-load concerns are minimal.
Because this is a double-acting pneumatic cylinder, it relies on continuous air pressure to hold position. If power drops or the valve centers, the piston will drift; for loads requiring dead-stop holding, consider the SAIL variant with an air-released lock or an external pilot check valve. For direct replacements, match the 32 mm bore, 65 mm stroke, PT G1/8 port, and desired mounting accessory like an LB foot or FA flange.
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 SAI32AX65S FAQ
At 0.5 MPa, this cylinder provides a push force of 402 N and a pull force of 345 N. If you increase the operating pressure to 0.7 MPa, the push force rises to 563 N.
Yes, the SAI32X65-S is dimensionally interchangeable per ISO 15552. You can drop it into existing foot, flange, or trunnion mounts designed for standard 32 mm bore profile cylinders, provided you match the G1/8 PT ports.
