About the Airtac SAI32 Standard Cylinder SAI32AX40S
The AirTAC SAI32X40-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 40 mm stroke movements. The extruded aluminum barrel eliminates tie-rods, providing a clean profile that drops directly into any ISO 15552 mounting interface.
This specific configuration includes a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance over standard carbon steel. Equipped with a magnet (-S), it supports CMSE and DMSE sensor switches that seat neatly into the dual grooves on the barrel. Fluid ports feature a PT tapered thread type, ensuring a robust pneumatic seal.

Where the Airtac SAI32 Standard Cylinder SAI32AX40S Is Used
Small Part Ejection
Provides rapid 40 mm strokes to push lightweight finished parts out of machining centers.
Package Diverting
Actuates short-stroke routing gates to sort small packages on high-speed conveyor lines.
Clamp Actuation
Drives small pneumatic clamps holding delicate workpieces during light assembly tasks.
Is the Airtac SAI32 Standard Cylinder SAI32AX40S the Right Cylinder?
Select this 40 mm stroke model when a brief, precise actuation is required without the bulk of longer strokes. If your application demands less than 402 N of push force at 0.5 MPa, stepping down is unnecessary as this is the smallest standard SAI bore. Conversely, if higher kinetic energy is needed, stepping up to the 40 mm bore yields 628 N.
Because the standard SAI is double-acting, it relies entirely on continuous air pressure to maintain its position. If air is exhausted or the valve centers, the piston will drift. For tasks that must hold a load mechanically without live pressure, integrate the SAIL (air-released lock) variant or an external rod lock. To replace an existing unit, match the 32 mm bore, 40 mm stroke, PT G1/8 port, and mounting accessory.
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 SAI32AX40S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder 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 SAI32X40-S is a true ISO 15552 profile cylinder, making its mounting dimensions fully interchangeable with other ISO 15552 cylinders of the same bore and stroke. Always confirm your port and thread specifications.
