About the Airtac SAI32 Standard Cylinder SAI32AX90S
The AirTAC SAI32X90-S is a double-acting ISO 15552 profile cylinder engineered for compact automation. Delivering a push force of 563 N at 0.7 MPa, this 32 mm bore unit is tailored for precise 90 mm stroke movements. The extruded aluminum barrel omits tie-rods, providing a clean profile that drops directly into standardized ISO 15552 mounting footprints.
This specific configuration includes a SUS420J2 stainless steel piston rod (material code A) for superior corrosion resistance compared to standard carbon steel. Equipped with a magnet (-S), it seamlessly integrates with CMSE and DMSE sensor switches fitted into the dual side grooves. Fluid ports feature PT tapered threads, and adjustable air cushions at both ends ensure smooth end-of-stroke deceleration.

Where the Airtac SAI32 Standard Cylinder SAI32AX90S Is Used
Small Part Ejection
Provides reliable 402 N push force at 0.5 MPa to eject small molded components from machining fixtures.
Package Diverting
Actuates a 90 mm stroke diverting arm on a packaging line, utilizing the integrated magnet for position confirmation.
Clamp Actuation
Drives lightweight pneumatic clamps in assembly jigs where the SUS420J2 stainless rod resists workshop humidity.
Is the Airtac SAI32 Standard Cylinder SAI32AX90S the Right Cylinder?
Selecting this 32 mm bore makes sense when your application demands 563 N of push force at 0.7 MPa. If your load requires less energy, stepping down is unfeasible as 32 mm is the smallest standard SAI size; however, if you need substantially more thrust, consider the 40 mm bore which provides 879 N at 0.7 MPa. The 90 mm stroke is well below the 300 mm threshold, so rod-bearing bending from side loads is minimal, though external guides remain best practice for rigid payload tracking.
Because it is a standard double-acting cylinder, the SAI32X90-S relies entirely on continuous air pressure to hold its position. If pneumatic supply is lost or the control valve centers, the piston will drift. For applications requiring true load holding without live pressure, specify the SAIL variant with an air-released lock or utilize an external pilot-operated check valve. Replacement is straightforward: match the 32 mm bore, 90 mm stroke, PT port thread, and choose appropriate FA flange or LB foot mounting accessories.
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 SAI32AX90S FAQ
