About the Airtac SAI32 Standard Cylinder SAI32X90S
The AirTAC SAI32X90-S is a double-acting ISO 15552 profile cylinder offering 402N push force at 0.5 MPa and a 90mm stroke. The extruded aluminum barrel lacks tie-rods, presenting a clean exterior that drops directly into standardized ISO 15552 mounting interfaces.
This specific configuration includes a magnetic piston (-S) for position feedback and uses a standard carbon steel piston rod. It features PT tapered G1/8 ports and adjustable air cushions at both ends to dampen impact. For higher temperature environments up to 70 C, Viton (H) seals are available as an alternative to the standard TPU.

Where the Airtac SAI32 Standard Cylinder SAI32X90S Is Used
Small Part Clamping
Provides reliable 402N clamping force at 0.5 MPa for securing small machined components during light milling or drilling operations.
Package Sorting Diverter
Uses the 90mm stroke and magnetic piston for fast, position-verified diverting of lightweight cardboard packages on logistics conveyor lines.
Pneumatic Ejector
Ejects small plastic injection molded parts from tooling cavities, utilizing adjustable end cushions to prevent part damage during ejection.
Is the Airtac SAI32 Standard Cylinder SAI32X90S the Right Cylinder?
Select this 32mm bore when your application requires less force than the 40mm bore (628N at 0.5 MPa) but more than smaller compact cylinders. The 90mm stroke is non-standard but falls well within the 1000mm maximum limit for this bore. Because the stroke is under 300mm, side-load bending on the rod bearing is minimal, though external guides are recommended for heavy lateral loads.
This cylinder does not hold its position if air pressure drops; the piston will drift. Use an external pilot-operated check valve or the SAIL locking variant if fail-safe load holding is required. Replacement is straightforward: match the 32mm bore, 90mm stroke, PT G1/8 port, and mounting accessory (like an FA flange or LB foot), and ensure the -S magnet is specified if sensors are used.
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 SAI32X90S FAQ
At a standard 0.5 MPa operating pressure, the push force is 402N and the pull force is 345N. If pressure is increased to 0.7 MPa, the push force rises to 563N.
Yes, the SAI32X90-S is dimensionally interchangeable per ISO 15552. You can replace other ISO 15552 profile cylinders of the same 32mm bore and 90mm stroke by matching the PT G1/8 port and standard mounting accessories.
