About the Airtac SAI32 Standard Cylinder SAI32X70S
The AirTAC SAI32X70-S is a double-acting ISO 15552 profile cylinder engineered for compact automation. Delivering a push force of 402 N at 0.5 MPa, this 32 mm bore unit is tailored for short-stroke cycling. The extruded aluminum barrel omits tie-rods, providing a clean exterior that drops directly into standardized ISO 15552 mounting footprints.
Equipped with a magnetic piston (-S), this model seamlessly integrates with CMSE and DMSE reed switches via the dual sensor grooves machined into both sides of the barrel. It features a standard carbon steel piston rod and a PT tapered port thread, ensuring robust and leak-free pneumatic connections in general-purpose environments.

Where the Airtac SAI32 Standard Cylinder SAI32X70S Is Used
Component Ejection
Provides rapid 70 mm strokes to push small machined parts out of a fixture, using 402 N of force at 0.5 MPa to clear the workspace for the next cycle.
Package Diverting
Actuates a short-stroke routing gate on a packaging line, where the magnetic piston allows CMSE sensors to confirm gate position before products arrive.
Clamp Actuation
Drives small pneumatic clamps holding light sheet metal during assembly, benefiting from the compact 32 mm profile barrel to fit tight tooling spaces.
Is the Airtac SAI32 Standard Cylinder SAI32X70S the Right Cylinder?
Choose this 32 mm bore when an application requires roughly 400 N of linear force at 0.5 MPa. If your assembly needs less than 300 N, stepping down to a 25 mm bore saves space, while tasks exceeding 600 N require stepping up to a 40 mm bore. The 70 mm stroke is optimal for rapid, short-distance actuation without requiring extensive rod support.
Because it is a double-acting cylinder, the SAI32X70-S relies on continuous air pressure to hold its position; it will drift if pressure is lost. For vertical loads requiring fail-safe holding, consider the SAIL variant with an air-released lock. This unit serves as a direct dimensional replacement for any ISO 15552 cylinder with a 32 mm bore, 70 mm stroke, PT port, and a magnet.
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 SAI32X70S FAQ
At a standard operating pressure of 0.5 MPa, this 32 mm bore cylinder generates a push force of 402 N and a pull force of 345 N. If pressure is increased to 0.7 MPa, the push force rises to 563 N.
Yes, the SAI32X70-S is dimensionally interchangeable per ISO 15552. You can drop it directly into existing mounts matching a 32 mm bore, 70 mm stroke, and PT port configuration without modifying the machinery.
