About the Airtac SAI100 Standard Air Cylinder SAI100X70S
The AirTAC SAI100X70-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 3927 N of push force at 0.5 MPa, this 100 mm bore unit is built around an extruded aluminum barrel with a standard 70 mm stroke. The integrated magnet (-S) enables seamless position detection using CMSE or DMSE sensor switches along the dual side grooves.
Equipped with a standard carbon steel piston rod and PT tapered port threads, it ensures durable mechanical performance and leak-free pneumatic connections. This genuine AirTAC component serves as a dimensionally interchangeable drop-in replacement for any standard ISO 15552 cylinder, providing high power without requiring custom mounting plates.

Where the Airtac SAI100 Standard Air Cylinder SAI100X70S Is Used
Heavy-Duty Stamping
Provides the necessary 3927 N push force at 0.5 MPa to execute short-stroke stamping and forming operations on thick metal panels.
Pallet Diverting
Drives robust routing arms on high-mass conveyor lines, utilizing the 70 mm stroke to push heavy pallets onto side transfer tracks.
Injection Mold Ejection
Delivers consistent ejection force for large molded parts, using the integrated magnet and CMSE sensors to confirm part release.
Is the Airtac SAI100 Standard Air Cylinder SAI100X70S the Right Cylinder?
Selecting this 100 mm bore model is optimal when your application requires upward of 3927 N of thrust at 0.5 MPa but does not need the full 5497 N push force generated by operating at 0.7 MPa. If your load requirements are lighter, stepping down to an 80 mm bore yields 2513 N at 0.5 MPa, conserving air volume. Conversely, applications demanding extreme push power should consider the 125 mm bore, which provides 6136 N at 0.5 MPa.
Because the stroke is only 70 mm, side-load stress on the rod bearing is minimal compared to longer strokes. Note that the adjustable air cushions at both ends decelerate the piston near the end of travel but do not lock the load; if your system loses air pressure, the rod will drift. For position holding without live pressure, explore the SAIL or BSAI locking variants.
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 SAI100 Standard Air Cylinder SAI100X70S FAQ
At a standard operating pressure of 0.5 MPa, this 100 mm bore cylinder generates 3927 N of push force and 3681 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 5497 N.
Yes, the SAI100X70-S is a true ISO 15552 profile cylinder. Its standardized mounting dimensions and G1/2 (PT) ports make it dimensionally interchangeable with other ISO 15552 cylinders, serving as a direct drop-in replacement.
