About the Airtac SAI100 Standard Air Cylinder SAI100AX20
The AirTAC SAI100X20 is a double-acting ISO 15552 profile cylinder engineered for high-force, short-stroke operations. It supplies a robust 3927 N of push force at 0.5 MPa, making it ideal for heavy pressing and clamping tasks within confined spaces.
This specific configuration features an SUS420J2 stainless steel piston rod (material code A) for superior corrosion resistance. It utilizes PT tapered port threading and, because it lacks the -S magnet suffix, relies on external limit switches rather than barrel-mounted sensors.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX20 Is Used
Heavy-Duty Stamping
Provides the intense 3927 N impact force required for short-stroke metal stamping and riveting operations.
Pallet Clamping
Secures heavy pallets or large workpieces firmly in place during automated packaging and warehousing processes.
Press Fit Assembly
Delivers consistent downward pressure to seat bearings and bushings into housings on high-yield assembly lines.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX20 the Right Cylinder?
Select this 100mm bore actuator when a 63mm bore (providing 1559 N at 0.5 MPa) cannot generate sufficient thrust for your heavy-duty application. The 20mm stroke is optimal for brief, high-impact movements. Because the stroke is well under 300mm, rod-bearing bending is not a concern here.
Ensure you specify the G1/2 port and your desired mounting accessory, such as an FA flange or TC trunnion, when requesting a quote. If your machinery loses air pressure, this standard cylinder cannot hold its load; for fail-safe locking, consider the SAIL or BSAI 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 SAI100AX20 FAQ
At an operating pressure of 0.5 MPa, this 100mm bore cylinder generates 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
Yes. The SAI100X20 is built to the ISO 15552 standard, meaning its mounting dimensions are fully interchangeable with other ISO 15552 profile cylinders, allowing for a direct drop-in replacement.
