About the Airtac SAI100 Standard Air Cylinder SAI100AX40
The AirTAC SAI100X40 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty handling. It provides a robust push force of 3927 N and a pull force of 3681 N at 0.5 MPa, making it well-suited for short 40 mm clamping and pressing operations.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance. It utilizes PT tapered port threads (G1/2) and, because a magnet is not specified, it operates without integrated position sensing.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX40 Is Used
Heavy-Duty Stamping
Generates 3927 N of push force at 0.5 MPa for short-stroke metal stamping and forming tasks.
Industrial Clamping
Provides rigid 40 mm clamping action to secure heavy workpieces during machining or welding processes.
Pallet Halting
Acts as a robust stopper mechanism on high-mass conveyor lines, utilizing its 513 kgf maximum theoretical force.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX40 the Right Cylinder?
Select this 100 mm bore when a 63 mm bore (offering 1559 N push at 0.5 MPa) cannot generate enough thrust for your tooling. Conversely, if your application requires even greater power, stepping up to a 125 mm bore yields 6136 N. The 40 mm stroke is highly compact, keeping the retracted length short and minimizing rod-bearing bending stresses.
As a standard double-acting actuator, this cylinder relies on continuous air pressure to maintain its position and will drift if pressure is lost. For applications requiring pneumatic locking, consider the SAIL or BSAI variants. Being dimensionally interchangeable per ISO 15552, it serves as a direct drop-in replacement for other ISO 15552 profile cylinders, matching the standard G1/2 port and 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.
