About the Airtac SAI100 Standard Air Cylinder SAI100X240
The AirTAC SAI100X240 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. 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 moving substantial loads over its 240 mm stroke. The extruded aluminum barrel design omits tie rods, ensuring a clean exterior that resists mechanical interference.
This specific configuration utilizes a standard carbon steel piston rod and PT tapered port threads. Because it lacks the -S magnet suffix, external position sensing relies on mechanical limit switches rather than the integrated sensor grooves. For applications requiring integrated pneumatic control, the SAIF variant combines this bore size with a built-in 4M solenoid valve.

Where the Airtac SAI100 Standard Air Cylinder SAI100X240 Is Used
Heavy Stamping
Provides the necessary 3927 N of push force at 0.5 MPa to actuate large mechanical presses and form rigid metal components.
Pallet Diversion
Uses the 240 mm stroke to push heavy loaded pallets smoothly onto secondary packaging lines without tie-rod obstruction.
Mold Clamping
Secures substantial injection molds during processing, utilizing the robust carbon steel rod to handle high tensile and compressive stresses.
Is the Airtac SAI100 Standard Air Cylinder SAI100X240 the Right Cylinder?
Selecting this 100 mm bore is ideal when the 80 mm class (2513 N push at 0.5 MPa) is insufficient for your payload, but the massive 125 mm bore is unnecessary. The 240 mm stroke falls below the 300 mm side-load threshold, though utilizing the FA or FB flange mounts will optimize load distribution. As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for any standard cylinder sharing these exact mounting dimensions.
Remember that the adjustable air cushions at both ends only decelerate the piston near stroke end; they do not hold the load in place. If air pressure is lost, the rod will drift. For vertical loads requiring fail-safe holding, consider the SAIL variant with its air-released lock or an external pilot-operated check valve.
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 SAI100X240 FAQ
At an operating pressure of 0.5 MPa, this double-acting cylinder generates a push force of 3927 N and a pull force of 3681 N. If pressure increases to 0.7 MPa, the push force rises to 5497 N.
Yes, the SAI100X240 is dimensionally interchangeable per ISO 15552. You can swap it directly with other ISO 15552 profile cylinders that share the same 100 mm bore, 240 mm stroke, and mounting interface, provided your system uses PT port threads.
