About the Airtac SAI100 Standard Air Cylinder SAI100AX300S
The AirTAC SAI100X300-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It delivers a robust 5497 N push force at 0.7 MPa across its 300 mm stroke. The extruded aluminum barrel design omits tie rods, providing a clean exterior that is dimensionally interchangeable with other ISO 15552 cylinders.
This specific configuration includes an -S magnet for direct mounting of CMSE or DMSE reed switches along the dual sensor grooves. The piston rod utilizes SUS420J2 stainless steel (material code A) for superior corrosion resistance, and the PT tapered port threads ensure a reliable, leak-free pneumatic connection.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX300S Is Used
Heavy-Duty Stamping
Applies 5497 N of force at 0.7 MPa to securely form and stamp thick metal components.
Pallet Diverting
Utilizes the 300 mm stroke to push heavy pallets across high-throughput packaging conveyors.
Automated Pressing
Maintains precise pressing force for assembling industrial bearings and heavy bushings.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX300S the Right Cylinder?
Providing 3927 N of thrust at 0.5 MPa, this 100 mm bore unit is ideal for high-force pressing and heavy lifting. If your application requires less force, stepping down to the 80 mm bore yields 2513 N at 0.5 MPa while saving space. Conversely, moving up to the 125 mm bore offers 6136 N at 0.5 MPa for extreme loads.
Because this model features a 300 mm stroke, the unsupported rod is highly susceptible to bending under side loads. To prevent premature rod-bearing wear, implement an external guide rail or use a fully guided cylinder. Note that the adjustable air cushions only decelerate the piston at stroke ends; they do not hold the load. If pneumatic pressure is lost, the rod will drift. For fail-safe position holding, integrate the SAIL locking variant or an external rod lock.
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 SAI100AX300S FAQ
At an operating pressure of 0.7 MPa, this 100 mm bore cylinder generates 5497 N of push force and 3681 N of pull force. It can safely operate up to 1.0 MPa.
No, the standard SAI cylinder uses adjustable air cushions for end-of-stroke deceleration only, not for locking. If your application requires vertical load holding without live pressure, use the SAIL air-released lock variant or an external rod lock.
