About the Airtac SAI100 Standard Air Cylinder SAI100AX125
The AirTAC SAI100X125 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It provides a substantial push force of 5497 N at 0.7 MPa across its 125 mm stroke. This standard stroke length is optimal for mid-range material handling and robust clamping tasks.
Beyond the core specifications, this configuration features a SUS420J2 stainless steel piston rod (option A) for excellent corrosion resistance in humid industrial environments. The extruded aluminum barrel includes dual sensor grooves, allowing direct mounting of CMSE or DMSE switches when a magnet is specified, while the PT tapered ports ensure a tight, leak-free pneumatic connection.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX125 Is Used
Heavy-Duty Stamping
Provides the necessary 7068 N output at 0.9 MPa to actuate heavy stamping and forming presses reliably.
Pallet Diverting
Ideal for high-mass pallet diverting gates where a 125 mm stroke quickly redirects heavy goods on conveyor lines.
Robotic Grippers
Drives large-scale robotic gripper assemblies requiring substantial clamping force to secure bulky components.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX125 the Right Cylinder?
Selecting this 100 mm bore makes sense when the 80 mm variant's 3518 N at 0.5 MPa is insufficient for your load, but you want to avoid the heavier 125 mm frame. Its 125 mm stroke offers ample travel without the side-load complications of longer extensions.
As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for any standard ISO 15552 unit using identical mounting dimensions. Remember that a standard double-acting cylinder relies on continuous air pressure to hold position; if your application requires static load holding upon air loss, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants instead.
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 SAI100AX125 FAQ
At 0.7 MPa operating pressure, this 100 mm bore cylinder generates 5497 N of push force and 3681 N of pull force. At its maximum 1.0 MPa pressure, the theoretical push force reaches 801 kgf.
Yes, the SAI100X125 is dimensionally interchangeable per ISO 15552 standards. It shares the exact mounting interface and G1/2 PT port locations of other ISO 15552 profile cylinders, allowing a seamless drop-in replacement.
