About the Airtac SAI100 Standard Air Cylinder SAI100AX120S
The AirTAC SAI100X120-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 3927 N of push force at 0.5 MPa, this 100mm bore unit is built to handle substantial loads across its 120mm stroke. The extruded aluminum barrel omits traditional tie-rods, providing a smooth exterior that simplifies cleaning and sensor mounting.
Equipped with a -S magnet, this model operates seamlessly with CMSE and DMSE reed switches housed in the dual side sensor grooves. It features a SUS420J2 stainless steel piston rod (material code A) for enhanced resistance against corrosion and surface wear. Fluid compatibility requires air filtered to 40 um, operating safely between -20 and +70 C.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX120S Is Used
Heavy-Duty Stamping
Provides the necessary 3927 N output force at 0.5 MPa to execute short-stroke metal stamping and forming operations securely.
Automotive Component Clamping
Holds heavy automotive castings firmly in place during machining, utilizing the SUS420J2 rod to withstand harsh industrial environments.
Pallet Dispensing
Actuates robust pallet handling mechanisms where high push force is required to index heavy loads smoothly and reliably.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX120S the Right Cylinder?
Selecting this 100mm bore cylinder is ideal when an application demands nearly 4000 N of thrust at 0.5 MPa but does not require the full 1500mm standard stroke capacity, making the 120mm travel optimal for compact, high-force clamping or pressing. If your setup requires less force, stepping down to an 80mm bore yields 2513 N at 0.5 MPa, conserving valuable air volume and physical footprint.
Because the 120mm stroke is well below the 300mm threshold, side-load stress on the rod bearing remains minimal. To ensure a seamless drop-in replacement, verify the ISO 15552 mounting dimensions, the G1/2 port size, and your required accessory type—such as an FA flange or TC trunnion. Remember that the adjustable air cushions at both ends only decelerate the piston; they do not lock the load. If pressure is lost, the rod will drift, requiring an external check valve or a SAIL variant for true position holding.
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 SAI100AX120S FAQ
At a standard operating pressure of 0.5 MPa, this 100mm bore cylinder generates 3927 N of push force and 3681 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 5497 N.
Yes, the SAI100X120-S is dimensionally interchangeable per ISO 15552 standards. You can use it as a drop-in replacement for other ISO 15552 profile cylinders, provided your port size and mounting dimensions align.
