About the Airtac SAI100 Standard Air Cylinder SAI100AX115
The AirTAC SAI100X115 is a double-acting ISO 15552 profile cylinder featuring a 100mm bore and a 115mm stroke. It supplies a robust 3927 N of push force at 0.5 MPa, making it well-suited for heavy-duty industrial handling tasks.
This genuine AirTAC unit is equipped with an SUS420J2 stainless steel piston rod for superior corrosion resistance. It utilizes PT tapered port threads and includes adjustable air cushions at both ends to dampen impact. Note that sensors like CMSE or DMSE require a magnet, which is absent on this non-S configuration.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX115 Is Used
Heavy Machinery Clamping
Ideal for securing large metal workpieces during machining, utilizing its 3927 N push force to prevent movement under heavy cutting loads.
Pallet Lifting
Provides the vertical lifting power required to elevate loaded pallets in automated distribution centers and packaging lines.
Press Ejection
Exerts reliable force to eject finished parts from heavy-duty stamping presses, ensuring smooth production cycle times.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX115 the Right Cylinder?
Select this 100mm bore when an 80mm bore (2513 N push at 0.5 MPa) lacks the necessary thrust for moving heavy pallets or lifting substantial mechanical assemblies. The 115mm stroke provides a moderate extension length that avoids the severe side-load bending risks seen in longer 300mm-plus rods.
As a standard double-acting cylinder, the SAI100X115 relies entirely on live air pressure to maintain its position. If your application requires the load to be held securely during a pressure drop or valve centering, you must integrate an external pilot-operated check valve or transition to the SAIL (air-released lock) variant. Being dimensionally interchangeable per ISO 15552, it serves as a drop-in replacement for other ISO 15552 profile cylinders using the same PT 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.
