About the Airtac SAI100 Standard Air Cylinder SAI100BX325S
The AirTAC SAI100X325-S is a double-acting ISO 15552 profile cylinder featuring a 100mm bore and a 325mm stroke. It generates a robust 3927 N of push force at 0.5 MPa, extending to 7068 N at 0.9 MPa, making it well-suited for moving heavy payloads across mid-to-long travel distances.
This specific configuration includes a SUS304 stainless steel piston rod for superior corrosion resistance in harsh environments. It is equipped with a magnet for direct compatibility with CMSE and DMSE series sensor switches, which seat neatly into the dual extruded grooves on the aluminum barrel.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX325S Is Used
Heavy Stamping Press
Provides the high 3927 N push force required to actuate heavy-duty stamping and forming presses in metal fabrication lines.
Pallet Diversion
Utilizes the 325mm stroke to push heavy pallets across transfer lanes, with the SUS304 rod enduring repetitive industrial wear.
Large Component Lift
Raises substantial automotive or appliance sub-assemblies over a 325mm travel distance, relying on integrated CMSE sensors for position verification.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX325S the Right Cylinder?
Selecting this 100mm bore over the smaller 80mm variant upgrades your thrust from 2513 N to 3927 N at 0.5 MPa, while stepping up further to a 125mm bore yields 6136 N. The G1/2 PT port ensures high airflow to maintain operational speeds within the 30-800 mm/s range. Because this unit features a 325mm stroke, the extended rod is highly susceptible to bending under side loads; integrating an external guide rail or utilizing a guided cylinder body is strongly recommended to prevent premature rod-bearing wear.
As an ISO 15552 profile cylinder, this model serves as a drop-in replacement for any standard ISO 15552 mounting interface. If your machinery requires the load to remain safely suspended after air pressure is removed, note that the standard adjustable air cushions only decelerate the piston at stroke ends and do not act as a locking mechanism; consider the SAIL or BSAI variants for true fail-safe 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 SAI100BX325S FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. If you increase the operating pressure to 0.9 MPa, the push force scales up to 7068 N.
No, the standard SAI cylinder does not hold position upon pressure loss. The adjustable air cushions only decelerate the piston near the stroke ends. For secure load holding without live pressure, use the SAIL (air-released lock) or BSAI (clamp-lock) variants.
