About the Airtac SAI100 Standard Air Cylinder SAI100BX425S
The AirTAC SAI100X425-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty handling. It provides a robust push force of 3927 N at 0.5 MPa and 5497 N at 0.7 MPa, making it well-suited for high-load automation tasks requiring a 425 mm stroke. The extruded aluminum barrel omits traditional tie rods while maintaining strict standardized mounting dimensions.
Configured with a SUS304 stainless steel rod (option B) and a magnet for sensors, this variant integrates seamlessly with CMSE and DMSE reed switches via the dual side grooves. Fluid ports feature PT tapered threading, and the standard adjustable air cushions at both ends ensure smooth deceleration of dynamic loads.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX425S Is Used
Automotive Body Welding
Handles heavy clamping and positioning of vehicle panels with 5497 N of thrust at 0.7 MPa, while the SUS304 rod resists corrosive shop environments.
Pallet Transfer Systems
Executes 425 mm strokes to push heavy loaded pallets between conveyor lines, relying on adjustable cushions to stop high-mass movements smoothly.
Injection Mold Ejection
Provides reliable pulling and pushing forces for heavy mold ejection plates, utilizing the integrated magnet for precise end-of-stroke confirmation via DMSE sensors.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX425S the Right Cylinder?
When specifying this 100 mm bore actuator, verify if the 5497 N thrust at 0.7 MPa is sufficient, or if stepping down to an 80 mm bore (yielding 3518 N) better optimizes air consumption. For this 425 mm stroke, long unsupported rods are susceptible to bending under side loads; utilizing an external guide rail or a guided cylinder is strongly recommended to prevent rod-bearing damage.
This model serves as a drop-in replacement for any ISO 15552 cylinder matching the 100 mm bore, 425 mm stroke, G1/2 port, and standard mounting accessory footprint (such as FA flange or TC trunnion). If the application requires holding a load during air loss, note that the air cushion only decelerates the piston and does not act as a brake; consider the SAIL or BSAI locking variants for fail-safe 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 SAI100BX425S FAQ
At 0.7 MPa operating pressure, the push force is 5497 N and the pull force is 3681 N. At 0.5 MPa, it delivers 3927 N push and 3681 N pull.
Yes, the SAI100X425-S is a genuine ISO 15552 profile cylinder, making it dimensionally interchangeable with other ISO 15552 cylinders of the same bore and stroke, provided the G1/2 port and mounting interface match.
