About the Airtac SAI100 Standard Air Cylinder SAI100X290
The AirTAC SAI100X290 is a double-acting ISO 15552 profile cylinder featuring a 100mm bore and 290mm stroke. It delivers a robust push force of 3927 N at 0.5 MPa, extending to 7068 N at 0.9 MPa, making it well-suited for heavy-duty positioning tasks.
This extruded aluminum barrel design incorporates sensor grooves on both sides for flexible CMSE or DMSE switch mounting. The standard carbon steel piston rod ensures high tensile strength, while the adjustable air cushions at both ends manage impact deceleration effectively.

Where the Airtac SAI100 Standard Air Cylinder SAI100X290 Is Used
Automotive Body Welding
Provides the 3927 N push force at 0.5 MPa required to clamp heavy chassis panels securely during robotic spot welding operations.
Pallet Load Stopper
Acts as a robust high-mass stop gate on heavy-duty package conveyors, utilizing its 290mm stroke to clear passing pallets when retracted.
Injection Mold Ejection
Drives heavy mold ejection plates with precise 290mm travel, relying on adjustable end cushions to protect expensive tooling from impact damage.
Is the Airtac SAI100 Standard Air Cylinder SAI100X290 the Right Cylinder?
If your application requires slightly less thrust, stepping down to the 80mm bore yields 2513 N at 0.5 MPa, whereas moving up to the 125mm bore provides 6136 N for heavier loads. Because this 290mm stroke exceeds 250mm, avoid side loading to prevent rod-bearing bending; utilize an external guide rail or a guided cylinder for optimal stability.
This model is dimensionally interchangeable per ISO 15552 standards, ensuring a seamless drop-in replacement for other ISO 15552 profile cylinders. To match your setup, specify the G1/2 PT port, appropriate mounting accessories like FA flanges, and add the -S magnet option if position sensing is required. Note that this standard cylinder does not hold loads upon air loss; for failsafe holding, consider the SAIL or BSAI variants.
Quick checklist
- ✓ Required force at your working pressure

- ✓ 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.
