About the Airtac SAI100 Standard Air Cylinder SAI100X280S
The AirTAC SAI100X280-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It provides a robust 3927 N push force at 0.5 MPa and 5497 N at 0.7 MPa, making the 280 mm stroke well-suited for moving substantial loads through machining or packaging cycles.
This configuration features a standard carbon steel piston rod and a built-in magnet for direct compatibility with CMSE and DMSE sensor switches along the dual barrel grooves. The extruded aluminum profile design omits tie-rods, offering a clean exterior that drops seamlessly into existing ISO 15552 mounting footprints.

Where the Airtac SAI100 Standard Air Cylinder SAI100X280S Is Used
Heavy Machining Clamps
Secures large metal castings during CNC milling operations, utilizing the 5497 N push force at 0.7 MPa to prevent workpiece shifting under aggressive cutting forces.
Pallet Diverters
Pushes heavy loaded pallets across transfer lines over the 280 mm stroke, relying on the adjustable air cushions to bring high-mass loads to a smooth stop.
Press Ejection
Ejects formed parts from hydraulic presses, where the robust carbon steel rod withstands repetitive high-impact contact and the dual sensor grooves provide precise positioning feedback.
Is the Airtac SAI100 Standard Air Cylinder SAI100X280S the Right Cylinder?
Select this 100 mm bore when a 80 mm cylinder (2513 N at 0.5 MPa) lacks the necessary thrust, but a 125 mm unit would be physically oversized. The G1/2 PT port ensures high airflow to maintain the 30-800 mm/s speed range across the 280 mm extension.
Because this stroke exceeds 300 mm, avoid relying on the piston rod to absorb side loads; long unsupported rods are prone to bending under lateral stress. Implement an external guide rail or use a guided cylinder to protect the rod bearing. Note that standard air cushions only decelerate the piston at stroke ends and will not hold a load vertically if air pressure drops; for position holding, specify a SAIL or BSAI variant.
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 SAI100X280S FAQ
At a standard operating pressure of 0.7 MPa, this 100 mm bore cylinder generates a push force of 5497 N and a pull force of 3681 N. At 0.5 MPa, the push force is 3927 N.
Yes, the SAI100X280-S is dimensionally interchangeable per ISO 15552. Its profile barrel and mounting dimensions allow it to serve as a drop-in replacement for other ISO 15552 standard cylinders with matching 100 mm bore and 280 mm stroke specifications.
