About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX280-30
The AirTAC SAIJ100X280-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 280 mm travel to a precise 250-280 mm window. This makes it highly effective for heavy-duty positioning tasks requiring exact end-stop tuning.
The rear adjustment mechanism functions purely as a mechanical stop to fine-tune the travel end, not as a load-holding lock. For operations needing position retention without continuous air pressure, integrating an external pilot-operated check valve or exploring AirTAC SAIL or BSAI series cylinders is necessary. This unit features variable air cushions at both ends to manage deceleration across its 30-800 mm/s speed range.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX280-30 Is Used
Product Changeover
Fine-tune the 250-280 mm travel window during line changeovers to accommodate different product sizes without changing the cylinder.
End-Position Tuning
Dial in the exact retract stop during machine commissioning to perfect operational timing and mechanical positioning.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX280-30 the Right Cylinder?
Conversely, scaling up to a 125 mm bore provides 11045 N for heavier loads.
The adjustable stroke is ideal for machine setup and product changeovers, allowing you to modify the end position without physically swapping the cylinder or adding external stopper blocks. When replacing an ISO 15552 cylinder, match the 100 mm bore, 280 mm stroke, 30 mm adjustment range, PT port threads, and the specific mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the stroke is 280 mm, ensure adequate external guiding to prevent rod side-loading, despite the robust 25 mm rod diameter.
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 SAIJ100 Adjustable Cylinder SAIJ100AX280-30 FAQ
At 0.5 MPa, the push force is 3927 N.
The rear adjuster acts as a mechanical stop, allowing you to shorten the 280 mm stroke by up to 30 mm, creating a usable travel window of 250-280 mm for fine-tuning without swapping the cylinder.
