About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX350-30S
The AirTAC SAIJ100X350-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 320-350 mm. The piston rod utilizes SUS420J2 stainless steel, offering superior corrosion resistance for demanding environments. An integrated magnet enables position sensing with CMSE reed and DMSE electronic switches.
This adjustable-stroke design allows precise end-position tuning at commissioning without swapping the cylinder or adding external stops. The rear adjuster acts strictly as a travel stop and does not hold the load without live air. It uses a G1/2 PT tapered port and 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 SAIJ100AX350-30S Is Used
Machine Changeover
Dial in the 320-350mm travel window during product size changes on a packaging line without replacing the cylinder.
End-Stop Calibration
Fine-tune the retract end position during commissioning to perfect a pressing or forming operation.
Variable Diverter
Adjust the stroke length on a sorting diverter to handle varying package sizes on the fly.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX350-30S the Right Cylinder?
Choose this 100mm bore when an application requires high thrust combined with variable end-stops. If higher force is required, a 125mm bore provides 8590N. Because the 350mm stroke is substantial, an external guide is recommended to prevent excessive side-loading on the SUS420J2 rod.
An adjustable stroke is preferred over a fixed SAI cylinder when you need fine-tuning during machine setup or product changeover. For load-holding without live air pressure, this cylinder is insufficient since the adjuster is only a stop; consider SAIL or BSAI models. To match this ISO 15552 replacement, verify the 100mm bore, 350mm stroke, 30mm adjustment, PT G1/2 port, and -S magnet.
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 SAIJ100AX350-30S FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 30mm, creating a 320-350mm travel window. It acts as a mechanical stop and does not lock or hold the load without continuous air pressure.
