About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX325-10
The AirTAC SAIJ100X325-10 is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. The integrated stopper allows you to trim the effective travel back by up to 10mm, creating a precise 315-325mm usable stroke window for fine-tuning end positions during commissioning. This cylinder features a SUS420J2 stainless steel rod and PT tapered port threads.
Unlike fixed-stroke alternatives, this adjustable model lets you dial in the retract end-position without swapping the barrel or adding external stops. The rear adjuster acts purely as a travel stop to set deceleration and cannot hold a load without live air pressure. It supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.

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 SAIJ100AX325-10 Is Used
Machine Setup Calibration
Fine-tune the 315-325mm travel window during initial commissioning to perfectly align heavy press fixtures without machining custom spacers.
Product Changeover Stops
Adjust the retract end-position by up to 10mm on packaging lines to accommodate varying package lengths quickly and efficiently.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX325-10 the Right Cylinder?
Choose this 100mm bore cylinder when your application requires heavy thrust (up to 3927N at 0.5MPa) alongside minor end-position corrections. Because the nominal stroke is 325mm, an external guide is recommended to prevent excessive side-loading on the 25mm rod and M20x1.5 rod thread, ensuring long seal life.
Select the adjustable SAIJ over a fixed SAI when you need a variable end-stop for product changeovers or machine setup flexibility. For load-holding without continuous air pressure, this cylinder is insufficient; the rear adjuster is a stop, not a lock. In such cases, consider an AirTAC SAIL (air-released lock) or BSAI (clamp-lock) cylinder instead.

- ✓ 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 SAIJ100AX325-10 FAQ
At the maximum 1.0MPa pressure, it can deliver up to 801kgf.
A rear external screw acts as a mechanical stop, allowing you to shorten the 325mm nominal stroke by up to 10mm, resulting in a usable travel range of 315-325mm. This adjuster sets the travel end but does not lock the load without live air pressure.
