About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX290-40
The AirTAC SAIJ100X290-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 250-290 mm usable travel window, allowing you to dial back the 290 mm nominal stroke by up to 40 mm without adding external stops.
This SKU uses a SUS420J2 stainless steel rod for corrosion resistance and pairs self-centering variable air cushions at both ends with the external stopper to manage end-of-travel deceleration. The extruded aluminum barrel includes sensor grooves on both sides for fitting CMSE reed or DMSE electronic switches if a magnet is added later. Mounting options cover Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ100AX290-40 Is Used
Machine Changeover
Dial the end position back by up to 40 mm during product size transitions without physically swapping the cylinder or reworking the fixture.
End-Stop Tuning
Fine-tune the final 250-290 mm travel window at commissioning to perfect a pressing or clamping operation.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX290-40 the Right Cylinder?
The 40 mm adjustment range is ideal for product changeovers where the exact end-of-stroke position must be fine-tuned on the machine. Because the 290 mm stroke is substantial, an external guide is recommended to prevent excessive side-loading on the 25 mm rod.
The rear screw acts solely as a travel stop and does not hold the load without live air pressure; for fail-safe load holding, select an SAIL or BSAI cylinder. For a direct ISO 15552 replacement, match the 100 mm bore, 290 mm stroke, 40 mm adjuster, PT tapered port threads, and standard mounting set.
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 SAIJ100AX290-40 FAQ
A rear external stopper screw lets you shorten the 290 mm nominal stroke by up to 40 mm, creating a 250-290 mm usable travel window. It acts as a mechanical stop and does not lock the load without continuous air pressure.
