About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX425-30
The AirTAC SAIJ100X425-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 395 to 425 mm usable travel window, allowing you to dial back the nominal 425 mm stroke by up to 30 mm during commissioning.
Unlike a fixed-stroke SAI, this model lets you fine-tune the retract end position without swapping hardware or adding external stops. The 25 mm rod uses a SUS420J2 stainless steel material (code A) for better corrosion resistance, and the extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.

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 SAIJ100AX425-30 Is Used
Product Changeover
Dial in the exact retract position within the 395-425 mm window during packaging line format changes without swapping out the cylinder.
Machine Setup
Fine-tune the end-stop during initial commissioning to compensate for mechanical tolerances and achieve precise positioning of heavy actuators.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX425-30 the Right Cylinder?
Choose this 100 mm bore when a 63 mm bore (1402 N pull at 0.5 MPa) is insufficient for your load, but you want to avoid the larger 80 mm option. The adjustable 30 mm window is ideal for product changeovers where the exact retract position varies slightly. Because the stroke is 425 mm, an external guide is recommended to manage side loads on the 25 mm rod over this extended travel.
Remember that the rear adjuster acts as a travel stop, not a lock; it cannot hold a load without live air pressure. For true load-holding without continuous air, select the SAIL or BSAI series. To replace an ISO 15552 cylinder, match the 100 mm bore, 425 mm stroke, 30 mm adjustment, PT port, and your chosen mounting from the SAIJ set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
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 SAIJ100AX425-30 FAQ
A rear adjusting screw lets you shorten the effective stroke by up to 30 mm, providing a usable travel window of 395 to 425 mm. This allows fine-tuning of the end position at commissioning without adding external stops.
At 0.9 MPa, the push force increases to 7068 N.
