About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX550-100
The AirTAC SAIJ100X550-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. The integrated rear stopper allows you to dial back the nominal 550mm travel by up to 100mm, creating a precise 450-550mm usable stroke window for exact end-position tuning.
This unit features a SUS420J2 stainless steel rod for enhanced corrosion resistance and utilizes PT tapered port threads. The extruded aluminum barrel includes dual sensor grooves for CMSE reed and DMSE electronic switches, though a magnet is not pre-installed on this configuration. Mounting options include 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 SAIJ100AX550-100 Is Used
Variable End-Stop Tuning
Dial in the exact retract position within the 450-550mm window during machine commissioning without physically swapping out the actuator.
Product Size Changeover
Quickly adapt automated lines to new product lengths by adjusting the rear stopper, saving time during production format changes.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX550-100 the Right Cylinder?
The adjustable stroke is ideal for machine setup and product changeover, allowing you to fine-tune the retract position without swapping the cylinder or adding external stops. Because the nominal 550mm stroke exceeds 300mm, an external guide is recommended to prevent excessive side-loading on the rod.
When replacing an ISO 15552 cylinder, match the 100mm bore, 550mm stroke, 100mm adjustment range, G1/2 port, PT thread, and SUS420J2 rod material. Note that the rear adjuster acts only as a travel stop to decelerate the load; it does not hold the load without live air pressure. For true load-holding without continuous air, consider the SAIL or BSAI series.
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 SAIJ100AX550-100 FAQ
The rear adjusting screw acts as a mechanical stopper that lets you shorten the effective travel from the nominal 550mm down by up to 100mm. This creates a usable 450-550mm stroke window, allowing precise end-position tuning at commissioning without adding external stops.
At 0.9 MPa, the push force increases to 7068N.
