About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX700-20S
The AirTAC SAIJ100X700-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the retract end position. With a 700 mm nominal stroke and a 20 mm adjustment range, it provides a usable travel window of 680-700 mm for precise machine setup without needing external stops.
This variant is equipped with a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel features sensor grooves on both sides, and the G1/2 port ensures adequate airflow for its 30-800 mm/s operating 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 SAIJ100AX700-20S Is Used
Product Size Changeovers
Dial in the 680-700 mm retract position during format changes on packaging lines without swapping out the entire actuator.
End-Stop Calibration
Fine-tune the final end position during machine commissioning to avoid mechanical crashes and optimize tooling alignment.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX700-20S the Right Cylinder?
The adjustable stroke is ideal for product changeovers on a line, letting you dial in the exact 680-700 mm end-stop at commissioning rather than swapping cylinders. Because the stroke is 700 mm, the M20x1.5 rod needs external guiding to prevent excessive side-loading on the seals.
This SAIJ model uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. The rear adjuster acts purely as a travel stop to set deceleration; it is not a lock. If your application requires the load to be held without live air pressure, use an external rod lock or pilot-operated check valve. For a dimensionally interchangeable ISO 15552 replacement, match the 100 mm bore, 700 mm stroke, 20 mm adjustment, PT tapered ports, 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 SAIJ100AX700-20S FAQ
At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster screw allows you to shorten the effective stroke by up to 20 mm, creating a 680-700 mm travel window. It acts as a mechanical stop and does not lock the load without live air.
