About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX70-10S
The AirTAC SAIJ100X70-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling you to fine-tune the retract end-position during commissioning. It provides a usable travel window of 60-70 mm by allowing up to 10 mm of trim from the 70 mm nominal stroke.
This variant features a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance, PT tapered ports, and a position magnet for CMSE or DMSE sensors. The extruded aluminum barrel includes sensor grooves on both sides, and it supports a mounting subset of 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 SAIJ100AX70-10S Is Used
Machine Changeover
Dial in the 60-70 mm travel window during product size changeovers without swapping out the entire cylinder assembly.
End-Position Tuning
Fine-tune the retract stop during commissioning to absorb mechanical tolerances and achieve precise final positioning.
Variable End Stops
Set custom retract distances on automated lines using the rear stopper screw while maintaining high thrust output.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX70-10S the Right Cylinder?
The 10 mm adjustment range is ideal for product changeovers, letting you dial in the exact end-stop without swapping the cylinder or adding external stops. Remember that the rear adjuster acts only as a travel stop; it does not hold the load without live air. For true load-holding, consider an external rod lock or the SAIL/BSAI series. To match this ISO 15552 replacement exactly, specify: 100 mm bore, 70 mm stroke, 10 mm adjustment, PT ports, and the -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 SAIJ100AX70-10S FAQ
The rear adjuster screw lets you shorten the 70 mm nominal stroke by up to 10 mm, creating a 60-70 mm usable travel window. The adjuster is a mechanical stop for end-position tuning, not a lock, and it requires live air to hold the load.
