About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX20-10S
It features a SUS420J2 stainless steel rod and a PT tapered port. By integrating a rear stopper screw, this model allows you to dial back the nominal 20mm stroke by up to 10mm, creating a precise 10-20mm usable travel window for exact end-position tuning.
Because it is a profile cylinder with an extruded aluminum barrel, it includes sensor grooves on both sides. The integrated magnet (-S) supports AirTAC CMSE reed and DMSE electronic solid-state switches for exact position feedback. The rear adjuster acts purely as a travel stop to set the retraction end, meaning it cannot hold the load without live air pressure.

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 SAIJ100AX20-10S Is Used
Short-Stroke Clamping
Ideal for high-force clamping tasks where the 10-20mm adjustable travel window allows operators to dial in the exact grip position on varying part thicknesses.
Commissioning Calibration
The rear stopper screw lets maintenance teams fine-tune the retraction end-point during initial machine setup without machining external stop blocks.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX20-10S the Right Cylinder?
The adjustable-stroke design is ideal for machine setups requiring fine-tuning of the end-stop during commissioning without swapping cylinders or adding external stops. For load-holding without continuous air pressure, consider an external rod lock or pilot-operated check valve, or explore the SAIL or BSAI series.
To match this exact configuration for an ISO 15552 replacement, specify a 100mm bore, 20mm stroke, 10mm adjustment, PT ports, and a magnet for CMSE/DMSE sensors. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. Since the stroke is only 20mm, external side-load guides are less critical than on longer strokes, but the robust 25mm rod still handles lateral forces well.
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 SAIJ100AX20-10S FAQ
At 0.7MPa, the push force increases to 5497N.
The rear adjuster screw allows you to shorten the 20mm nominal stroke by up to 10mm, providing a usable travel window of 10-20mm. This stopper sets the end position but does not lock the load without live air pressure.
