About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX20-20S
Its integrated 20mm adjustment screw allows the effective travel to be dialed back from 20mm down to a 0mm stop. This provides exact end-position tuning during commissioning without requiring a physical cylinder swap.
Built with an SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance, this unit includes a magnet (-S) for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel features sensor grooves on both sides, and the G1/2 port handles high flow rates for rapid actuation.

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 SAIJ100AX20-20S Is Used
Precision Pressing
Dial in the exact 0-20mm contact distance for short-stroke pressing operations, ensuring consistent force application without over-travel.
Product Changeover
Quickly adjust the end-stop position during production line changeovers to accommodate varying component heights without changing tooling.
End-Stop Calibration
Perfect for commissioning automated stations where the rear screw fine-tunes the retraction point to align with downstream pick-and-place robots.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX20-20S the Right Cylinder?
The 0-20mm adjustable travel window is ideal for short-stroke clamping or pressing tasks where the exact end-stop must be fine-tuned on the machine. Because the rear adjuster acts only as a travel stop and the air cushion handles deceleration, neither will hold a load without live air; for fail-safe load holding, consider an external rod lock or the SAIL series. To match this ISO 15552 footprint exactly, specify the 100mm bore, 20mm stroke, -20mm adjustment, PT port thread, 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 SAIJ100AX20-20S FAQ
At 0.9 MPa, the push force increases to 7068N.
The rear adjuster screw allows you to shorten the 20mm nominal stroke by up to 20mm, creating a 0-20mm usable travel window. It acts as a mechanical stop for end-position tuning and does not lock the load without live air pressure.
