About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX290-100
The AirTAC SAIJ100X290-100 is a double-acting ISO 15552 profile cylinder featuring a rear mechanical adjuster that permits a usable travel window of 190 to 290 mm. The extruded aluminum barrel includes sensor grooves on both sides for straightforward position feedback integration.
This unit utilizes a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and features PT tapered port threading. The rear stopper screw allows you to fine-tune the retract end position at commissioning without adding external stops or changing the cylinder body.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
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 SAIJ100AX290-100 Is Used
Product Changeover
Quickly dial the stroke back from 290 mm down to 190 mm to accommodate varying package sizes on a packaging line without changing hardware.
End-Position Tuning
Fine-tune the retract stop during machine commissioning to achieve exact positioning, compensating for mechanical tolerances in the fixture.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX290-100 the Right Cylinder?
The 100 mm adjustment range is selected when machinery requires significant product-size changeovers, allowing the stroke to be dialed back up to 100 mm rather than swapping a fixed SAI cylinder. For true load-holding without live air pressure, note that this adjuster acts only as a travel stop; you would need an external rod lock or a related SAIL pneumatic lock cylinder.
Because the nominal stroke is 290 mm, ensure adequate external guiding to prevent excessive rod side-loading, as even the robust 25 mm rod diameter cannot support high lateral forces unsupported. This cylinder is dimensionally interchangeable per ISO 15552 and uses the standard SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ100AX290-100 FAQ
At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster acts as a mechanical stop, allowing you to shorten the effective stroke by up to 100 mm. This creates a usable travel window of 190 to 290 mm. It is a stop, not a lock, and requires live air to hold the load.
