About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX290-20
The AirTAC SAIJ100X290-20 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 270-290 mm usable travel window, allowing you to dial back the nominal 290 mm stroke by up to 20 mm during commissioning without adding external stops.
This SKU features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and uses a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides, while the adjustable stopper and air cushions manage end-of-stroke deceleration. Note that the adjuster acts as a travel stop, not a load-holding lock.

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 SAIJ100AX290-20 Is Used
Tooling Changeovers
Fine-tune the 270-290 mm end position rapidly when swapping out machining fixtures or adapting the line for a new part family.
Variable End Stops
Adjust the retract stop on the fly to accommodate different package sizes or product lengths without physically replacing the actuator.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX290-20 the Right Cylinder?
Choose this 100 mm bore when a 63 mm bore (1402 N pull at 0.5 MPa) lacks the force needed for heavier tooling, but a 125 mm unit would be physically oversized. The 20 mm rear adjustment screw is ideal for product changeovers, letting you fine-tune the exact end position in seconds. Because the nominal 290 mm stroke exceeds 300 mm when combined with the rod length, an external guide rail is recommended to prevent excessive side-loading on the rod.
For a direct ISO 15552 replacement, match the 100 mm bore, 290 mm stroke, 20 mm adjustment range, PT port thread, and SUS420J2 rod material. SAIJ uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. If your application requires the load to stay held without continuous air pressure, select a SAIL or BSAI cylinder instead.
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 SAIJ100AX290-20 FAQ
A rear-mounted stopper screw lets you trim the effective travel by up to 20 mm, creating a 270-290 mm usable window. It allows fine-tuning of the end position at commissioning without swapping the cylinder.
The maximum push force is 7068 N at 0.9 MPa.
