About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX150-40
The AirTAC SAIJ80X150-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 150 mm nominal travel by up to 40 mm. This creates a 110-150 mm usable window for fine-tuning the retract end position during commissioning without adding external stops.
This variant features a SUS420J2 stainless steel rod (option A) for improved corrosion resistance compared to standard carbon steel. The PT tapered port threads ensure a tight, reliable air connection, while the extruded aluminum barrel integrates sensor grooves on both sides for flexible switch mounting.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 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 SAIJ80 Adjustable Cylinder SAIJ80AX150-40 Is Used
Machine Setup Tuning
Dial in the exact 110-150 mm retract position during initial commissioning to perfect a pressing or clamping operation without machining external spacers.
Product Changeover
Quickly adjust the end stop for different product sizes on the same line, using the 40 mm trim window to accommodate varying part heights.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX150-40 the Right Cylinder?
The adjustable 110-150 mm travel window is ideal for product changeovers where the exact end position varies slightly. For any application requiring a stroke of 300 mm or more on this bore, adding an external guide is recommended to support the rod against side loads.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 150 mm stroke, 40 mm adjustment, PT G3/8 port, and desired mounting from the SAIJ set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for fail-safe load holding, consider the SAIL or BSAI series.
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 SAIJ80 Adjustable Cylinder SAIJ80AX150-40 FAQ
At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster screw lets you shorten the 150 mm nominal stroke by up to 40 mm, creating a 110-150 mm travel window. It functions purely as a mechanical stop to set the end position and does not lock or hold the load without continuous air pressure.
