About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX160-40
The AirTAC SAIJ80X160-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a usable travel window of 120 to 160 mm. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
This unit uses an SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance over standard carbon steel. It features a PT tapered port thread and omits the FB, CA, CB, and CR mounting options, utilizing a reduced ISO 15552 mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ80AX160-40 Is Used
Machine Changeover
Dial in the 120-160 mm travel window during product size transitions to set precise retract positions without replacing the actuator.
End-Stop Tuning
Use the 40 mm rear adjustment screw to fine-tune the final end position during initial machine commissioning, avoiding external stopper hardware.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX160-40 the Right Cylinder?
Choose this 80 mm bore adjustable-stroke cylinder when you need to fine-tune the retract end position during commissioning or product changeover without swapping the cylinder or adding external stops. If your application requires less force, stepping down to a 63 mm bore yields 1559 N at 0.5 MPa. The 25 mm rod and M20x1.5 thread handle high side loads well, but any stroke over 300 mm still requires an external guide.
Because the rear adjuster acts as a travel stop and the air cushions only manage deceleration, this cylinder cannot hold a load without live air pressure. For fail-safe load holding, select the SAIL air-released lock or BSAI clamp-lock series instead. This model is dimensionally interchangeable with other ISO 15552 cylinders of the same bore and stroke.
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 SAIJ80AX160-40 FAQ
At 0.9 MPa, the push force increases to 4523 N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the nominal 160 mm stroke by up to 40 mm, providing a usable travel window of 120 to 160 mm. It is a stop, not a lock, so the cylinder cannot hold a load without live air pressure.
