About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX180-30
The AirTAC SAIJ80X180-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 150-180 mm usable travel window.
This adjustable-stroke design allows precise end-position tuning during commissioning without swapping the cylinder or adding external stops. The rear screw acts purely as a travel stop for deceleration, not a load lock, and the extruded aluminum barrel includes 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 SAIJ80BX180-30 Is Used
Product Changeover
Dial in the 150-180 mm stroke window during format changes on packaging lines without bolting on external stops.
End-Position Tuning
Fine-tune the retract end position at machine commissioning to achieve precise mechanical alignment.
Variable End Stops
Accommodate multiple package sizes on a single conveyor diverter by adjusting the rear stopper screw.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX180-30 the Right Cylinder?
Choose this 80 mm bore when an application requires higher thrust than the 50 mm class (982 N at 0.5 MPa) but does not need the full output of a 100 mm cylinder. The 30 mm adjustment window is ideal for product changeovers on a line, allowing variable end-stops without hardware changes. For exact ISO 15552 replacement matching, confirm the 180 mm stroke, 30 mm adjust code, PT port thread, and standard mounting set (Basic, FA, LB, TC, FTC, TCM1, 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 SAIJ80 Adjustable Cylinder SAIJ80BX180-30 FAQ
At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster screw allows you to shorten the 180 mm nominal stroke by up to 30 mm, creating a 150-180 mm travel window. It functions as a mechanical stop for end-position tuning and does not hold the load without live air pressure.
