About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX180-100
The AirTAC SAIJ80X180-100 is a double-acting ISO 15552 profile cylinder featuring an integrated rear stroke adjuster. It provides a usable travel window of 80 to 180 mm, enabling precise end-position tuning without swapping out the entire unit.
This variant utilizes a SUS420J2 stainless steel rod for superior corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, allowing for direct mounting of position switches. The rear adjustment mechanism acts purely as a travel stop to set the retract distance, meaning it cannot hold a load in place without continuous live air pressure.

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 SAIJ80AX180-100 Is Used
Product Changeover
Quickly dial back the retract stroke from 180 mm down to 80 mm when switching to a shorter product format on the line.
End-Stop Calibration
Fine-tune the final resting position during machine commissioning to achieve exact clamping or pressing distances.
Variable Positioning
Set intermediate travel distances on packaging equipment without needing to halt production to install physical spacers.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX180-100 the Right Cylinder?
Selecting this 80 mm bore model makes sense when a machine requires a 2268 N pull force at 0.5 MPa but faces frequent product size changeovers. If your application demands less force, stepping down to a 63 mm bore yields 1402 N of pull, whereas moving up to a 100 mm bore provides 3681 N. The massive 100 mm adjustment range allows operators to dial in the retract stroke perfectly during commissioning rather than machining custom external stops.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 180 mm nominal stroke, 100 mm adjustment, PT port threads, and the specific mounting accessory. SAIJ supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, but omits FB, CA, CB, and CR brackets. Because the nominal stroke is 180 mm, side-load risks remain low, though any unsupported load should still use an external guide. For load-holding without air pressure, consider the SAIL or BSAI series 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 SAIJ80 Adjustable Cylinder SAIJ80AX180-100 FAQ
The maximum operating pressure is 1.0 MPa.
The rear adjuster screw acts as a mechanical stop that shortens the retract travel. For this model, it creates a usable stroke window between 80 mm and 180 mm, allowing precise end-position tuning without replacing the cylinder.
