About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX500-100
The AirTAC SAIJ80X500-100 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. With a nominal 500 mm stroke and a 100 mm adjustment range, it provides a usable travel window of 400 to 500 mm.
This unit features a SUS420J2 stainless steel rod (option A) for superior corrosion resistance and a PT tapered port thread for a tight, reliable connection. The extruded aluminum barrel includes dual sensor grooves, though no magnet is installed. The rear stopper allows fine end-position tuning at commissioning without adding external stops, and the cylinder omits FB, CA, CB, and CR mounts, utilizing a reduced SAIJ 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 SAIJ80AX500-100 Is Used
Variable End-Stop Positioning
Dial in the exact retract distance between 400 and 500 mm during machine commissioning to accommodate varying product dimensions without swapping cylinders.
Product Changeover Systems
Quickly adjust the stroke length on packaging or conveying lines when switching between different package sizes, using the rear screw for rapid setup.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX500-100 the Right Cylinder?
The adjustable stroke is selected over a fixed SAI when a machine requires variable end-stops for product changeovers or setup refinement. Because the stroke is 500 mm, an external guide is recommended to prevent excessive side-loading on the 25 mm rod. For any load-holding requirements without live air pressure, note that the rear adjuster acts only as a travel stop, not a lock; consider an AirTAC SAIL or BSAI cylinder instead. Ensure your ISO 15552 replacement matches the 80 mm bore, 500 mm stroke, PT port, and desired mounting accessory.
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 SAIJ80AX500-100 FAQ
The maximum allowable operating pressure is 1.0 MPa.
The rear adjuster acts as an external stopper that lets you shorten the effective stroke by up to 100 mm from the nominal 500 mm, creating a usable travel window of 400 to 500 mm. It is a travel stop, not a lock, and requires live air to hold the load.
