About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX170-50S
The AirTAC SAIJ80X170-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 120-170 mm usable travel window from its 170 mm nominal stroke. The -S magnet enables position sensing with AirTAC CMSE reed and DMSE electronic switches.
This model features a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and uses PT tapered port threads. The external rear stopper allows fine end-position tuning during commissioning without adding external stops. The adjuster acts strictly as a travel stop and does not hold the load without 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 SAIJ80AX170-50S Is Used
Machine Setup Tuning
Dial in the exact end position during commissioning using the 50 mm adjustment window, avoiding the need to machine custom external spacers.
Product Changeover
Quickly adapt the 170 mm stroke for different package sizes on a packaging line by retracting the stopper up to 50 mm.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX170-50S the Right Cylinder?
The 50 mm adjustment range is ideal for product changeovers on a production line, letting you dial back the 170 mm stroke by up to 50 mm without swapping the cylinder. For fixed-stroke needs without a stopper, use the standard SAI cylinder.
This cylinder uses PT ports and supports mounting options Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the 170 mm stroke is under the 300 mm side-load threshold, the 25 mm rod and M20x1.5 thread handle standard loads well, though external guides are recommended for heavy lateral loads. If you need true load-holding without live air, 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 SAIJ80AX170-50S FAQ
At the maximum 1.0 MPa pressure, it delivers up to 513 kgf.
The rear adjuster screw lets you shorten the 170 mm nominal stroke by up to 50 mm, creating a 120-170 mm travel window. It acts as a travel stop and does not lock the position without live air.
