About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX175-20S
The AirTAC SAIJ80X175-20-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. The integrated -S magnet enables position sensing with AirTAC CMSE reed or DMSE electronic switches.
This specific SKU provides a 155-175mm usable travel window, allowing you to trim the 175mm nominal stroke by up to 20mm during commissioning. The rod is constructed from SUS420J2 stainless steel (code A) for enhanced corrosion resistance, and it uses a PT tapered port thread.

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 SAIJ80AX175-20S Is Used
Machine Changeover
Dial in the 155-175mm travel window during product size changes to set precise end positions without swapping hardware.
Variable End Stops
Use the rear adjuster to modify the retract stroke limit on the fly for flexible manufacturing sequences.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX175-20S the Right Cylinder?
The adjustable stroke is ideal for product changeovers, letting you fine-tune the end position without adding external stops or swapping a fixed-stroke SAI cylinder. To match this ISO 15552 replacement exactly, specify the 80mm bore, 175mm stroke, 20mm adjustment, PT G3/8 ports, SUS420J2 rod, and the -S magnet.
Since the nominal stroke is 175mm, the 25mm rod handles moderate side loads well, though any long unsupported travel still requires an external guide. Remember that the rear adjuster acts only as a travel stop; it does not hold the load without live air. For true load-holding without pneumatic pressure, consider an AirTAC SAIL or BSAI cylinder. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ80AX175-20S FAQ
The maximum thrust is 513 kgf at 1.0 MPa.
The rear adjuster screw allows you to shorten the effective stroke by up to 20mm, creating a usable travel window of 155-175mm. This stopper sets the end position but does not lock the load without continuous air pressure.
