About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX165-100S
The AirTAC SAIJ80X165-100-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. Because this SKU includes a -100 adjustment code, you can dial the 165mm nominal stroke back by up to 100mm, creating a highly flexible 65-165mm usable travel window for precise product changeovers.
This variant features a SUS420J2 stainless steel rod (code A) for superior corrosion resistance and ships with a magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and the approved mounting set includes 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 SAIJ80AX165-100S Is Used
Variable Product Changeover
Ideal for packaging lines that process different carton sizes, using the 65-165mm travel window to rapidly reconfigure the retract end position without changing hardware.
Machine Setup Tuning
Allows maintenance teams to fine-tune the exact end-of-stroke position during commissioning, absorbing mechanical tolerances directly via the rear stopper screw.
Sensor-Ready Actuation
The integrated magnet works seamlessly with DMSE solid-state sensors in automated assembly cells, providing reliable position feedback in dynamic environments.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX165-100S the Right Cylinder?
The wide 65-165mm adjustable window is ideal for machines running multiple product sizes, allowing operators to fine-tune the retract end position at commissioning without swapping cylinders or adding external stops. For fixed-travel applications without changeover needs, a standard SAI cylinder is more appropriate.
When specifying a replacement, ensure you match the 80mm bore, 165mm stroke, 100mm adjustment, PT tapered port threads, and the -S magnet. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true pneumatic locking, consider the SAIL or BSAI series. Since the stroke is under 300mm, side-load stress on the 25mm rod is manageable, but external guides remain recommended for heavy lateral loads.
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 SAIJ80AX165-100S FAQ
At 0.7MPa, the push force increases to 3518N.
The rear adjuster screw allows you to shorten the 165mm nominal stroke by up to 100mm, providing a usable travel range of 65-165mm. This stopper sets the end position but does not lock the load without continuous air pressure.
