About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX190-20
The AirTAC SAIJ80X190-20 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 190 mm stroke that can be fine-tuned down by up to 20 mm, creating a precise 170-190 mm usable travel window during commissioning.
This variant features a SUS420J2 stainless steel rod for improved corrosion resistance and utilizes PT tapered port threads with a G3/8 connection. The rear adjuster acts purely as a mechanical stop to set the end position, meaning it does not hold the load without live air pressure. For load-holding requirements, an external rod lock or SAIL cylinder is required.

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 SAIJ80AX190-20 Is Used
Product Changeover
Dial in the 170-190 mm travel window on the fly to accommodate different package sizes on a packaging line without changing hardware.
End-Stop Calibration
Use the rear adjuster to precisely set the retract position during machine setup, ensuring perfect alignment for high-precision pressing tasks.
Variable End Positioning
Ideal for automated assembly stations where the final end-stop needs slight mechanical trimming to perfect the tooling clearance.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX190-20 the Right Cylinder?
The 20 mm adjustment range is ideal for applications needing exact end-position tuning at commissioning or frequent product-size changeovers, avoiding the need to bolt on external stops. Because the 190 mm stroke is under 300 mm, side-load stress is moderate, but external guiding remains recommended for heavy off-center loads.
To match this exact configuration for an ISO 15552 replacement, specify: 80 mm bore, 190 mm stroke, 20 mm adjustment, G3/8 PT ports, SUS420J2 rod material, and no magnet. It supports the standard SAIJ mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets.
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 SAIJ80AX190-20 FAQ
At 0.7 MPa, the push force increases to 3518 N.
The rear mechanical stopper allows you to shorten the effective stroke by up to 20 mm, providing a usable travel window of 170 to 190 mm. It functions as an end-stop, not a lock, so live air pressure is still required to hold the load.
