About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX195-50
The AirTAC SAIJ80X195-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the nominal 195 mm travel back by up to 50 mm. This creates a highly flexible 145 to 195 mm usable stroke window, enabling precise end-position tuning at commissioning without swapping out the barrel or adding external stops.
This specific SKU is configured with an SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and utilizes PT tapered port threads with a G3/8 connection. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of equipment. The rear adjuster acts purely as a mechanical stop to set the retract position, meaning it will not hold the load dynamically 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 SAIJ80AX195-50 Is Used
End-Stop Calibration
Dial in the exact retract distance within the 145 to 195 mm window during machine commissioning to perfect product positioning without external stopper blocks.
Product Size Changeover
Quickly adapt a packaging line to varying package lengths by adjusting the rear stopper screw rather than replacing the entire actuator.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX195-50 the Right Cylinder?
The 25 mm rod diameter and M20x1.5 rod thread provide excellent rigidity and side-load capacity. For applications requiring true load-holding without continuous air pressure, this cylinder is not a lock; consider the SAIL (air-released lock) or BSAI (clamp-lock) series instead. When matching this ISO 15552 interchangeable cylinder for a retrofit, verify the 195 mm stroke, 50 mm adjuster, G3/8 PT ports, and the correct SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
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 SAIJ80AX195-50 FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 50 mm from the 195 mm nominal length. This provides a usable travel window of 145 to 195 mm, letting you fine-tune the end position without replacing the cylinder.
At the maximum 1.0 MPa pressure, it can deliver up to 513 kgf.
