About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX140-10S
The AirTAC SAIJ80X140-10-S is a double-acting ISO 15552 profile cylinder with a rear-mounted stroke adjuster. It provides a 130-140 mm usable travel window, allowing you to dial back the 140 mm nominal stroke by up to 10 mm during commissioning.
This variant features an SUS420J2 stainless steel rod and a built-in magnet for position sensing with CMSE reed or DMSE electronic switches. The extruded aluminum barrel includes sensor grooves on both sides. The rear adjuster acts purely as a mechanical stop to fine-tune the retract end position without adding external stops, but it does not lock 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 SAIJ80AX140-10S Is Used
End-Position Tuning
Dial in the exact retract distance within the 130-140 mm window during machine commissioning to perfect product handling without physical spacers.
Product Changeover
Quickly adjust the stroke end-stop by up to 10 mm when switching between slightly different product sizes on the same production line.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX140-10S the Right Cylinder?
The 10 mm adjustment range is ideal for product changeover or fine-tuning machine setup without swapping cylinders. If you need less force, a 50 mm bore offers 982 N; if you need more, a 100 mm bore provides 3927 N.
For an exact ISO 15552 replacement match, ensure the 140 mm stroke, 10 mm adjustment, PT tapered port threads, and the -S magnet option are specified. The 25 mm rod and M20x1.5 thread provide robust resistance to side loads, though any stroke over 100 mm still requires an external guide to prevent rod binding. If your application requires true load-holding without live air, consider the SAIL or BSAI series instead of relying on the SAIJ adjuster.
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 SAIJ80AX140-10S FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 513 kgf.
The rear adjuster screw lets you shorten the effective travel from the 140 mm nominal stroke down to 130 mm. This mechanical stop fine-tunes the retract end position during setup but does not lock the load without continuous air pressure.
