About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX75-75S
The AirTAC SAIJ80X75-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end position without adding external stops. With a nominal 75 mm stroke and a 75 mm adjustment range, it provides a highly flexible 0-75 mm usable travel window for precise product changeovers.
This variant includes a SUS420J2 stainless steel rod (code A) for improved corrosion resistance and features a built-in magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel retains standard ISO 15552 mounting dimensions, while the PT tapered port threads ensure a tight pneumatic seal.

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 SAIJ80AX75-75S Is Used
Variable End-Stop Tuning
Dial in the exact retraction point between 0 and 75 mm during machine commissioning to accommodate multiple product sizes on a single line.
Product Changeover
Quickly adjust the stroke window on packaging conveyors without physically swapping out the entire cylinder or adding bulky external mechanical stops.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX75-75S the Right Cylinder?
The rear adjuster on this SAIJ model acts purely as a travel stop for deceleration and positioning, not a lock. To hold a load securely without live air pressure, consider the SAIL or BSAI series instead. For exact ISO 15552 replacement matching, verify the 75 mm stroke, 75 mm adjustment, G3/8 port, PT threads, SUS420J2 rod, and the -S magnet requirement.
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 SAIJ80AX75-75S FAQ
The rear adjusting screw acts as a mechanical stopper, allowing you to trim the effective travel anywhere within a 0-75 mm window from the nominal 75 mm stroke. It sets the end position but does not lock the load without live air pressure.
At the maximum 1.0 MPa pressure, the push force reaches 513 kgf.
