About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX90-75
The AirTAC SAIJ80X90-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel. With a nominal 90 mm stroke and a 75 mm adjustment range, it provides a highly versatile 15-90 mm usable travel window for precise end-position tuning during commissioning.
This model is configured with an SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and uses PT tapered port threads. It features variable air cushions at both ends to manage kinetic energy. The rear adjuster acts purely as a mechanical stop to set the retract position and does not hold the load without live air pressure; for fail-safe load holding, consider the SAIL or BSAI series.

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 SAIJ80AX90-75 Is Used
Product Changeover
Dial in the exact end-stop for different product lengths on a single line without physically replacing the actuator.
Commissioning Tuning
Fine-tune the 15-90 mm travel window during machine setup to perfect positioning without adding external stops.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX90-75 the Right Cylinder?
The 75 mm adjustment range is exceptionally wide, allowing a single cylinder to cover varied product sizes on a changeover line. Because the nominal stroke is under 300 mm, side-load stress on the 25 mm rod is moderate, though external guides are always recommended for offset loads.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 90 mm stroke, PT G3/8 ports, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that FB, CA, CB, and CR mounts are omitted from this adjustable series. As no magnet is specified, this unit cannot host CMSE reed or DMSE electronic sensors without modification.
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 SAIJ80AX90-75 FAQ
A rear external screw acts as a mechanical stopper, allowing you to shorten the nominal 90 mm stroke by up to 75 mm. This creates a 15-90 mm adjustable travel window. The adjuster only sets the end position; it does not lock the load without live air pressure.
At 0.7 MPa, the push force increases to 3518 N.
