About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX90-75S
The AirTAC SAIJ80X90-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window from 15 to 90 mm without adding external stops. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting.
This variant is equipped with a SUS420J2 stainless steel rod (code A) for superior corrosion resistance and includes a built-in magnet (-S) that operates seamlessly with CMSE reed and DMSE electronic solid-state sensors. The rear adjustment screw acts purely as a mechanical stop to set the end position and does not hold 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 SAIJ80AX90-75S Is Used
Product Changeover
Rapidly dial in the stroke from 90mm down to 15mm when switching machinery to handle a different product size, eliminating the need to physically swap cylinders.
End-Stop Calibration
Precisely set the retract end-position during machine commissioning to prevent mechanical crashes, using the rear screw rather than relying on fixed stops.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX90-75S the Right Cylinder?
The SAIJ80X90-75-S is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). It features PT tapered port threads (G3/8) and a 25mm rod with an M20x1.5 thread. For load-holding without live air pressure, consider the SAIL or BSAI series, as the adjuster here is strictly a travel stop.
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 SAIJ80AX90-75S FAQ
The rear adjuster screw acts as a mechanical stop that trims the effective stroke. For this model, you can reduce the nominal 90mm stroke by up to 75mm, providing a usable travel window of 15 to 90mm. It only sets the end position and does not lock the load without air pressure.
At 0.9 MPa, the push force increases to 4523N.
