About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX450-75S
The AirTAC SAIJ80X450-75-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. The extruded aluminum barrel includes sensor grooves on both sides for straightforward position detection.
This variant features a SUS420J2 stainless steel rod (code A) for improved corrosion resistance and ships with a magnet (-S) compatible with AirTAC CMSE reed and DMSE electronic sensors. The 25mm rod and M20x1.5 thread provide robust support, though the 450mm length means an external guide is recommended to manage side loads. It uses a G3/8 port and omits FB, CA, CB, and CR mounts, utilizing a focused set of Basic, FA, LB, TC, FTC, TCM1, and TCM2 hardware.

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 SAIJ80AX450-75S Is Used
Product Size Changeovers
Dial in the 375-450mm travel window during line format changes to accommodate different product lengths without physically swapping the actuator.
Adjustable Diverting
Fine-tune the retract end-stop on a sorting pusher to handle varying package depths on the fly, ensuring precise positioning at commissioning.
Machine Setup Calibration
Trim the 450mm stroke by up to 75mm to perfectly time a heavy press or clamping motion, avoiding the need to bolt on external mechanical stops.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX450-75S the Right Cylinder?
The adjustable stroke is ideal for product changeovers, allowing you to dial in the end position without swapping cylinders or adding external stops.
For ISO 15552 replacement matching, specify the 80mm bore, 450mm stroke, 75mm adjustment range, PT tapered port thread, and the -S magnet. Note that the rear adjuster acts as a travel stop, not a lock; it cannot hold a load without live air. For fail-safe load holding, consider an AirTAC SAIL or BSAI cylinder, or an external rod lock. Because the 450mm stroke exceeds 300mm, external guiding is necessary to prevent excessive side-loading on the rod.
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 SAIJ80AX450-75S FAQ
At 0.7MPa, the push force increases to 3518N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 450mm nominal stroke by up to 75mm, yielding a usable travel window of 375-450mm. It sets the end position but does not lock the load without continuous air pressure.
