About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX230-30
The AirTAC SAIJ80X230-30 is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. The built-in adjuster allows you to trim the effective travel back by up to 30 mm, providing a usable stroke window of 200-230 mm for precise end-position tuning without adding external stops.
This variant features an SUS420J2 stainless steel piston rod (code A) for enhanced corrosion resistance. It uses PT tapered port threads (G3/8) and operates at speeds between 30-800 mm/s. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE reed or DMSE electronic switches if a magnet is added later.

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 SAIJ80AX230-30 Is Used
Product Changeover
Dial in the 200-230 mm travel window during line format changes to accommodate different package sizes without physically replacing the actuator.
End-Position Tuning
Fine-tune the retract end-stop during commissioning to perfect tooling alignment, absorbing mechanical tolerances directly at the rear adjuster.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX230-30 the Right Cylinder?
The adjustable 200-230 mm travel window is ideal for machine setups requiring variable end-stops or product-size changeovers, saving the cost of swapping a fixed-stroke SAI cylinder. Remember that the rear adjuster is a travel stop, not a lock; the SAIJ cannot hold a load without live air. For dead-load holding, select an external rod lock or a BSAI clamp-lock cylinder.
To match this ISO 15552 dimensionally interchangeable profile cylinder, confirm the 80 mm bore, 230 mm nominal stroke, 30 mm adjustment range, G3/8 PT ports, and mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that FB, CA, CB, and CR mounts are omitted from the SAIJ series.
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 SAIJ80AX230-30 FAQ
At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster acts as a mechanical stop that lets you shorten the 230 mm nominal stroke by up to 30 mm, creating a 200-230 mm usable travel window. It sets the retract end-position but does not lock the load without continuous air pressure.
