About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX155-30
The AirTAC SAIJ80X155-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 155 mm travel by up to 30 mm. This creates a usable 125-155 mm end-position window for fine-tuning during commissioning without adding external stops.
This SKU features a SUS420J2 stainless steel rod (option A) for improved corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic switches. The rear adjuster acts purely as a travel stop to set the retract 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 SAIJ80AX155-30 Is Used
Machine Changeover
Dial in the exact 125-155 mm retract position during product size changeovers without swapping the cylinder or adding external stopper blocks.
End-Position Tuning
Fine-tune the retract end-stop during commissioning to compensate for mechanical tolerance stack-up in your tooling.
Variable End Stops
Set precise retraction limits for automated clamping or pressing tasks where the nominal 155 mm stroke needs a 30 mm trim.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX155-30 the Right Cylinder?
The adjustable stroke is ideal for product changeovers on a line where exact retract positions vary slightly, unlike a fixed-stroke SAI cylinder. Because this is a double-acting cylinder, the rear adjuster only sets the travel end and is not a lock. For load-holding without live pressure, consider the SAIL or BSAI series. This model uses a PT port, PT/G thread interface, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR mounts.
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 SAIJ80AX155-30 FAQ
At 0.9 MPa, the push force increases to 4523 N.
The rear adjuster screw lets you shorten the 155 mm nominal stroke by up to 30 mm, providing a usable travel window of 125-155 mm. It acts as a mechanical stop and does not lock the load without air pressure.
