About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX180-30
The AirTAC SAIJ80X180-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 150 to 180 mm, letting you dial back the nominal 180 mm stroke by up to 30 mm during commissioning.
This specific SKU is configured with an SUS420J2 stainless steel rod (option A) for improved corrosion resistance compared to standard carbon steel. The cylinder uses PT tapered port threads (G3/8) and operates without a magnet. The extruded aluminum barrel incorporates sensor grooves on both sides, allowing for direct mounting of position switches if retrofitted 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 SAIJ80AX180-30 Is Used
End-Position Tuning
Fine-tune the retraction point within the 150-180 mm window during machine commissioning without adding external physical stops.
Product Changeover
Quickly adjust the stroke length on automated lines handling varying product sizes by dialing the rear screw up to 30 mm.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX180-30 the Right Cylinder?
The adjustable stroke is ideal for machine setups requiring variable end-stops or product changeovers, preventing the need to swap out a fixed-stroke SAI cylinder. To match an ISO 15552 replacement, verify the 80 mm bore, 180 mm stroke, 30 mm adjustment range, PT G3/8 port, and basic mounting interface.
Because the 180 mm stroke is under the 300 mm threshold, side-load risks are moderate, but the 25 mm rod diameter and M20x1.5 rod thread handle lateral stress well. Remember that the rear adjuster acts only as a travel stop; it does not hold the load without live air pressure. For dead-end load holding, consider an external pilot-operated check valve or the SAIL lock 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 SAIJ80AX180-30 FAQ
The rear adjuster screw lets you shorten the effective travel from 180 mm down to 150 mm. It acts as a mechanical stop to set the retract end-position precisely, but it is not a lock and requires live air to hold the load.
At 0.7 MPa, the push force increases to 3518 N.
