About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX230-100
The AirTAC SAIJ80X230-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 2513N of push force at 0.5 MPa. Its defining feature is a 100mm adjustment range that creates a usable travel window between 130mm and 230mm. This allows precise end-position tuning at commissioning without swapping the cylinder or adding external stops.
Built with an SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance, this model uses PT tapered ports and operates at speeds of 30-800mm/s. The extruded aluminum barrel features sensor grooves on both sides, ready for CMSE or DMSE switches if a magnet is added later. The rear adjuster acts purely as a travel stop and does not hold the load without live air.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX230-100 Is Used
Product Changeovers
Dial in the 130-230mm travel window during format size changes on packaging lines without swapping hardware.
End-Position Tuning
Fine-tune the retract stroke during machine commissioning to perfect seating forces against the workpiece.
Variable End Stops
Provide flexible physical stops for assembly stations handling multiple part lengths on a single fixture.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX230-100 the Right Cylinder?
Select this 80mm bore when an application requires substantial force, stepping up from a 63mm cylinder that provides 1559N push at 0.5 MPa. The 100mm adjustment window is ideal for product-size changeovers on a line, allowing the retract end to be dialed back significantly without mechanical modifications. For load-holding without live pressure, an external rod lock or pilot-operated check valve is required, as the adjuster is a stop, not a lock.
As a dimensionally interchangeable ISO 15552 cylinder, replacement matching requires an 80mm bore, 230mm stroke, 100mm adjustment, PT ports, and the correct mounting set. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, explicitly omitting FB, CA, CB, and CR options. Because the 230mm stroke is moderately long, ensure external guidance is used to handle side loads and protect the M20x1.5 rod thread.
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 SAIJ80AX230-100 FAQ
At 0.5 MPa, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. If higher pressure is available, it can deliver up to 3518N push at 0.7 MPa.
The rear adjuster screw lets you shorten the effective stroke by up to 100mm, creating a usable travel window of 130mm to 230mm. It acts as a mechanical stop to set the end position and does not lock the load without live air.
