About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX280-10S
The AirTAC SAIJ80X280-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 270 to 280 mm. Delivering 2513 N of push force at 0.5 MPa, it handles robust actuation while allowing precise end-position tuning during commissioning without swapping out the cylinder. The extruded aluminum barrel features sensor grooves on both sides.
This variant includes a magnet (-S) for position detection and uses a SUS420J2 stainless steel rod (code A) for improved corrosion resistance. It is fitted with PT tapered ports and supports variable air cushions at both ends. The rear adjuster acts purely as a travel stop for deceleration, not a lock, so load holding requires live air or an external locking device.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX280-10S Is Used
Machine Changeover
Dial in the 270-280 mm travel window during product size changes to perfectly position stops without adding external shims.
Material Handling
Provides 2513 N of push force at 0.5 MPa to divert or lift heavier pallets on a packaging line.
End-Stop Calibration
Fine-tune the final retract position during commissioning to perfect pressing or clamping depth.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX280-10S the Right Cylinder?
Choose this 80 mm bore when an application requires higher thrust than the 50 mm class (982 N push at 0.5 MPa) but does not need the full output of a 100 mm cylinder (3927 N). The 10 mm adjustable stroke is ideal for fine-tuning the end stop during machine setup or product changeovers, offering more flexibility than a fixed-stroke SAI cylinder. For a true ISO 15552 replacement, match the 80 mm bore, 280 mm stroke, PT ports, and the -S magnet.
Because the 280 mm stroke is substantial, ensure external guiding is used to prevent excessive side-loading on the SUS420J2 rod. If the machine design requires the load to be held mechanically without continuous air pressure, integrate an external rod lock or select a related SAIL pneumatic lock cylinder instead of relying on the rear stopper. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ80AX280-10S FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster screw allows you to shorten the effective stroke by up to 10 mm, creating a 270-280 mm travel window. It functions as a mechanical stop to fine-tune the end position and does not lock the load without live air pressure.
