About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX85-10S
The AirTAC SAIJ80X85-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering a robust 2513N push force at 0.5 MPa. By turning the external stopper screw, you can trim the effective travel within a precise 75-85mm window, perfect for dialing in end positions during commissioning without swapping hardware.
This variant features an SUS420J2 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE and DMSE sensors. It uses a PT G3/8 port and retains the standard extruded aluminum barrel, while offering a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX85-10S Is Used
Machine Changeover
Quickly dial in the 75-85mm retract position when switching product sizes on a packaging line, avoiding mechanical teardown.
End-Stop Tuning
Fine-tune the final resting position of a heavy press tool during commissioning to achieve exact dimensional accuracy.
Variable Diverter Stroke
Adjust the pusher stroke length on the fly to accommodate different package widths without adding external hard stops.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX85-10S the Right Cylinder?
Choose this 80mm bore when an application requires substantial thrust that a 50mm bore (982N push at 0.5 MPa) cannot provide, but without stepping up to a 100mm unit. The 10mm adjustment window is ideal for product-size changeovers on a line, letting you fine-tune the retract stop on the fly instead of installing fixed spacers.
For an exact ISO 15552 replacement, match the 80mm bore, 85mm stroke, PT G3/8 port, SUS420J2 rod, and -S magnet. Remember that the rear adjuster acts only as a travel stop, not a lock; if you need to hold a load without live air pressure, consider an AirTAC SAIL or BSAI cylinder.
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 SAIJ80AX85-10S FAQ
At 0.5 MPa operating pressure, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. At 0.7 MPa, the push force increases to 3518N.
The rear adjuster screw acts as a mechanical stop that trims the nominal 85mm stroke back by up to 10mm, creating a usable travel window of 75-85mm. It sets the end position but does not lock the load without live air.
