About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX180-75S
The AirTAC SAIJ80X180-75-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. The built-in rear stopper provides a usable travel window of 105 to 180mm, allowing you to dial back the nominal stroke by up to 75mm during commissioning without swapping the cylinder.
This configuration includes an SUS420J2 stainless steel rod (material code A) for improved corrosion resistance and a magnet (-S) for position sensing. It uses PT tapered ports and supports AirTAC CMSE reed and DMSE electronic sensors mounted in the dual-side extruded barrel grooves. The generous 75mm adjustment range makes it highly effective for machines that frequently process varying product sizes.

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 SAIJ80AX180-75S Is Used
Product Changeovers
Dial in the 105 to 180mm stroke window on the fly to accommodate different package sizes on a packaging line without changing out the actuator.
Machine Setup
Fine-tune the retract end-position during initial commissioning, using the rear screw to set precise stopping points without machining external hard stops.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX180-75S the Right Cylinder?
Choose this adjustable-stroke SAIJ model over a fixed-stroke SAI when you need a 105 to 180mm travel window to accommodate product changeovers without adding external stops. To match this cylinder for an ISO 15552 replacement, specify the 80mm bore, 180mm stroke, 75mm adjustment, PT port thread, and the -S magnet. Note that the rear adjuster is a travel stop, not a lock; for load-holding 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 SAIJ80AX180-75S FAQ
The rear adjuster acts as an external stop that shortens the effective travel. For this model, you can trim the 180mm nominal stroke back by up to 75mm, creating a usable travel window of 105 to 180mm. The adjuster sets the end position but does not lock the load without live air.
It operates at a speed of 30-800 mm/s and features adjustable air cushions at both ends to decelerate the load smoothly.
