About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX180-10S
The AirTAC SAIJ80X180-10-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 180 mm stroke that can be fine-tuned down by up to 10 mm, giving you a precise 170-180 mm usable travel window during commissioning.
This variant features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and includes a built-in magnet (-S) for position detection. You can mount CMSE reed or DMSE electronic solid-state switches directly into the sensor grooves machined on both sides of the extruded aluminum barrel. The rear stopper sets the end position, but remember it acts purely as a travel stop, not a load lock.

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 SAIJ80AX180-10S Is Used
Precision End-Stop Tuning
Dial in the exact 170-180 mm travel distance during machine commissioning to perfect part seating without swapping hardware.
Product Changeover
Quickly adjust the rear stopper by up to 10 mm to accommodate slightly different product sizes on the same line.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX180-10S the Right Cylinder?
The 10 mm adjustment range is ideal for dialing in exact end-of-stroke positions during machine setup or product changeovers, avoiding the need to bolt on external stops. If your application requires holding the load without live air pressure, this cylinder will not suffice; you should look at the SAIL or BSAI locking variants instead.
For this 180 mm stroke, the 25 mm rod diameter and M20x1.5 rod thread provide robust resistance to moderate side loads, though any long unsupported travel still requires an external guide. This configuration uses PT tapered ports and supports the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). It is dimensionally interchangeable per ISO 15552.
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 SAIJ80AX180-10S FAQ
At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster screw allows you to shorten the 180 mm nominal stroke by up to 10 mm, creating a 170-180 mm usable travel window. This mechanism acts as a travel stop and does not lock the load without live air pressure.
