About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX175-20
The AirTAC SAIJ80X175-20 is a double-acting, double-rod ISO 15552 profile cylinder engineered with a rear stroke adjuster. By turning the rear screw, you can trim the effective travel back by up to 20mm, creating a precise 155-175mm usable stroke window during commissioning without swapping out the unit.
This bore size utilizes a G3/8 port and dual-side variable air cushions to manage kinetic energy at the travel ends. The rod is constructed from SUS420J2 stainless steel for enhanced corrosion resistance, and the extruded aluminum barrel includes sensor grooves on both sides. Note that the rear adjuster acts strictly as a travel stop and does not lock the load without live air pressure.

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 SAIJ80AX175-20 Is Used
Product Changeovers
Quickly dial in the 155-175mm stroke window during packaging line format changes to accommodate different carton sizes without changing hardware.
End-Stop Calibration
Fine-tune the exact retraction point during machine commissioning to prevent mechanical interference, using the rear adjuster instead of external shims.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX175-20 the Right Cylinder?
The adjustable stroke is ideal for machine setups requiring variable end-stops or product changeovers, allowing you to fine-tune the 155-175mm travel window on the fly instead of installing fixed-stroke SAI cylinders. For true load-holding without continuous air pressure, integrate an external pilot-operated check valve or select a SAIL lock variant.
To match this ISO 15552 interchangeable cylinder exactly, specify the 80mm bore, 175mm nominal stroke, 20mm adjustment range, PT tapered port threads, and standard mounting options (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the 175mm stroke is relatively short for this bore, side-load stress is minimal, but external guides are still recommended if the load is heavy or offset.
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 SAIJ80AX175-20 FAQ
At 0.7 MPa, the push force increases to 3518N.
The rear adjuster screw allows you to shorten the 175mm nominal stroke by up to 20mm, providing an effective travel window of 155-175mm. This stopper sets the end position but does not hold the load without live air pressure.
