About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX225-20S
The AirTAC SAIJ80X225-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a usable travel window of 205 to 225 mm.
This adjustable-stroke model allows you to fine-tune the retract end position during commissioning without swapping hardware or adding external stops. It retains the standard ISO 15552 mounting interface but uses a reduced bracket set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR options.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
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 SAIJ80BX225-20S Is Used
Product Changeover
Dial in the 205-225 mm travel window during line format changes to accommodate different package depths without replacing the cylinder.
End-Stop Tuning
Fine-tune the retract position at commissioning to achieve precise mechanical alignment, avoiding the need to add external shims or stops.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX225-20S the Right Cylinder?
The 20 mm adjustment window is ideal for product changeovers, letting you dial in the exact end-stop mechanically. Because the stroke is 225 mm, ensure external guiding is used to handle side loads on the 25 mm rod.
For a direct ISO 15552 replacement, match the 80 mm bore, 225 mm stroke, 20 mm adjust code, PT tapered port threads, and the -S magnet option. Note that the rear adjuster functions strictly as a travel stop and does not hold the load without live air; for true load-holding, 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 SAIJ80BX225-20S FAQ
The rear adjuster acts as a mechanical stop that allows you to shorten the effective stroke by up to 20 mm, creating a usable travel window of 205 to 225 mm. It functions as a travel stop and does not lock the load without continuous air pressure.
