About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX325-10S
The AirTAC SAIJ80X325-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 315 to 325 mm.
This adjustable-stroke model allows you to fine-tune the retract end position directly at commissioning without swapping the cylinder or adding external stops. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches.

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 SAIJ80BX325-10S Is Used
Precision Machine Setup
Dial in the exact 315-325 mm retract position during commissioning to perfect part seating without reprogramming fixed stops.
Product Changeover
Quickly adjust the end-of-stroke position by up to 10 mm on packaging lines when switching to slightly different product sizes.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX325-10S the Right Cylinder?
Choose this 80 mm bore when an application requires higher thrust than a 63 mm cylinder (1559 N at 0.5 MPa) but less than a 100 mm bore (3927 N). The 10 mm adjustment window is ideal for precision machine setup and product changeovers, letting you dial in the exact end-stop mechanically rather than reprogramming fixed SAI cylinder limits. Because the stroke is 325 mm, an external guide is recommended to prevent excessive side loading on the rod.
For an exact ISO 15552 replacement, match the 80 mm bore, 325 mm stroke, PT tapered port thread, and -S magnet option. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for fail-safe 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 SAIJ80BX325-10S FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective travel from the nominal 325 mm down to 315 mm. This creates a 315-325 mm usable window for fine-tuning the end position without altering the cylinder mount.
