About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX325-10
The AirTAC SAIJ80X325-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling you to dial back the 325mm nominal travel to anywhere within a 315-325mm usable window. The barrel features sensor grooves on both sides for flexible switch placement.
This specific SKU features a SUS304 stainless steel piston rod for superior corrosion resistance and is fitted with PT tapered air ports. The rear adjustment mechanism acts purely as a travel stop to fine-tune the end position during commissioning; it does not lock or hold the load without live air pressure. For position-holding requirements, consider the SAIL or BSAI series instead.

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 SAIJ80BX325-10 Is Used
Machine Changeover
Dial in the exact end-stop position within the 315-325mm window during product size changes without physically swapping the cylinder.
Assembly Calibration
Fine-tune the 2513N clamping travel at commissioning to ensure precise, repeatable positioning of large components.
Variable End Stops
Adjust the retract position by up to 10mm to accommodate material thickness variations on automated production lines.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX325-10 the Right Cylinder?
If your process demands less force, stepping down to a 63mm bore yields 1559N; stepping up to a 100mm bore provides 3927N. The adjustable stroke is ideal for machine setup and product changeover, allowing you to trim up to 10mm of travel rather than swapping a fixed-stroke SAI cylinder.
Because the 325mm stroke is relatively long, the 25mm rod diameter should be supported by an external guide to prevent excessive side-loading and premature seal wear. This model uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. It is dimensionally interchangeable per ISO 15552 and uses PT ports without a magnet.
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 SAIJ80BX325-10 FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 513 kgf.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective travel from the nominal 325mm down to a minimum of 315mm. This creates a 315-325mm adjustable window for fine-tuning end positions at commissioning without replacing the cylinder.
