About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX225-50
The AirTAC SAIJ80X225-50 is a double-acting ISO 15552 profile cylinder with a rear-mounted stroke adjuster. It provides a 175-225 mm usable travel window, allowing you to dial back the 225 mm nominal stroke by up to 50 mm during commissioning. It delivers 2513 N of pull force at 0.5 MPa and reaches a maximum of 513 kgf at 1.0 MPa.
This model features a SUS304 stainless steel rod for corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. The rear adjuster acts purely as a mechanical stop to fine-tune the end position, meaning it does not hold 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 SAIJ80BX225-50 Is Used
Product Changeover
Dial in the 175-225 mm travel window during format size changes on a packaging line without replacing the cylinder.
End-Stop Tuning
Fine-tune the retract end-position at machine commissioning to avoid bolting on external mechanical stops.
Variable Positioning
Set precise retract distances for multi-stage pressing or clamping operations directly via the rear adjuster.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX225-50 the Right Cylinder?
Choose this 80 mm bore when a 63 mm bore (1402 N pull at 0.5 MPa) is too weak but a 100 mm bore is excessively large. The 50 mm adjustment range is ideal for product changeovers on a line, letting you set variable end stops without swapping the cylinder or adding external stopper blocks. For load-holding without continuous air pressure, this cylinder is insufficient; consider the SAIL or BSAI series instead.
Because the stroke is 225 mm, the M20x1.5 rod should be guided externally to prevent side-load damage. It is dimensionally interchangeable per ISO 15552 and uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ80BX225-50 FAQ
The rear adjuster is a mechanical stop that lets you shorten the 225 mm nominal stroke by up to 50 mm, creating a 175-225 mm usable travel window. It only sets the end position and does not lock or hold the load without live air pressure.
At the maximum operating pressure of 1.0 MPa, it delivers a maximum thrust of 513 kgf.
