About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX225-75
The AirTAC SAIJ80X225-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 75 mm. This creates a highly versatile 150-225 mm usable window, letting you dial in the exact retract end-position during commissioning without swapping hardware.
This SKU is configured with a SUS304 stainless steel rod (code B) for superior corrosion resistance and features PT tapered port threads (G3/8). The extruded aluminum barrel includes sensor grooves on both sides, allowing you to add CMSE or DMSE switches later if position feedback becomes necessary.

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 SAIJ80BX225-75 Is Used
Variable End-Stop Tuning
Ideal for machines requiring frequent reconfiguration of the retract distance, using the 75 mm adjustment window to adapt stroke limits without replacing the cylinder.
Product Changeover
Enables rapid format adjustments on packaging lines, allowing operators to dial in the 150-225 mm travel window to accommodate different carton sizes on the fly.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX225-75 the Right Cylinder?
The generous 75 mm adjustment range is ideal for product-size changeovers on a packaging line, allowing operators to set new retract stops quickly instead of installing a fixed-stroke SAI cylinder or fabricating external mechanical stops.
Because the nominal stroke is 225 mm, the 25 mm rod and M20x1.5 rod thread provide excellent structural rigidity, though any long, unsupported load still requires an external guide to prevent side-loading damage. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true pneumatic locking without pressure, consider an AirTAC SAIL or BSAI cylinder. This model is dimensionally interchangeable per ISO 15552 and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
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 SAIJ80BX225-75 FAQ
If you increase the pressure to 0.7 MPa, the push force rises to 3518 N.
The rear adjuster screw acts as a mechanical stop that shortens the 225 mm nominal stroke by up to 75 mm, giving a usable travel window of 150 to 225 mm. It only sets the end position and does not lock the load without continuous air pressure.
