About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX240-10
The AirTAC SAIJ80X240-10 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 230-240mm usable travel window, letting you dial back the nominal 240mm stroke by up to 10mm during commissioning.
The extruded aluminum barrel features sensor grooves on both sides for mounting CMSE reed or DMSE electronic solid-state switches. This specific configuration uses a SUS304 stainless steel rod (code B) for superior corrosion resistance and ships with PT tapered port threads. The rear adjustment screw acts purely as a travel stop for end-position tuning and does not lock 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 SAIJ80BX240-10 Is Used
End-Stop Calibration
Dial in the exact 230-240mm travel window during machine setup to perfect positioning without swapping cylinders.
Product Changeover
Quickly adjust the retract stop by up to 10mm on packaging lines when handling slightly different product sizes.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX240-10 the Right Cylinder?
The 10mm adjustable window is ideal for applications requiring exact end-stop tuning without adding external shims. Because the stroke is 240mm, the 25mm rod and M20x1.5 thread provide excellent rigidity, though you should still use an external guide for heavy lateral loads.
This model serves as a direct ISO 15552 dimensionally interchangeable replacement. Match your exact bore, 240mm stroke, 10mm adjustment, PT port threads, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting interface. Note that the SAIJ mounting set omits FB, CA, CB, and CR brackets. For load-holding without live air pressure, consider the SAIL or BSAI series instead.
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 SAIJ80BX240-10 FAQ
At the maximum operating pressure of 1.0 MPa, it delivers a maximum push force of 513 kgf.
The rear adjuster screw lets you shorten the effective travel from the nominal 240mm down to 230mm. This stop fine-tunes the retract end position but does not hold the load without live air pressure.
