About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX140-10
The AirTAC SAIJ80X140-10 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. This fine-tuning capability eliminates the need to swap cylinders or bolt on external stops when dialing in final end positions.
This bore size utilizes a G3/8 port and a robust 25mm piston rod with an M20x1.5 thread. Supplied here with a SUS304 stainless steel rod (code B) and PT tapered port threads, it handles demanding environments. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets.

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 SAIJ80BX140-10 Is Used
Product Size Changeovers
Quickly dial in the 130-140mm travel window during format changeovers on packaging lines, using the rear screw to set new end positions without changing hardware.
End-Position Tuning
Fine-tune the final retract position during machine commissioning to prevent mechanical crashes, relying on the 10mm adjustment range to perfect the stop.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX140-10 the Right Cylinder?
The adjustable rear stopper is ideal for product-size changeovers on a line, offering variable end-stops without replacing the entire actuator. Remember that the rear adjuster functions purely as a travel stop, not a lock; the cylinder cannot hold a load without live air. For load-holding requirements without continuous pressure, consider an AirTAC SAIL or BSAI cylinder.
To match this exact ISO 15552 interchangeable replacement, specify an 80mm bore, 140mm stroke, 10mm adjustment range, PT port threads, SUS304 stainless steel rod material, and no magnet. Since the nominal stroke is under 300mm, side-load stress on the 25mm rod is manageable without external guides, though standard alignment practices still apply.
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 SAIJ80BX140-10 FAQ
At 0.7 MPa, the push force increases to 3518N.
The rear adjuster acts as an external stopper that allows you to shorten the 140mm nominal stroke by up to 10mm, creating a 130-140mm usable travel window. It sets the end position but does not lock the load without live air pressure.
