About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX180-10S
The AirTAC SAIJ80X180-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 170-180 mm usable travel window, allowing you to dial back the 180 mm nominal stroke by up to 10 mm during commissioning without swapping out the unit.
This variant features a SUS304 stainless steel rod for corrosion resistance and includes a magnet for CMSE and DMSE sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and the PT tapered ports ensure tight pneumatic connections. The rear adjuster acts purely as a mechanical stop to fine-tune the retract end position and 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 SAIJ80BX180-10S Is Used
Machine Changeover
Dial in the 170-180 mm travel window during product size transitions without physically replacing the cylinder or adding external stopper blocks.
End-Position Tuning
Fine-tune the retract end-stop during initial commissioning to absorb mechanical tolerances and achieve exact positioning.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX180-10S the Right Cylinder?
Select this 80 mm bore cylinder when an application requires high force combined with precise end-position tuning at machine changeover. If your setup needs less force, stepping down to a 63 mm bore yields 1559N at 0.5 MPa; stepping up to a 100 mm bore provides 3927N at the same pressure. Because the 180 mm stroke is under the 300 mm threshold, side-load risks are moderate, but an external guide is still recommended for heavy lateral loads.
This adjustable model is chosen over a fixed SAI cylinder when you need a variable end-stop rather than a rigid travel length. Remember that the rear adjuster is a travel stop, not a locking mechanism. For true load-holding without continuous air pressure, consider an AirTAC SAIL or BSAI cylinder. This unit is dimensionally interchangeable with ISO 15552 cylinders, featuring a G3/8 port, PT thread, and a Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting interface.

- ✓ 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 SAIJ80BX180-10S FAQ
At 0.9 MPa, the push force increases to 4523N.
The rear adjuster screw lets you shorten the 180 mm nominal stroke by up to 10 mm, creating a 170-180 mm travel window. It acts as a mechanical stop and does not lock the load without live air pressure.
