About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX180-40
The AirTAC SAIJ80X180-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 180 mm travel that can be fine-tuned down by up to 40 mm, yielding a precise 140-180 mm usable window.
This unit utilizes a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads with a G3/8 connection. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE or DMSE switches if a magnet is added later. The rear stopper sets the travel limit but does not lock the load without continuous 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.

Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX180-40 the Right Cylinder?
If your setup requires less force, stepping down to a 63 mm bore yields 1559 N; if more power is needed, a 100 mm bore provides 3927 N. Because the stroke is 180 mm, side-load risks are moderate, but always ensure external guides support the load to prevent binding.
To match this ISO 15552 interchangeable cylinder, confirm the 80 mm bore, 180 mm nominal stroke, 40 mm adjustment range, PT G3/8 port, and SUS304 rod material. The available mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2. For applications requiring the load to be held mechanically without air pressure, select a SAIL or BSAI cylinder instead, as the SAIJ adjuster acts only as a travel stop.
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 SAIJ80BX180-40 FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 513 kgf.
The rear adjuster acts as a mechanical stop, allowing you to shorten the effective travel from the 180 mm nominal stroke down to 140 mm. It decelerates the piston but does not lock the load without live air pressure.
