About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX180-10
It features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads with a G3/8 connection. By turning the rear screw, you achieve a usable travel window of 170-180mm, allowing precise end-position tuning without swapping the cylinder.
This adjustable stopper fine-tunes the retract position during commissioning or product changeovers, eliminating the need for external stops. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE or DMSE switches if a magnet is added later. It supports a mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.

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 SAIJ80BX180-10 Is Used
End-Stop Tuning
Dial in the exact 170-180mm retract position during machine commissioning to perfect product placement without machining external spacers.
Product Changeover
Quickly adjust the stroke by up to 10mm on a packaging line when switching to a slightly different package size, minimizing downtime.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX180-10 the Right Cylinder?
The 10mm adjustment window is ideal for dialing in exact end-stops during machine setup. When specifying a replacement, match the 80mm bore, 180mm stroke, PT port thread, and the chosen mounting style. Note that this SKU does not include a magnet; adding an -S variant is required for electronic or reed sensor feedback.
Because the 180mm stroke is relatively short, side-load stress is minimal, though the 25mm rod diameter handles standard loads well. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for pilot-operated locking, consider the SAIL or BSAI series.
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 SAIJ80BX180-10 FAQ
At 0.7 MPa, the push force increases to 3518N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 180mm nominal stroke by up to 10mm, creating a 170-180mm travel window. It only sets the end position and does not lock the load without continuous air pressure.
