About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX120-30
The AirTAC SAIJ160X120-30 is a double-acting ISO 15552 profile cylinder featuring a rear mechanical stroke adjuster. It provides a nominal 120 mm travel that can be fine-tuned backward by up to 30 mm, yielding a precise 90-120 mm usable window.
This unit specifies a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets. The rear stopper acts purely as a travel end-limit, meaning it will not hold a load without live air pressure.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 9425 N | 9425 N |
| 0.7 MPa | 13195 N | — |
| Max (@1.0 MPa) | 1922 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 SAIJ160 Adjustable Cylinder SAIJ160BX120-30 Is Used
Heavy Press Tuning
Dial in the exact 90-120 mm travel window during setup to accommodate varying material thicknesses in heavy pressing operations without adding external stops.
Product Changeover
Quickly adjust the retract end-position on packaging lines when switching between different product sizes, leveraging the 30 mm trim range for rapid format changes.
Corrosive Forming
Utilize the SUS304 stainless steel rod in humid or washdown metal-forming environments where carbon steel rods would degrade, ensuring reliable high-force output.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX120-30 the Right Cylinder?
The 30 mm adjustment range is ideal for dialing in exact end-stops during machine commissioning or product changeover without swapping hardware. Because the stroke is under 300 mm, the 40 mm rod and M36x2 thread handle standard side loads well, though external guides are always recommended for rigid payloads.
For direct ISO 15552 interchangeability, match the 160 mm bore, 120 mm stroke, PT port threads, and SUS304 rod material. If your application requires the cylinder to hold its position without continuous air pressure, this plain SAIJ is insufficient; consider an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder 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 SAIJ160 Adjustable Cylinder SAIJ160BX120-30 FAQ
It can reach up to 2050 kgf at its maximum 1.0 MPa pressure rating.
The rear adjuster screw mechanically limits the piston's retract travel. For this 120 mm nominal stroke cylinder, you can trim the effective travel back by up to 30 mm, creating a usable 90-120 mm window. It acts as a physical stop and does not lock the load without live air.
