About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX120-40
The AirTAC SAIJ160X120-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits on-the-fly end-position tuning. With a nominal 120 mm stroke and a 40 mm adjustment range, it provides an effective usable travel window of 80 to 120 mm.
This SKU features 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 unit reaches speeds of 30-500 mm/s. The rear adjuster acts purely as a travel stop for deceleration and does not lock the 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 SAIJ160BX120-40 Is Used
Heavy Press Tuning
Dial in the exact 80-120 mm travel end-stop during setup to prevent over-travel when pressing heavy plates.
Product Changeover
Quickly adjust the retract position for different product sizes on a conveyor line without changing the cylinder.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX120-40 the Right Cylinder?
The 40 mm adjustment range is ideal for fine-tuning the retract end during machine commissioning or product changeover without swapping the cylinder or adding external stops. For load-holding without continuous air pressure, this cylinder is insufficient as the adjuster is only a stop; consider an AirTAC SAIL or BSAI series instead. When ordering a replacement, match the 160 mm bore, 120 mm nominal stroke, 40 mm adjuster, PT G3/4 port, and the SUS304 (B) rod option. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ160BX120-40 FAQ
At the maximum 1.0 MPa, the push force reaches 18095 N.
The rear adjuster screw lets you shorten the nominal 120 mm stroke by up to 40 mm, giving an effective travel window of 80 to 120 mm. It acts as a mechanical stop for end-position tuning and does not function as a lock.
