About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX120-20
The AirTAC SAIJ160X120-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end position during commissioning. With a nominal 120 mm stroke and a 20 mm adjustment range, it provides a usable travel window of 100-120 mm, letting you dial in the exact retract distance without adding external stops. It delivers a robust 10053 N pull force at 0.5 MPa, making it well-suited for heavy-duty positioning tasks.
This variant 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 for mounting position switches. The rear adjuster acts purely as a travel stop to set the end position; it does not lock or hold the load without continuous air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

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 SAIJ160BX120-20 Is Used
Product Changeovers
Quickly adapt to varying package sizes on a packaging line by dialing the rear adjuster to shift the retract end-stop within the 100-120 mm window.
Heavy-Duty Clamping
Provides immense clamping force for holding large metal castings in place during machining, using the fine-tuned stroke to prevent over-travel.
Commissioning Calibration
Perfect for new machine setups where the exact final position is unknown, allowing operators to trim the stroke by up to 20 mm without installing external mechanical stops.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX120-20 the Right Cylinder?
Choose this 160 mm bore cylinder when your application requires high force, offering 10053 N of pull force at 0.5 MPa. If your setup needs less force, stepping down to a 125 mm bore yields 5734 N of pull force at the same pressure. The adjustable stroke is ideal for machine changeovers where product sizes vary, allowing you to reposition the end-stop quickly rather than swapping out a fixed-stroke SAI cylinder.
Because this model has a 120 mm stroke, it falls below the 300 mm threshold, so side-loading risks are minimal, though an external guide is still recommended for heavy off-center loads. This SKU is dimensionally interchangeable per ISO 15552 and includes a PT port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting options, and no magnet sensor (-S).
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 SAIJ160BX120-20 FAQ
It can deliver up to 2050 kgf at its maximum 1.0 MPa pressure rating.
The rear adjuster allows you to shorten the nominal 120 mm stroke by up to 20 mm, creating a usable travel window between 100 and 120 mm. It acts as a mechanical stop to set the retract position and does not function as a load lock.
