About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX120-40S
The AirTAC SAIJ160X120-40-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that allows you to fine-tune the end position. With a 120 mm nominal stroke and a 40 mm adjustment range, it provides a usable travel window of 80-120 mm, letting you dial in the exact retract distance without swapping out the cylinder or adding external stops. It delivers robust thrust, pushing 14074 N at 0.7 MPa and pulling 9425 N at 0.5 MPa.
This specific configuration includes a SUS304 stainless steel rod (code B) for superior corrosion resistance and features a built-in magnet (-S) for use with AirTAC CMSE reed and DMSE solid-state sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and the cylinder supports PT tapered port threading (G3/4) for secure pneumatic connections.

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 SAIJ160BX120-40S Is Used
Machine Setup Tuning
Dial in the exact 80-120 mm travel window during initial commissioning to perfectly align heavy stamping or press components without machining custom spacers.
Product Line Changeover
Quickly adjust the retract end-stop by up to 40 mm when switching between product sizes on a high-force assembly line, minimizing downtime.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX120-40S the Right Cylinder?
Choose this 160 mm bore cylinder when your application requires high force combined with precise end-position tuning at commissioning or during product changeover. Because the stroke is 120 mm, you do not need an external guide for side-load support, though the robust 40 mm rod and M36x2 thread naturally handle significant mechanical stress.
The rear adjuster acts strictly as a travel stop to set deceleration and end limits; it is not a locking mechanism. The SAIJ cannot hold a load without live air pressure, so for fail-safe load holding, consider the AirTAC SAIL or BSAI series instead. When matching ISO 15552 interchangeable replacements, ensure the target unit matches the 160 mm bore, 120 mm stroke, 40 mm adjustment, PT G3/4 port, and -S magnet specifications.
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 SAIJ160BX120-40S FAQ
The rear adjuster screw allows you to shorten the effective travel from the 120 mm nominal stroke down to a minimum of 80 mm. This creates an 80-120 mm adjustable window for fine-tuning the retract end position at commissioning without external stops.
