About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX120-100S
Featuring a 160mm bore and a 120mm nominal stroke, the integrated stopper screw provides a 100mm adjustment range, yielding a highly flexible 20-120mm usable travel window for precise end-position tuning.
This unit includes a SUS304 stainless steel rod (option B) for superior corrosion resistance and carries the -S magnet option for seamless integration with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and the rear adjuster functions strictly as a travel stop to decelerate the load, not as a lock to hold it without live air.

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 SAIJ160BX120-100S Is Used
Variable End-Position Tuning
Dial in the exact retract distance from 20 to 120mm during machine commissioning to perfectly seat heavy components without adding external mechanical stops.
Corrosive Environment Actuation
Leverage the SUS304 stainless steel rod for high-thrust pressing or clamping tasks in washdown or chemically exposed environments while tracking position with DMSE sensors.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX120-100S the Right Cylinder?
If you need less force, stepping down to a 125mm bore yields 6136N; stepping up to a 200mm bore provides 15708N. To replace an ISO 15552 cylinder, match the 160mm bore, 120mm nominal stroke, 100mm adjustment, PT tapered port thread, and the -S magnet requirement.
Because the nominal stroke is 120mm, side-loading is less of a concern than with long-stroke actuators, but the 40mm rod diameter still handles substantial lateral stress. Remember that the rear adjuster only sets the travel end; for load-holding without live air pressure, 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 SAIJ160BX120-100S FAQ
The rear adjuster acts as a mechanical stop that lets you trim the effective stroke within a 20-120mm usable travel window. It fine-tunes the end position at commissioning but does not lock the load without continuous air pressure.
