About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX120-75S
The AirTAC SAIJ160X120-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 45 to 120 mm, allowing you to dial back the 120 mm nominal stroke by up to 75 mm. This bore delivers 10053 N of pull force at 0.5 MPa, making it suited for heavy-duty positioning tasks.
This variant includes a SUS304 stainless steel rod for corrosion resistance and a -S magnet for electronic DMSE or reed CMSE switches. The extruded aluminum barrel carries sensor grooves on both sides, and the rear adjuster acts purely as a travel stop for commissioning, not a load-holding lock.

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 SAIJ160BX120-75S Is Used
Variable End-Stop Tuning
Dial in the exact retract distance between 45 and 120 mm during machine commissioning to accommodate varying material thicknesses on the fly.
Product Size Changeovers
Rapidly adapt heavy-duty press or lift stations to new product dimensions by adjusting the rear stopper screw instead of replacing the entire actuator.
Actuator Setup Calibration
Achieve precise end-of-stroke positioning for heavy fixtures without bolting on external physical stops or modifying the machine frame.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX120-75S the Right Cylinder?
Choose this adjustable-stroke model when you need to fine-tune the retract end position during machine setup or product changeover without swapping cylinders or adding external stops. If you need less force, stepping down to a 125 mm bore yields 5734 N of pull at 0.5 MPa. For load-holding without live air pressure, this cylinder is insufficient because the adjuster is only a stop; you would need an SAIL air-released lock or a BSAI clamp-lock cylinder instead.
To replace an ISO 15552 cylinder, match the 160 mm bore, 120 mm stroke, PT tapered G3/4 port, and the -S magnet. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the 120 mm stroke is relatively short for this large bore, side-loading is less severe than in longer strokes, but the 40 mm rod and M36x2 thread still handle high bending moments well.
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 SAIJ160BX120-75S FAQ
The rear adjuster screw lets you shorten the 120 mm nominal stroke by up to 75 mm, creating a usable travel window of 45 to 120 mm. This stopper only sets the end position; it does not lock the load without live air pressure.
