About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX125-30S
The AirTAC SAIJ160X125-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 95 to 125 mm for precise end-position tuning. The extruded aluminum barrel features sensor grooves on both sides, and the integrated -S magnet enables position detection via AirTAC CMSE reed or DMSE electronic solid-state switches.
This model utilizes PT tapered port threads (G3/4) and includes variable air cushions at both ends to manage deceleration. The rear adjuster functions strictly as a travel stop, meaning it cannot hold a load without continuous live air pressure. For load-holding requirements without pneumatic pressure, external pilot-operated check valves or dedicated locking cylinders like the SAIL or BSAI series are required.

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 SAIJ160BX125-30S Is Used
Press Stroke Calibration
Dial in the exact 95 to 125 mm end-stop during machine commissioning to accommodate varying material thicknesses without swapping out the entire actuator.
Stainless Rod Actuation
Utilize the SUS304 rod material in environments requiring high corrosion resistance, ensuring reliable positioning feedback via the integrated magnet and DMSE sensors.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX125-30S the Right Cylinder?
The adjustable stroke is chosen over a fixed-stroke SAI cylinder when machine setups require variable end-stops or fine-tuning during commissioning without adding external stopper hardware. The SUS304 rod offers superior corrosion resistance compared to standard carbon steel, making it suitable for harsher environments.
To match this exact configuration as an ISO 15552 replacement, specify a 160 mm bore, 125 mm stroke, 30 mm adjustment range, PT port threads, and the -S magnet option. The mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 accessories, deliberately omitting FB, CA, CB, and CR brackets. Because the nominal stroke of 125 mm is below the 300 mm threshold, external side-load guides are less critical, though the robust 40 mm rod diameter naturally handles high axial and moderate side loads.

- ✓ 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 SAIJ160BX125-30S FAQ
At the maximum rated pressure of 1.0 MPa, it can deliver up to 2050 kgf.
The rear adjuster screw acts as a mechanical stop, allowing you to trim the effective travel back by up to 30 mm. This creates a usable stroke window of 95 to 125 mm. It only sets the end position and does not lock the load without live air pressure.
