About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX125-75S
The AirTAC SAIJ160X125-75-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. Equipped with a SUS304 stainless steel rod and a PT tapered port, it incorporates a magnet for position sensing.
This specific SKU provides a usable travel window of 50-125 mm. By turning the external rear stopper, technicians can fine-tune the retract end-position during commissioning or product changeovers without swapping the entire cylinder. The extruded aluminum barrel includes sensor grooves on both sides, allowing precise mounting of CMSE reed or DMSE electronic switches.

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 SAIJ160BX125-75S Is Used
Variable End-Stop Tuning
Dial in the retract position anywhere from 50 to 125 mm during machine setup, providing exact end-position tuning without machining external stop blocks.
Product Changeover Systems
Quickly adapt the cylinder's effective stroke on packaging or processing lines when switching to different product sizes, minimizing downtime.
High-Force Positioning
Leverage the 9425N pull force at 0.7 MPa to move heavy jigs or fixtures into precise retracted positions, guided by the integrated SUS304 stainless steel rod.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX125-75S the Right Cylinder?
The adjustable stroke is ideal for variable end-stops on machinery that processes different product sizes, offering a built-in tuning range instead of relying on a fixed-stroke SAI cylinder.
For an ISO 15552 replacement, match the 160 mm bore, 125 mm nominal stroke, 75 mm adjustment, PT port thread, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true fail-safe load holding, consider the SAIL or BSAI series.
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 SAIJ160BX125-75S FAQ
The rear adjusting screw acts as a mechanical stopper that lets you shorten the effective stroke by up to 75 mm. This creates a usable travel window between 50 and 125 mm, allowing fine-tuning of the retract position at commissioning without adding external stops.
At its maximum operating pressure of 1.0 MPa, the push force reaches 18095N.
