About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX125-100
The AirTAC SAIJ32X125-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the nominal 125 mm stroke by up to 100 mm, creating a 25-125 mm usable travel window for highly flexible end-position tuning. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE reed or DMSE electronic switches if a magnet is added later.
Because the adjuster acts purely as a mechanical stop at the retract end, it decelerates travel but does not lock the load without live air pressure. It shares the exact ISO 15552 mounting interface dimensions, making it dimensionally interchangeable with standard profile cylinders, and supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 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 Adjustable Cylinder SAIJ32 SAIJ32AX125-100 Is Used
Variable End-Stop Tuning
Dial in the exact retract position from 25 to 125 mm during machine commissioning without replacing the cylinder or adding external stopper blocks.
Product Size Changeover
Quickly adapt the stroke window on automated lines processing different product lengths, using the rear screw to set new end positions in seconds.
Corrosion-Resistant Actuation
Leverage the SUS420J2 stainless steel rod in light manufacturing or assembly stations where moisture or minor chemical exposure is a concern.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX125-100 the Right Cylinder?
Choose this 32 mm bore when an application requires a 25-125 mm variable end-stop for frequent product changeovers, rather than swapping a fixed-stroke SAI cylinder. To replace this ISO 15552 unit, match the 32 mm bore, 125 mm stroke, 100 mm adjustment, PT port threads, SUS420J2 rod, and no-magnet configuration.
For any stroke at or above 300 mm, an external guide is recommended to prevent side-loading damage, though this 125 mm unit is compact enough to manage shorter travel safely. Remember that for load-holding without continuous air pressure, this cylinder is insufficient; you must pilot an external rod lock or check valve, or select an AirTAC 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 Adjustable Cylinder SAIJ32 SAIJ32AX125-100 FAQ
At the maximum 1.0 MPa pressure, it achieves up to 82 kgf.
The rear adjuster screw acts as a mechanical stop that can trim the nominal 125 mm stroke back by up to 100 mm, providing a usable travel window of 25 to 125 mm. It sets the end position but does not hold the load without live air pressure.
