About the Airtac SAIJ125 Adjustable Cylinder SAIJ125X110-100S
By integrating a 100mm adjustment mechanism onto a 110mm nominal stroke, this unit provides a highly flexible 10 to 110mm usable travel window. This wide range is ideal for machinery that requires significant product-size changeovers without physically swapping out the actuator.
It features a carbon steel piston rod and a PT tapered port thread. Equipped with a magnet (-S), it supports AirTAC CMSE reed and DMSE electronic sensors for precise end-position detection. The extruded aluminum barrel includes sensor grooves on both sides, and the adjustable rear stopper acts purely as a travel end-limit, not a load-holding lock.

Theoretical Output Force (Ø125mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 5734 N | 5734 N |
| 0.7 MPa | 8027 N | — |
| Max (@1.0 MPa) | 1169 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 SAIJ125 Adjustable Cylinder SAIJ125X110-100S Is Used
Variable End-Stop Configuration
Dial the stroke back from 110mm down to 10mm to accommodate rapid changes in product dimensions on the same production line.
Machine Setup Commissioning
Fine-tune the exact retract position during initial machine build without adding external physical stops or shims.
Is the Airtac SAIJ125 Adjustable Cylinder SAIJ125X110-100S the Right Cylinder?
If your force requirements are lower, stepping down to a 100mm bore yields 3927N at the same pressure. The 100mm adjuster is selected over a fixed SAI cylinder when you need to dial in a highly variable end-stop during commissioning or product changeovers. For any load-holding requirements without live air pressure, note that this adjuster is only a stop; you should utilize an SAIL or BSAI cylinder instead. Because the usable travel can be dialed down to 10mm, ensure your external guiding handles the resulting geometry to prevent side-load damage.
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.
