About the Airtac SAIJ125 Adjustable Cylinder SAIJ125X110-100S
The AirTAC SAIJ125X110-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 6136N of push force at 0.5 MPa. 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.

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.
High-Force Changeover Actuation
Leverage the 6136N thrust capacity for pressing or clamping different parts while adjusting the travel limit to match each specific component.
Is the Airtac SAIJ125 Adjustable Cylinder SAIJ125X110-100S the Right Cylinder?
Choose this 125mm bore variant when your application demands high thrust (6136N push at 0.5 MPa) alongside extensive on-the-fly stroke tuning. 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.
