About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX25-10
The AirTAC SAIJ100X25-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering robust thrust for medium-to-heavy pneumatics. This yields a highly precise 15-25mm usable travel window, ideal for dialing in exact end-positions during commissioning without swapping out the entire unit.
Built with a SUS420J2 stainless steel rod (option A) and PT tapered port threads, this 100mm bore model handles demanding environments while resisting corrosion. The extruded aluminum barrel features dual-side sensor grooves ready for CMSE reed or DMSE electronic switches if a magnet is added later. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options found on some standard variants.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 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 SAIJ100 Adjustable Cylinder SAIJ100AX25-10 Is Used
Machine Setup Tuning
Dial in the exact 15-25mm travel window during initial commissioning to perfect pressing or clamping depth without adding external physical stops.
Product Changeover
Quickly adjust the end-position by a few millimeters on a packaging line when switching to a different product size or thickness.
Assembly Station Calibration
Fine-tune the stroke on automated assembly lines to compensate for mechanical wear or material tolerances over the machine's lifespan.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX25-10 the Right Cylinder?
Choose this 100mm bore adjustable-stroke cylinder when an application requires substantial force but exact end-position tuning is critical at startup or during product changeover. The rear adjuster acts purely as a mechanical stop to trim the travel window; it does not hold the load without live air pressure. For true load-holding requirements, consider the SAIL or BSAI series instead.
When replacing an ISO 15552 cylinder, match the 100mm bore, 25mm stroke, 10mm adjustment range, PT port thread, and required mounting accessory. Because the stroke is short, side-loading is minimal, but ensure the load is guided to prevent binding. The dual air cushions at both ends decelerate the piston smoothly within the adjusted travel range.
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 SAIJ100 Adjustable Cylinder SAIJ100AX25-10 FAQ
The pull force is 3681N at 0.5 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 25mm nominal stroke by up to 10mm. This creates a 15-25mm usable travel window for fine-tuning the end position.
