About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX325-10S
The AirTAC SAIJ100X325-10-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. The built-in -10 mm adjustment screw allows you to fine-tune the effective travel within a 315-325 mm window, providing exact end-position calibration without needing external stops.
This variant features an SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. It utilizes PT tapered port threads (G1/2) and relies on adjustable air cushions at both ends to decelerate the load smoothly. Remember that the rear adjuster acts only as a travel stop and does not hold the load without continuous air pressure.

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 SAIJ100AX325-10S Is Used
Precision End-Stop Tuning
Dial in the exact 315-325 mm retraction point during machine commissioning to achieve perfect seating pressure without machining custom spacers.
Product Size Changeovers
Quickly adjust the stroke by up to 10 mm on a packaging line to accommodate slightly different carton lengths without changing the cylinder.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX325-10S the Right Cylinder?
If you need less force, stepping down to an 80 mm bore yields 2513 N at 0.5 MPa, whereas moving up to a 125 mm bore provides 6136 N. The adjustable 315-325 mm travel window is perfect for machine setups requiring micro-adjustments during commissioning or product changeovers, eliminating the need to swap out a fixed-stroke SAI cylinder.
Because this model features a 325 mm stroke, the 25 mm rod diameter should be paired with an external guide to prevent excessive side-loading and premature seal wear. To achieve direct compatibility during an ISO 15552 replacement, match the 100 mm bore, 325 mm stroke, -10 adjustment, PT port threads, and the -S magnet. The available mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options. For applications requiring the load to be held without live air pressure, consider the SAIL or BSAI series, as this cylinder's adjuster is strictly a stop.
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 SAIJ100AX325-10S FAQ
The rear adjusting screw acts as a mechanical stopper that lets you shorten the effective stroke by up to 10 mm. This creates a usable travel window of 315 to 325 mm, allowing you to fine-tune the end position at commissioning. The adjuster is a stop, not a lock, and cannot hold the load without live air pressure.
If you increase the pressure to 0.7 MPa, the push force rises to 5497 N.
