About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX325-30
The AirTAC SAIJ100X325-30 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 325 mm stroke that can be fine-tuned backward by up to 30 mm, yielding a precise 295-325 mm usable travel window.
This variant features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and utilizes PT tapered port threads (G1/2). The extruded aluminum barrel includes sensor grooves on both sides, allowing for straightforward position monitoring when paired with AirTAC CMSE reed or DMSE electronic sensors, though this specific SKU is configured without a magnet.

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 SAIJ100AX325-30 Is Used
Machine Setup Changeover
Dial in the 295-325 mm travel window during product family changeovers to perfectly seat components without repositioning physical hard stops.
Variable End-Stop Positioning
Trim the retract stroke by up to 30 mm on the fly to accommodate varying package sizes or pusher distances on a packaging line.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX325-30 the Right Cylinder?
If you need less force, stepping down to an 80 mm bore yields 2513 N; stepping up to 125 mm provides 6136 N. The integrated rear adjuster allows you to trim the stroke by up to 30 mm without swapping out the cylinder, unlike a fixed-stroke SAI model.
Because the stroke is 325 mm, an external guide is recommended to prevent excessive side-loading on the rod. For dimensionally interchangeable ISO 15552 replacements, match the 100 mm bore, 325 mm stroke, 30 mm adjustment, PT G1/2 port, and standard mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, consider an external rod lock or the SAIL/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 SAIJ100 Adjustable Cylinder SAIJ100AX325-30 FAQ
At 0.7 MPa, the push force increases to 5497 N.
The rear adjusting screw acts as a stopper that lets you shorten the effective stroke from the nominal 325 mm down to 295 mm. It allows precise end-position tuning at commissioning without needing to replace the cylinder or add external stops.
