About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX425-30S
The AirTAC SAIJ100X425-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel by up to 30 mm, creating a precise 395-425 mm usable window for commissioning. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
This model utilizes PT tapered ports and a robust M20x1.5 rod thread to handle demanding setups. Because the stroke reaches 425 mm, the 25 mm rod diameter provides necessary rigidity, though an external guide remains essential to prevent excessive side-loading on long unsupported travels.

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 SAIJ100AX425-30S Is Used
Product Changeovers
Dial in the 395-425 mm stroke window during line format changes to accommodate different package lengths without physically replacing the cylinder.
End-Stop Tuning
Fine-tune the retract position at commissioning using the rear screw, ensuring precise alignment of heavy 100 mm bore tooling without external shims.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX425-30S the Right Cylinder?
The adjustable stroke is ideal for product changeovers, letting you fine-tune the end position without swapping hardware or adding external stops. For fixed-position tasks without variation, a standard SAI cylinder suffices.
When integrating this cylinder, note the rear adjuster acts strictly as a travel stop for deceleration, not a lock. It cannot hold a load without live air pressure. For secure load-holding, consider an AirTAC SAIL or BSAI cylinder. This SKU uses the SAIJ mounting subset (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR mounts.

- ✓ 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 SAIJ100AX425-30S FAQ
At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster screw lets you shorten the 425 mm nominal stroke by up to 30 mm, providing a usable travel range of 395 to 425 mm. It acts as a physical stop to set the end position and does not lock the load without air pressure.
