About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX425-10S
The AirTAC SAIJ100X425-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 415-425mm.
This configuration features a SUS420J2 stainless steel rod for enhanced corrosion resistance and PT tapered ports. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet (-S) directly supports AirTAC CMSE reed and DMSE electronic solid-state switches for exact position feedback.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
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 SAIJ100AX425-10S Is Used
Precision End-Stop Tuning
Dial in the exact 415-425mm retract position during machine commissioning to perfect material seating without adding external stopper blocks.
Product Changeover
Quickly adjust the stroke end by up to 10mm on the production line to accommodate slight variations in incoming part sizes.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX425-10S the Right Cylinder?
The 10mm rear adjuster acts purely as a mechanical stop to fine-tune the retract position, meaning it cannot hold the load dynamically without live air—true load-holding requires a SAIL or BSAI variant. Because the 425mm stroke is relatively long, an external guide is recommended to prevent excessive rod side-loading.
For a true ISO 15552 replacement match, verify the 100mm bore, 425mm nominal stroke, 10mm adjustment, PT port thread, and the -S magnet option. SAIJ supports a specific mounting subset including Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR mounts.
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 SAIJ100AX425-10S FAQ
At 0.7MPa, the push force increases to 5497N.
The rear adjuster screw allows you to shorten the 425mm nominal stroke by up to 10mm, creating a 415-425mm travel window. It functions as a mechanical stop and does not lock the load without live air pressure.
