About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX425-100S
The AirTAC SAIJ100X425-100-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. The barrel is extruded aluminum with sensor grooves on both sides, and this -S variant includes a magnet for CMSE reed and DMSE electronic solid-state switches.
This model uses an SUS420J2 stainless steel rod (code A) for improved corrosion resistance and features PT tapered port threads with a G1/2 port size. Because the nominal stroke is 425 mm, the 25 mm rod diameter should be paired with an external guide to prevent excessive side-loading on the piston. The rear adjuster acts purely as a mechanical stop to set the retract position; it does not lock or hold the load without continuous live 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 SAIJ100AX425-100S Is Used
Product Changeovers
Dial in the exact 325-425 mm retract distance during format size changes without physically replacing the cylinder or bolting on external stops.
Machine Setup
Fine-tune the end-of-stroke position at commissioning to perfectly align heavy 100 mm bore tooling, absorbing mechanical variance across the fixture.
Variable End Stops
Provide a flexible mechanical stop for automated lines processing different material lengths, using the 100 mm trim window to adapt on the fly.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX425-100S the Right Cylinder?
The 100 mm adjustment range is ideal for machinery requiring frequent product-size changeovers, allowing operators to dial in the exact retract distance without swapping cylinders or adding external stops. For load-holding without live air pressure, select a SAIL pneumatic lock or BSAI clamp-lock cylinder, as the SAIJ adjuster is only a travel stop. Ensure your ISO 15552 replacement matches the 425 mm stroke, 100 mm adjustment, PT ports, SUS420J2 rod, and -S magnet. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ100AX425-100S FAQ
If pressure is increased to 0.9 MPa, the push force reaches 7068 N.
The rear adjuster allows you to shorten the 425 mm nominal stroke by up to 100 mm, giving an effective travel window of 325-425 mm. It functions as a mechanical stop to fine-tune the retract position and does not lock the load without live air.
