About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX400-30S
The AirTAC SAIJ100X400-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that lets you dial back the nominal 400 mm travel by up to 30 mm, yielding a precise 370-400 mm usable window. The barrel is extruded aluminum with sensor grooves on both sides, not a tie-rod design.
This specific configuration includes a SUS420J2 stainless steel piston rod for superior corrosion resistance and a PT tapered port thread. The built-in magnet (-S) supports position sensing with AirTAC CMSE reed or DMSE electronic switches. The rear adjuster acts purely as a mechanical stop for end-position tuning and does not lock the load without 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 SAIJ100AX400-30S Is Used
Precision End-Stop Tuning
Dial in the exact 370-400 mm travel window during machine commissioning to perfect part ejection without adding external stopper blocks.
Product Changeover Lines
Quickly adjust the retract position by up to 30 mm to handle varying package sizes on a conveyor without changing out the cylinder.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX400-30S the Right Cylinder?
Select this 100 mm bore when you need heavy thrust that exceeds the 63 mm class (1559 N at 0.5 MPa) but want to avoid the larger 160 mm frame. The adjustable 370-400 mm window is ideal for machine setups requiring fine end-stop tuning during commissioning or product changeover without swapping cylinders. For load-holding without continuous air pressure, use an external rod lock or pilot-operated check valve, as the SAIJ adjuster is not a brake.
Because the 400 mm stroke is substantial, the 25 mm rod diameter should still be guided externally to prevent side-load damage on the seals. This SAIJ model is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). It is a direct replacement for ISO 15552 cylinders such as SMC CDQ2B100 and Festo DNC.

- ✓ 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 SAIJ100AX400-30S FAQ
The rear adjusting screw acts as a mechanical stop, allowing you to trim the effective stroke by up to 30 mm from the 400 mm nominal length. This creates a 370-400 mm usable travel window for fine-tuning end positions at commissioning.
At 0.9 MPa, the push force increases to 7068 N.
