About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX30-30S
The AirTAC SAIJ100X30-30-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. Outfitted with a SUS420J2 stainless steel rod (material code A) and a magnet for position sensing, it provides a 0-30 mm usable travel window from its 30 mm nominal stroke. This allows you to dial in the exact end-of-travel position during commissioning without adding external stops.
The rear adjuster functions strictly as a travel stop to decelerate the load alongside the variable air cushions at both ends, but it does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead. This model supports AirTAC CMSE reed and DMSE electronic sensors via the dual-side sensor grooves on its extruded aluminum barrel, and it uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ100AX30-30S Is Used
Machine Changeover
Dial in the exact end-stop during product size changeovers without physically replacing the cylinder or adding external mechanical stops.
End-Position Tuning
Fine-tune the 0-30 mm travel window at commissioning to perfectly align pressing or clamping forces within a compact assembly.
Variable End Stops
Adjust the retract position on the fly for automated lines that process parts of slightly varying lengths.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX30-30S the Right Cylinder?
Conversely, moving up to the 125 mm bore provides 6133 N. The SAIJ100X30-30-S is ideal over a fixed SAI cylinder when product changeovers require variable end-stops without swapping the actuator. Remember that the rear adjuster is a stop, not a lock; it will not maintain position without continuous air pressure.
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 SAIJ100AX30-30S FAQ
At 0.7 MPa, the push force increases to 5497 N.
The SAIJ100X30-30-S has a 30 mm nominal stroke with an adjustment range of 30 mm, giving it a usable travel window of 0-30 mm. A rear screw acts as a stop to mechanically limit the stroke, but it is not a lock and will not hold the load without live air pressure.
