About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX950-30S
The AirTAC SAIJ100X950-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 920 to 950 mm usable travel window. The extruded aluminum barrel includes sensor grooves on both sides, and the -S magnet supports position detection.
This specific SKU is equipped with a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance. The rear adjustment screw acts purely as a travel stop to fine-tune the retract end-position during commissioning; it does not lock or hold the load without live air pressure. For load-holding requirements without continuous air, consider the SAIL or BSAI series.

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 SAIJ100AX950-30S Is Used
Machine Changeover
Dial in the 920-950 mm retract position during product size transitions without adding external mechanical stops.
Variable End-Stop Diverter
Fine-tune the stroke end-position on a long-travel sorting diverter to accommodate varying package lengths.
Long-Stroke Press Setup
Adjust the bottom dead center on a 950 mm press operation during initial commissioning to perfect the working distance.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX950-30S the Right Cylinder?
Choose this adjustable-stroke model over a fixed SAI cylinder when your machine setup requires variable end-stops or precise product-changeover tuning without physically swapping the actuator. If your application requires less thrust, stepping down to a 63 mm bore yields 1559 N at 0.5 MPa. Stepping up to a 125 mm bore provides 6136 N at 0.5 MPa.
Because the 950 mm stroke is substantial, the 25 mm rod diameter and M20x1.5 thread will still experience deflection under high side-loads; an external guide rail is strongly recommended to prevent premature seal wear. This cylinder is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, CR). The -S magnet works seamlessly with AirTAC CMSE reed and DMSE electronic solid-state sensors.

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 SAIJ100AX950-30S FAQ
At the maximum 1.0 MPa pressure, it delivers 801 kgf of push force.
The rear adjuster screw allows you to shorten the effective travel by up to 30 mm, creating a 920 to 950 mm adjustable window. It functions as a mechanical stop to fine-tune the end position and does not hold the load without live air pressure.
