About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX650-30S
The AirTAC SAIJ100X650-30-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 650 mm nominal stroke that can be fine-tuned down by up to 30 mm, yielding a usable travel window of 620-650 mm. This allows precise end-position calibration during commissioning without swapping hardware.
Built with an SUS420J2 stainless steel rod (code A) and PT tapered ports, this model includes a magnet (-S) for position sensing. The extruded aluminum barrel integrates sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic solid-state switches. Mounting options include 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 SAIJ100AX650-30S Is Used
Product Changeover
Dial in the 620-650 mm stroke window during format size changes on packaging lines without replacing the cylinder.
End-Stop Calibration
Fine-tune the retract position during machine commissioning to achieve exact mechanical placement without external shims.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX650-30S the Right Cylinder?
The adjustable 620-650 mm travel window is ideal for product changeovers, letting you dial in the exact retract stop without adding external stops. For a fixed end position, a standard SAI cylinder is simpler, but SAIJ excels where mechanical fine-tuning is required.
Because the 650 mm stroke is long, an external guide is recommended to handle side loads, as even the 25 mm rod and M20x1.5 thread have limits under leverage. The rear adjuster acts purely as a travel stop and does not hold the load without live air; for fail-safe load holding, consider an AirTAC SAIL or BSAI cylinder. This unit is dimensionally interchangeable per ISO 15552.
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 SAIJ100AX650-30S FAQ
At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster screw allows you to shorten the 650 mm nominal stroke by up to 30 mm, creating a 620-650 mm travel window. It functions as a mechanical stop and does not lock the load without air pressure.
