About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX650-10S
The AirTAC SAIJ100X650-10-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 640-650 mm usable travel window, allowing you to dial back the stroke by up to 10 mm during commissioning without adding external stops.
This variant includes a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance and carries a magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides. The rear adjuster acts purely as a travel stop to set deceleration, meaning it will not hold a 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 SAIJ100AX650-10S Is Used
Machine Changeover
Dial in the 10 mm travel adjustment during product size transitions to set exact retract positions without physically swapping the cylinder.
Variable End Stops
Use the rear stopper to fine-tune the 640-650 mm travel window for multi-format packaging lines requiring precise end-of-stroke positioning.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX650-10S the Right Cylinder?
Choose this 100 mm bore when a 50 mm bore falls short on thrust, as the 50 mm version only yields 982 N at 0.5 MPa compared to this model's 3927 N. The adjustable stroke is ideal for fine-tuning end positions during machine setup or product changeover. For load-holding without continuous air pressure, this cylinder is insufficient; you should explore the SAIL (air-released lock) or BSAI (clamp-lock) series instead.
When replacing an ISO 15552 cylinder, verify the 100 mm bore, 650 mm stroke, 10 mm adjustment range, PT tapered ports, and the -S magnet requirement. Because the 650 mm stroke is long and the rod is 25 mm, an external guide is strongly recommended to prevent excessive side loading and rod deflection. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

- ✓ 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 SAIJ100AX650-10S FAQ
At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster screw lets you trim the effective travel from the 650 mm nominal stroke down to 640 mm. It functions as a mechanical stop to fine-tune the retract position, but it does not lock the load without live air pressure.
