About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX650-40S
The AirTAC SAIJ100X650-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 610 to 650 mm.
This variant features a SUS420J2 stainless steel rod for enhanced corrosion resistance and includes a magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic sensors. It uses PT tapered ports and supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.

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 SAIJ100AX650-40S Is Used
Variable End-Stop Machining
Dials in the exact 610 to 650 mm retract position during machine setup, allowing operators to fine-tune part clamping without adding external mechanical stops.
Heavy Assembly Pressing
Provides consistent pressing force at variable depths, using the rear adjuster to set the precise bottoming-out point for different assembly heights.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX650-40S the Right Cylinder?
Select this 100 mm bore cylinder when an application demands high thrust combined with variable end-stops, such as accommodating product size changes on a line. Because the stroke is 650 mm, an external guide is recommended to manage side-load on the extended rod.
The rear screw acts purely as a travel stop for the retract end, not a lock, meaning it cannot hold a load without live air. For applications requiring true load-holding without pneumatic pressure, consider the SAIL or BSAI variants. To match this ISO 15552 interchangeable cylinder exactly, specify the 100 mm bore, 650 mm stroke, 40 mm adjustment, PT ports, and the -S magnet.
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 SAIJ100AX650-40S FAQ
At 0.5 MPa, the push force is 3927 N.
The rear adjuster allows you to shorten the nominal 650 mm stroke by up to 40 mm, creating a usable travel window of 610 to 650 mm. This stopper fine-tunes the end position but does not lock the load without live air pressure.
