About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X700-40S
The AirTAC SAIJ200X700-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 660 to 700 mm. As an extruded aluminum profile cylinder, it is dimensionally interchangeable with ISO 15552 cylinders such as Festo or SMC without relying on tie-rod construction.
This model includes a standard magnet for position sensing, working seamlessly with AirTAC CMSE reed switches or DMSE electronic solid-state sensors in the dual side sensor grooves. The PT tapered port threads and robust 40 mm carbon steel rod ensure high structural integrity. The rear mechanical stopper allows precise end-position tuning during commissioning without adding external stops, though it acts purely as a travel limit and not a load-holding lock.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15080 N | 15080 N |
| 0.7 MPa | 21111 N | — |
| Max (@1.0 MPa) | 3075 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 SAIJ200 Adjustable Cylinder SAIJ200X700-40S Is Used
Heavy-Duty Press Tuning
Dial in the exact 660-700 mm pressing depth during setup using the rear adjuster, accommodating material thickness variations without swapping cylinders.
Large Assembly Changeover
Adjust the retract end-position by up to 40 mm on the fly to handle different product sizes running down the same heavy-assembly line.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X700-40S the Right Cylinder?
Selecting this 200 mm bore cylinder is ideal when an application requires the maximum standard thrust class—up to 28274 N at 0.9 MPa—combined with on-the-fly stroke trimming. The 40 mm adjustment range is specifically valuable for product changeovers where the exact end-of-stroke contact point varies by 40 mm or less.
Because the 700 mm stroke is substantial, the heavy 40 mm rod diameter handles significant side loads, yet an external guide rail is still recommended to prevent rod bending over long unsupported travel. To replace this cylinder on an ISO 15552 machine, match the 200 mm bore, 700 mm stroke, 40 mm adjustment, G3/4 PT port, and the -S magnet. Note that the SAIJ mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options. For applications requiring the load to be held without continuous live air pressure, a plain SAIJ is insufficient; consider an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder instead.

- ✓ 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 SAIJ200 Adjustable Cylinder SAIJ200X700-40S FAQ
The rear adjusting screw acts as a mechanical stopper that allows you to shorten the effective stroke by up to 40 mm, creating a usable travel window of 660 to 700 mm. This stopper only sets the travel end and does not lock or hold the load without continuous air pressure.
