About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X325-10S
The AirTAC SAIJ200X325-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers massive thrust, pushing 28274N at 0.9 MPa, making it suited for heavy-duty industrial handling. The integrated -S magnet supports position detection via CMSE reed and DMSE electronic sensors.
This model provides a usable travel window of 315 to 325 mm, letting you dial back the nominal stroke by up to 10 mm. It uses a PT tapered port and a robust 40 mm carbon steel rod with an M36x2 thread. Because the 325 mm stroke is long relative to the 40 mm rod, an external guide is recommended to manage side loads.

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 SAIJ200X325-10S Is Used
Heavy Press Tuning
Fine-tune the 315 to 325 mm travel window during heavy press commissioning to achieve exact end-position contact without re-engineering the machine frame.
Large Fixture Changeover
Adjust the retract stop by up to 10 mm when swapping large production fixtures, ensuring the new tooling clears the workpiece safely.
Automated Assembly End-Stop
Set precise retract limits on automated assembly lines handling heavy payloads, relying on the 40 mm rod and M36x2 thread for robust actuation.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X325-10S the Right Cylinder?
The 10 mm rear adjuster is ideal for fine-tuning the retract end position during commissioning without swapping the cylinder or adding external stops, unlike a fixed-stroke SAI.
When replacing an ISO 15552 cylinder, match the 200 mm bore, 325 mm stroke, 10 mm adjustment, PT port, and the -S magnet requirement. Mounting uses the reduced SAIJ set: Basic, FA, LB, TC, FTC, TCM1, and TCM2. Remember that the rear adjuster acts only as a travel stop; it does not hold the load without live air. For true load-holding, use an external rod lock or a SAIL/BSAI cylinder.
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 SAIJ200 Adjustable Cylinder SAIJ200X325-10S FAQ
The maximum force at 1.0 MPa is 3204 kgf.
The rear adjuster screw lets you shorten the effective stroke by up to 10 mm, creating a usable travel window of 315 to 325 mm. This stopper allows precise end-position tuning during setup but does not lock or hold the load without continuous air pressure.
