About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X25-10S
The AirTAC SAIJ200X25-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 200mm bore and a 25mm nominal stroke, dialed back by up to 10mm to provide a precise 15-25mm usable travel window.
This model includes a magnetic piston (-S) for position detection and uses a standard carbon steel rod. The extruded aluminum barrel incorporates sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic solid-state switches. Because the rear adjuster acts solely as a mechanical stop to set the travel end, it does not hold the load without live air pressure.

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 SAIJ200X25-10S Is Used
Heavy-Duty Press Tuning
Dial in the exact 15-25mm travel window during machine commissioning to apply 15708N of clamping force without adding external mechanical stops.
Product Size Changeover
Quickly adjust the rear stopper by up to 10mm to accommodate slightly different workpiece heights on a high-force assembly line.
End-Position Calibration
Fine-tune the retract end position on heavy machinery to perfect the timing and mechanical interface without disassembling the cylinder.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X25-10S the Right Cylinder?
Select this 200mm bore adjustable-stroke cylinder when an application requires extreme force combined with exact end-position tuning during commissioning, avoiding the need to add external stops or swap cylinders for minor product changes. If the full 25mm stroke is required without trimming, a fixed-stroke SAI cylinder is the simpler choice. For applications needing fail-safe load holding without continuous air pressure, consider the SAIL air-released lock or BSAI clamp-lock series instead.
When matching this ISO 15552 cylinder for a retrofit, verify the 200mm bore, 25mm stroke, 10mm adjustment range, PT tapered port thread, and the -S magnet requirement. It uses a robust 40mm diameter carbon steel rod with an M36x2 thread; however, for any stroke of 300mm or more, an external guide is recommended to prevent excessive side-load wear.
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 SAIJ200X25-10S FAQ
At the maximum operating pressure of 1.0 MPa, it delivers up to 3204 kgf of thrust.
The rear adjuster acts as a mechanical stop that trims the 25mm nominal stroke back by up to 10mm, creating a 15-25mm usable travel window. It only sets the travel end and does not lock or hold the load without live air pressure.
