About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X250-75S
The AirTAC SAIJ200X250-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 175 to 250 mm. The integrated -S magnet enables position sensing with AirTAC CMSE reed or DMSE electronic switches.
This heavy-duty actuator uses a 40 mm carbon steel rod with an M36x2 thread, paired with 50 mm air cushions at both ends to manage high kinetic energy. The extruded aluminum barrel includes sensor grooves on both sides, and the tapered PT ports ensure a tight pneumatic seal. The rear stopper allows precise end-position tuning without adding external physical stops.

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 SAIJ200X250-75S Is Used
Heavy Press Tuning
Dial in the exact 175-250 mm end-stop during heavy press commissioning to accommodate different material thicknesses without swapping actuators.
Product Changeover
Quickly adjust the retract distance up to 75 mm on automated assembly lines when switching between varying product sizes.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X250-75S the Right Cylinder?
If your load demands less force, stepping down to a 160 mm bore yields 10053 N at 0.5 MPa, which may reduce air consumption. The 75 mm adjustment range is particularly useful for fine-tuning the retract position during product changeovers. For load-holding without live air pressure, note that the rear adjuster functions only as a travel stop; you should integrate an external rod lock or pilot-operated check valve.
Because this cylinder features a 250 mm stroke, which is below the 300 mm threshold requiring external guidance, the 40 mm rod still handles substantial side loads. However, for any application exceeding 300 mm, an external guide is mandatory. This model is dimensionally interchangeable per ISO 15552 and uses the standard SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2. Ensure your setup matches the PT port thread and utilizes the -S magnet for CMSE or DMSE sensor compatibility.
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 SAIJ200X250-75S FAQ
At 0.7 MPa, the push force increases to 21991 N.
The rear adjuster acts as a mechanical stop, allowing you to shorten the effective stroke from its 250 mm nominal length down to 175 mm. It is a travel stop, not a lock, and does not hold the load without live air pressure.
