About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X350-75
The AirTAC SAIJ200X350-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. This creates a precise 275-350mm usable travel window for heavy-duty positioning without adding external stops.
The extruded aluminum barrel includes dual sensor grooves, and the carbon steel rod uses an M36x2 thread with a G3/4 PT port. The rear adjuster acts purely as a mechanical stop to fine-tune the retract end position during commissioning. It is not a locking device, so you must maintain live air pressure to hold the load.

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 SAIJ200X350-75 Is Used
Heavy Press Tonnage
Delivers up to 3204 kgf clamping force for large metal forming or heavy assembly presses.
Pallet Size Changeover
Dial the 75mm adjustment screw to reposition the end stop for varying pallet lengths on a heavy-duty conveyor.
Large Fixture Alignment
Fine-tune the 275-350mm travel window during machine setup to perfectly align large automated welding fixtures.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X350-75 the Right Cylinder?
The 75mm adjustment range is ideal for large product size changeovers on a line, letting you set a new end position without swapping the cylinder. For fixed stops without the need for commissioning tweaks, a standard SAI cylinder is sufficient.
Because the 350mm stroke is substantial and the rod is heavy, you must use an external guide to prevent excessive side-load wear. This cylinder uses a reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. It operates at 30-500mm/s. If you need true load-holding without live air, use a SAIL pneumatic lock or BSAI clamp-lock cylinder instead of relying on the adjuster.
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 SAIJ200X350-75 FAQ
At the maximum 1.0MPa pressure, the push force reaches 28274N.
The rear adjuster screw lets you mechanically shorten the 350mm stroke anywhere down to 275mm. This creates a flexible travel window for setting exact end positions during machine commissioning, but it acts only as a stop and does not lock the load without air pressure.
