About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X400-10
The AirTAC SAIJ200X400-10 is a double-acting ISO 15552 profile cylinder equipped with a rear mechanical adjuster, enabling you to fine-tune the end-of-travel position. With a nominal 400 mm stroke and a 10 mm adjustment range, it provides a usable travel window of 390 to 400 mm.
The extruded aluminum barrel features dual sensor grooves, and the carbon steel piston rod utilizes an M36x2 thread to handle substantial loads. Because the stroke reaches 400 mm, the large 40 mm rod diameter helps manage deflection, though an external guide is still recommended for unsupported lengths. The rear stopper acts purely as a travel limit and does not hold the load without continuous 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 SAIJ200X400-10 Is Used
Heavy Press Tuning
Dial in the exact bottom position of a large forming press within a 390-400 mm window to accommodate material thickness variations without changing tooling.
Pallet Changeover
Adjust the rear stopper by up to 10 mm during product size changeovers on a heavy-duty pallet handling line to set new end-of-stroke limits quickly.
Large Assembly Setup
Fine-tune the extension end position during the commissioning of large-scale automated assembly equipment to align heavy components perfectly.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X400-10 the Right Cylinder?
The 10 mm adjustable window is highly useful for dialing in exact end positions during machine commissioning or product changeovers, avoiding the need to physically swap out a fixed-stroke SAI cylinder. For a direct ISO 15552 replacement, match the 400 mm stroke, 10 mm adjuster, PT tapered port thread, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting format. Since the 400 mm stroke is substantial, ensure external linear guides are used to prevent excessive side-loading on the rod. If the machine requires true load-holding without live air pressure, a standard SAIJ will not suffice; consider an AirTAC SAIL or BSAI locking cylinder instead.
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 SAIJ200X400-10 FAQ
At the maximum pressure of 1.0 MPa, it delivers up to 3204 kgf.
The rear adjuster screw allows you to shorten the 400 mm nominal stroke by up to 10 mm, creating a 390-400 mm travel window. This stopper only sets the end position; it does not lock the load without live air pressure.
