Airtac SAIJ200 Adjustable Cylinder SAIJ200X700-20
The AirTAC SAIJ200 Adjustable Cylinder SAIJ200X700-20 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 700mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.

About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X700-20
The AirTAC SAIJ200X700-20 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 700 mm nominal stroke that can be fine-tuned backward by up to 20 mm, yielding a usable travel window of 680 to 700 mm. This allows precise end-position calibration at commissioning without swapping hardware.
The robust design incorporates a 40 mm carbon steel rod with an M36x2 thread, paired with 50 mm variable air cushions at both ends to manage heavy kinetic energy. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU omits the magnet, meaning CMSE or DMSE electronic switches cannot be used without a magnetic piston. Fluid must be filtered to 40 um, operating reliably between -20 and +70 C.

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 SAIJ200X700-20 Is Used
Heavy Press Tuning
Dial in the exact 680-700 mm pressing depth during machine commissioning without machining custom spacers for massive forming operations.
Large Assembly Changeover
Adjust the retract end-stop by up to 20 mm to accommodate product size variations on heavy-duty automotive assembly lines.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X700-20 the Right Cylinder?
Select this 200 mm bore actuator when an application requires extreme thrust combined with on-the-fly retract adjustments, such as pressing or heavy clamping tasks where a fixed 700 mm SAI cylinder would lack setup flexibility. When specifying the ISO 15552 replacement match, confirm the 700 mm stroke, the 20 mm adjustment range, PT tapered port threads, and the mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2).
Because this unit features a 700 mm stroke, the extended 40 mm rod is subject to significant side-loading risks; an external guide mechanism is strongly recommended to prevent premature seal wear. Furthermore, the rear adjuster acts strictly as a mechanical stop for deceleration and positioning, not as a locking device. The cylinder will not hold its load without live air pressure, so applications requiring true fail-safe load holding must utilize an external rod lock or explore the SAIL or BSAI cylinder variants.
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 SAIJ200X700-20 FAQ
At the maximum rated pressure of 1.0 MPa, it delivers a peak push force of 3204 kgf.
The rear adjuster screw allows you to shorten the 700 mm nominal stroke by up to 20 mm, creating a usable travel window of 680 to 700 mm. This stopper fine-tunes the end position but does not lock the load without continuous air pressure.
