About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X270-75S
The AirTAC SAIJ200X270-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a usable travel window of 195 to 270 mm. The integrated -S magnet allows precise position detection using AirTAC CMSE reed and DMSE electronic sensors.
This adjustable variant allows operators to fine-tune the retract end-position during commissioning without adding external stops or swapping the cylinder. It features a robust 40 mm carbon steel rod with an M36x2 thread to manage high side loads, and utilizes PT tapered port threads for secure pneumatic connections. The rear adjuster acts purely as a travel stop for deceleration, meaning it will not hold the load without continuous 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 SAIJ200X270-75S Is Used
Heavy Press Tuning
Dial in the exact 195-270 mm retraction depth during heavy press commissioning to accommodate varying material thicknesses without external stopper hardware.
Product Size Changeover
Quickly adjust the end-stop on a conveyor sorting arm by up to 75 mm to handle different package dimensions on the fly.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X270-75S the Right Cylinder?
Selecting this 200 mm bore cylinder is ideal when your application requires extreme force alongside a variable end-stop. Here, the 75 mm adjustment range is specifically valuable for product-size changeovers on large production lines, allowing rapid recalibration of the stroke endpoint. Because the nominal stroke is 270 mm, you should ensure adequate external guiding to prevent excessive rod side-loading, even with the substantial 40 mm rod diameter. For load-holding without live air, this cylinder is insufficient; you must specify an external rod lock or pilot-operated check valve, or choose the SAIL or BSAI series instead. To match this ISO 15552 interchangeable cylinder, use a 200 mm bore, 270 mm stroke, 75 mm adjustment, PT G3/4 port, and a -S magnet.
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 SAIJ200X270-75S FAQ
At 0.5 MPa, the push force is 15708N and the pull force is 15080N. At 0.7 MPa, the push force increases to 21991N.
The rear adjuster screw allows you to shorten the effective travel from the nominal 270 mm down to 195 mm, providing a 75 mm window for fine-tuning the retract end-position during setup.
