About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X260-75S
The AirTAC SAIJ200X260-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 185 to 260 mm usable travel window, letting you dial back the nominal 260 mm stroke by up to 75 mm during commissioning without adding external stops. It delivers massive thrust, pushing 15708 N and pulling 15080 N at 0.5 MPa, making it ideal for heavy-duty operations.
This unit includes a -S magnet for CMSE reed and DMSE electronic sensors, which seat neatly into the dual-side sensor grooves on the extruded aluminum barrel. The robust 40 mm carbon steel rod and M36x2 thread handle significant side loads, while the PT tapered port threads ensure a tight pneumatic connection. It features adjustable air cushions at both ends to manage heavy end-of-stroke kinetic energy.

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 SAIJ200X260-75S Is Used
Heavy Press Tuning
Dial in the exact 185 to 260 mm travel window during machine setup to accommodate varying material thicknesses in large-scale metal forming presses.
Product Changeover Stops
Adjust the retract end-position on the fly when switching between different pallet sizes on a heavy-duty packaging conveyor line.
Assembly Line Calibration
Fine-tune the end stopper during commissioning to perfect the seating force of large automotive components without adding external mechanical stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X260-75S the Right Cylinder?
The SAIJ rear adjuster acts purely as a mechanical travel stop; it cannot hold a load without live air pressure. For true fail-safe load holding, consider the SAIL or BSAI locking cylinders instead.
Because the 260 mm stroke is substantial, always pair this cylinder with an external guide to prevent rod binding and premature seal wear. This SAIJ model supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options. It operates at speeds of 30-500 mm/s and is dimensionally interchangeable per ISO 15552 standards.

- ✓ 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 SAIJ200X260-75S FAQ
At the maximum operating pressure of 1.0 MPa, it delivers up to 3204 kgf.
The rear adjusting screw allows you to mechanically shorten the 260 mm nominal stroke by up to 75 mm, creating a usable travel window of 185 to 260 mm. This stopper only sets the end position and does not lock the load without live air pressure.
