About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X550-100S
The AirTAC SAIJ200X550-100-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty tasks requiring exact end-position tuning. The integrated rear adjustment screw allows you to dial back the nominal 550mm stroke by up to 100mm, providing a highly flexible 450-550mm usable travel window for precise product changeovers without adding external stops.
This variant includes a magnet for position sensing and is fully compatible with AirTAC CMSE reed and DMSE electronic switches. It features PT tapered port threads (G3/4) and utilizes an extruded aluminum barrel with sensor grooves on both sides. Unlike fixed-stroke SAI units, this adjustable model allows seamless fine-tuning at commissioning. Remember, the rear adjuster acts strictly as a travel stop to decelerate the load, not as a lock to hold it statically without 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 SAIJ200X550-100S Is Used
Heavy Press Tuning
Dial in the exact 450-550mm travel window during heavy press commissioning to accommodate new tooling heights without swapping out the entire cylinder.
Variable Product Forming
Adjust the rear stopper on the fly for production lines running different material lengths, ensuring precise end-positioning across product changeovers.
Large Assembly Stops
Fine-tune the end-of-stroke deceleration for large assembly fixtures, using the 100mm adjustment range to perfect the mating of heavy components.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X550-100S the Right Cylinder?
If your force requirements are lower, stepping down to a 160mm bore yields 10053N at the same pressure, saving space and air volume. The 100mm adjustment range is ideal for machinery that processes varying product sizes, allowing operators to reconfigure the end-stop rapidly. For load-holding without continuous air pressure, this plain SAIJ is insufficient; consider the SAIL (air-released lock) or BSAI (clamp-lock) series instead.
When replacing an ISO 15552 cylinder, match these exact parameters: 200mm bore, 550mm nominal stroke, 100mm adjustment, PT port threads, and the -S magnet option. Because the 550mm stroke is substantial and the 40mm rod is heavy, long unsupported strokes demand an external guide to prevent side-load damage. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.

- ✓ 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 SAIJ200X550-100S FAQ
At the maximum operating pressure of 1.0 MPa, it delivers up to 3204 kgf.
The rear adjuster screw allows you to shorten the 550mm nominal stroke by up to 100mm, creating a usable travel window of 450-550mm. It functions as a mechanical stop to tune the end position and must not be used as a lock to hold loads without live air.
