About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X550-10
The AirTAC SAIJ200X550-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster, engineered to deliver massive thrust for heavy-duty pneumatics. An external adjusting screw at the rear allows you to shorten the effective travel, providing a 540-550mm usable stroke window for precise machinery setup without adding external stops.
This adjustable-stroke model retains the standard extruded aluminum barrel with dual sensor grooves but uses a specific mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2. It operates at speeds of 30-500mm/s and features PT tapered port threads (G3/4) alongside 50mm variable air cushions at both ends. The rear adjuster functions strictly as a travel stop to decelerate the load, not as a lock, meaning it cannot hold a position 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 SAIJ200X550-10 Is Used
Heavy Press Tuning
Dial in the exact 540-550mm end-stop during press commissioning to accommodate material thickness variations without swapping out the entire cylinder.
Product Line Changeover
Quickly adjust the retract position on heavy manufacturing lines when switching between product sizes, using the rear stopper to set new boundaries.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X550-10 the Right Cylinder?
The 10mm adjustment range is ideal for fine-tuning the retract end-position during commissioning or product changeover, offering a distinct advantage over a fixed-stroke SAI cylinder when exact end-stop positioning is critical. For load-holding without continuous air pressure, this cylinder is insufficient; you must integrate an external rod lock or pilot-operated check valve, or select a SAIL or BSAI model. To replace this ISO 15552 cylinder, match the 200mm bore, 550mm stroke, 10mm adjustment, PT G3/4 port, and the correct mounting accessory. Because the 550mm stroke is long, an external guide is recommended to prevent rod side-loading and premature wear.
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 SAIJ200X550-10 FAQ
It features a rear adjusting screw that acts as a mechanical stop, allowing you to trim the nominal 550mm stroke back by up to 10mm. This creates a 540-550mm usable travel window for fine-tuning the end position at commissioning. The adjuster and air cushions only set the travel end and decelerate the load; they do not hold the load without live air.
It operates at a speed range of 30-500mm/s, suitable for heavy-duty industrial movements.
