About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X550-50
The AirTAC SAIJ200X550-50 is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 500-550 mm usable travel window, letting you dial back the 550 mm nominal stroke by up to 50 mm during commissioning.
This heavy-duty actuator uses a robust 40 mm carbon steel rod with an M36x2 thread, paired with 50 mm variable air cushions at both ends to manage high kinetic energy. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed or DMSE electronic switches. It supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ200X550-50 Is Used
Heavy Press Tuning
Fine-tune the 500-550 mm travel window on large pressing equipment to accommodate different material thicknesses without changing the cylinder.
Line Changeover
Adjust the retract end-stop during product size changeovers on heavy manufacturing lines, saving time by avoiding physical cylinder swaps.
Fixture Calibration
Dial in the exact end position for large machining fixtures, using the rear screw to compensate for mechanical wear over time.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X550-50 the Right Cylinder?
Choose this 200 mm bore model when your application requires extreme thrust, such as 15708 N at 0.5 MPa, and you need precise end-position tuning without swapping cylinders. The 50 mm rear adjuster acts purely as a travel stop to fine-tune the retract position; it does not lock or hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series.
To replace an ISO 15552 cylinder, match the 200 mm bore, 550 mm stroke, 50 mm adjustment, PT tapered port thread, and the appropriate mounting accessory. Because the 550 mm stroke is long and the 40 mm rod carries significant mass, an external guide is recommended to prevent excessive side-loading and premature seal wear. Operating speed for this bore size is 30-500 mm/s.
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 SAIJ200X550-50 FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 550 mm nominal stroke by up to 50 mm, creating a 500-550 mm travel window. It only sets the end position and does not hold the load without live air.
