About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X450-40
The AirTAC SAIJ200X450-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 410-450mm usable travel window. The extruded aluminum barrel includes sensor grooves on both sides for straightforward position feedback.
This adjustable variant allows technicians to dial in the exact retract position during commissioning without adding external stops. The rear mechanism functions strictly as a travel stop to set deceleration endpoints, not as a locking device, meaning it cannot hold the load without live air pressure. For secure load-holding, an external rod lock or related SAIL and BSAI series cylinders are required.

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 SAIJ200X450-40 Is Used
Heavy Press Tuning
Dial in the exact 410-450mm retract position during heavy press commissioning to accommodate varying material thicknesses without swapping cylinders.
Product Changeover
Quickly adjust the end-stop on automated assembly lines when switching between different product sizes, leveraging the 40mm travel window.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X450-40 the Right Cylinder?
If your force requirements are lower, stepping down to a 160mm bore yields 10053N at 0.5 MPa, which might be a more efficient choice. The SAIJ200X450-40 is chosen over a fixed SAI cylinder when machine setups demand variable end-stops for product changeovers.
When replacing an ISO 15552 cylinder, match the 200mm bore, 450mm stroke, PT tapered port threads, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because this unit lacks the -S magnet option, it will not support AirTAC CMSE or DMSE sensors without modification. Additionally, with a 450mm stroke, the long unsupported travel requires an external guide to prevent excessive side-loading on the 40mm rod.
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 SAIJ200X450-40 FAQ
At the maximum 1.0 MPa pressure, it delivers up to 3204 kgf.
The rear adjuster screw acts as a mechanical stop that trims the effective stroke back by up to 40mm, creating a 410-450mm usable travel window. It sets the end position but does not lock the load without continuous air pressure.
