About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X450-100
The AirTAC SAIJ200X450-100 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications. It features a rear stroke adjuster that allows you to dial back the 450 mm nominal stroke by up to 100 mm, creating a precise 350-450 mm usable travel window for product changeovers. The extruded aluminum barrel includes sensor grooves on both sides for straightforward position feedback.
This model uses a robust 40 mm carbon steel rod with an M36x2 thread, providing high rigidity against side loads. Air is supplied through a G3/4 PT tapered port, and variable air cushions at both ends absorb the significant kinetic energy of this large bore. The rear adjuster acts purely as a mechanical stop to set the end position and does not hold the load 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 SAIJ200X450-100 Is Used
Heavy Press Tuning
Dial in the exact 350-450 mm end position for large metal forming or stamping presses during setup.
Material Handling
Adjust the retract stop on the fly to accommodate different pallet sizes without changing the cylinder.
Assembly Line Changeover
Fine-tune the rear mechanical stop to set new end positions for varying product lengths on a shared line.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X450-100 the Right Cylinder?
Selecting this 200 mm bore cylinder is ideal when your process requires extreme force, as stepping down to a 160 mm bore drops the 0.5 MPa push force to 10053 N. An adjustable-stroke model is chosen over a fixed SAI cylinder when you need to fine-tune the end-of-travel position at commissioning or adapt to varying product sizes without adding external stops. For load-holding without continuous air pressure, this standard SAIJ is insufficient; consider the SAIL or BSAI series instead.
Because the 450 mm stroke creates a long lever arm, an external guide is strongly recommended to prevent excessive side loading on the 40 mm rod. To replace this cylinder with an equivalent ISO 15552 unit, match the 200 mm bore, 450 mm stroke, 100 mm adjustment range, G3/4 PT port, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). No magnet is specified, so CMSE or DMSE sensors cannot be used without modification.

- ✓ 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 SAIJ200X450-100 FAQ
At the maximum operating pressure of 1.0 MPa, the push force reaches 31416 N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 450 mm nominal stroke by up to 100 mm. This creates a usable travel window of 350-450 mm without needing to swap the cylinder.
