About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX450-40S
The AirTAC SAIJ80X450-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 410-450 mm usable travel window. The extruded aluminum barrel includes sensor grooves on both sides for straightforward switch placement.
This unit is equipped with a SUS304 stainless steel rod for corrosion resistance and a PT tapered port. The rear adjuster acts purely as a mechanical stop to set the retract end position during commissioning. It does not lock the load without live air pressure; for fail-safe holding, consider the SAIL or BSAI series.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 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 SAIJ80 Adjustable Cylinder SAIJ80BX450-40S Is Used
Position Calibration
Dial in the exact retract distance within the 410-450 mm window during machine commissioning to perfect product handling without physical shims.
Product Changeover
Quickly adapt the end-stop for different package sizes on a packaging line, using the 40 mm adjustment range to switch formats efficiently.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX450-40S the Right Cylinder?
Choose this adjustable-stroke model when your machine setup requires fine-tuning the end-of-travel position without adding external stops or swapping cylinders. At 450 mm of stroke, the 25 mm rod diameter and M20x1.5 thread provide robust support, but an external guide is recommended to manage side loads over this long travel distance. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.
If your application needs less force, stepping down to a 63 mm bore yields 1402 N of pull at 0.5 MPa. This specific SKU ships configured with a PT port, a SUS304 rod, and an -S magnet compatible with CMSE reed and DMSE electronic sensors.
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 SAIJ80 Adjustable Cylinder SAIJ80BX450-40S FAQ
At 0.9 MPa, the push force increases to 4523 N.
The rear adjuster lets you mechanically shorten the 450 mm nominal stroke down to 410 mm. It acts as a travel stop for end-position tuning and is not a load-holding lock.
