About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX650-10
The AirTAC SAIJ80X650-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel end-point. With a nominal 650 mm stroke and a 10 mm adjustment range, it provides a usable travel window of 640 to 650 mm.
Equipped with a SUS304 stainless steel rod (option B) and PT tapered port threads, this model is built for demanding environments. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of position switches. Because the rear adjuster acts only as a mechanical stop to set deceleration and end-position, it will not hold a load without live air pressure; for dead-stop load 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 SAIJ80BX650-10 Is Used
Machine Setup Changeovers
Dial in the 640-650 mm travel window during product size changeovers to set new end-stops rapidly without replacing the cylinder or adding external mechanical stops.
End-Position Tuning
Fine-tune the retract end-position at commissioning using the rear adjuster screw, absorbing minor mechanical variances without altering the fixed 650 mm nominal stroke.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX650-10 the Right Cylinder?
Choose this 80 mm bore adjustable-stroke cylinder when your machine setup requires exact end-position tuning at commissioning or during product changeover without swapping out the entire actuator.
The SAIJ80X650-10 is dimensionally interchangeable per ISO 15552 mounting-interface dimensions. It supports a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Because the 650 mm stroke is relatively long, an external guide rail is recommended to prevent excessive side-load wear on the 25 mm rod and M20x1.5 rod thread. Operating speed ranges from 30 to 800 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 SAIJ80 Adjustable Cylinder SAIJ80BX650-10 FAQ
At 0.9 MPa, the push force increases to 4523 N, with a maximum rated force of 513 kgf at 1.0 MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from the nominal 650 mm down to 640 mm. It sets the end-position and deceleration point but does not lock the load without continuous air pressure.
