About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX300-10
The AirTAC SAIJ80X300-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. With a nominal 300mm stroke, the external stopper lets you dial back the effective travel by up to 10mm, creating a 290-300mm usable window for precise end-position tuning.
This model features tapered PT ports and dual-side sensor grooves on the extruded aluminum barrel. The rear adjuster acts solely as a travel stop to set deceleration endpoints and cannot hold a load without live air pressure. For position holding without pressure, an external rod lock or related SAIL series is required.

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 SAIJ80BX300-10 Is Used
Machine Changeover
Dial in the exact 290-300mm retract stop during product size transitions without replacing the cylinder or bolting on external stops.
End-Position Tuning
Fine-tune the retract endpoint at commissioning to absorb mechanical tolerance and ensure precise placement of heavy fixtures.
Variable End Stops
Adjust the travel end on a conveyor divert or reject mechanism to accommodate different package dimensions on the fly.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX300-10 the Right Cylinder?
The 10mm adjustment range is ideal for fine-tuning retract positions during machine setup or product changeover without adding external stops or swapping a fixed-stroke SAI cylinder. Because the 300mm stroke is relatively long, the 25mm rod and M20x1.5 thread can handle side loads, but an external guide is recommended for unsupported loads. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ80BX300-10 FAQ
At 0.7 MPa the push force increases to 3518N.
The rear adjuster screw lets you shorten the 300mm nominal stroke by up to 10mm, providing a 290-300mm usable travel window. It acts as a travel stop and does not lock the load without air pressure.
