About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX230-40S
The AirTAC SAIJ80X230-40-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 190 to 230 mm.
This adjustable-stroke model allows you to fine-tune the retract end position at commissioning without swapping the cylinder or adding external stops. The rear adjuster acts purely as a travel stop and does not hold the load without live air, while the extruded aluminum barrel incorporates sensor grooves on both sides for flexible switch mounting.

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 SAIJ80BX230-40S Is Used
Machine Changeovers
Dial in the 190-230 mm travel window during product size changes without physically swapping out the actuator.
End-Position Tuning
Fine-tune the retract stop during commissioning to perfect seating or clamping force against varying workpieces.
Variable Diverting
Adjust the stroke on a sorting diverter to accommodate different package sizes on the fly.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX230-40S the Right Cylinder?
The adjustable 190-230 mm window is perfect for product changeovers or variable end-stops, whereas a fixed SAI cylinder locks you into a single dimension. For load-holding without live pressure, a plain SAIJ will not suffice; you should look at the SAIL or BSAI locking cylinders instead.
Because this is a 230 mm stroke, the 25 mm rod and M20x1.5 thread provide robust support, but an external guide is still recommended to prevent excessive side-loading on long travels. To match this ISO 15552 dimensionally interchangeable cylinder, specify the 80 mm bore, 230 mm stroke, 40 mm adjustment, PT port threads, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting, and the -S magnet option.
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 SAIJ80BX230-40S FAQ
At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster allows you to shorten the effective stroke by up to 40 mm, creating a usable travel window of 190 to 230 mm. It functions as a mechanical stop and does not lock the load without continuous air pressure.
