About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX290-10S
The AirTAC SAIJ80X290-10-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. The integrated -S magnet enables position sensing with AirTAC CMSE reed or DMSE electronic solid-state switches housed in the dual-side sensor grooves.
This specific SKU features a 10mm adjustment range, creating a precise 280-290mm usable travel window for fine-tuning the retract end position during commissioning. It is built with a SUS304 stainless steel rod (code B) for superior corrosion resistance and utilizes PT tapered port threads (G3/8). The extruded aluminum barrel maintains standard ISO 15552 mounting dimensions without relying on tie-rods.

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 SAIJ80BX290-10S Is Used
Machine Changeover
Dial in the 280-290mm retract position precisely during product size changes without physically replacing the actuator or adding shims.
End-Stop Calibration
Fine-tune the final resting position of tooling at commissioning, absorbing mechanical tolerances via the rear 10mm stopper screw.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX290-10S the Right Cylinder?
The adjustable stroke is ideal for variable end-stops or product changeovers, allowing you to dial in the exact 280-290mm position without swapping the cylinder or adding external stops. Note that the rear adjuster functions strictly as a travel stop and does not lock the load; for true load-holding without live air pressure, consider an AirTAC SAIL or BSAI cylinder.
Because this model has a 290mm stroke, the 25mm diameter piston rod and M20x1.5 rod thread provide excellent rigidity, but an external guide is still recommended to prevent excessive side-loading on long unsupported travels. As an ISO 15552 interchangeable cylinder, ensure your replacement matches the 80mm bore, 290mm stroke, 10mm adjustment, PT port thread, and -S magnet configuration. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR.

- ✓ 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 SAIJ80BX290-10S FAQ
At 0.5 MPa, the push force is 2513N.
The rear adjuster acts as a mechanical stop that allows you to shorten the effective travel from the nominal 290mm down to 280mm. It only sets the end position and does not lock the load without live air.
