About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX15-10
The AirTAC SAIJ80X15-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, designed for applications requiring exact short-stroke end-position tuning. The extruded aluminum barrel includes sensor grooves on both sides, allowing for flexible switch placement.
With a nominal 15mm stroke and a 10mm adjustment range, this specific SKU provides a usable travel window of 5-15mm, enabling you to fine-tune the retract position at commissioning without swapping the cylinder or adding external stops. This configuration features a SUS304 stainless steel rod for superior corrosion resistance and a PT tapered port thread. The rear adjuster acts purely as a travel stop to set the end position; it does not hold the load without live air pressure.

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 SAIJ80BX15-10 Is Used
Micro-Press Positioning
Dial in the exact 5-15mm travel window during machine commissioning to ensure a heavy-duty pressing operation bottoms out perfectly without damaging the workpiece.
Short-Stroke Clamping
Fine-tune the retract stop on the fly to accommodate minor variations in part thickness during heavy-duty clamping tasks on an automated line.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX15-10 the Right Cylinder?
Choose this 80mm bore cylinder when you need substantial force in a very compact footprint and require micro-adjustments to the end-stop. The adjustable stroke is ideal for machine setups requiring precise positioning that a fixed-stroke SAI cylinder cannot accommodate. Because the stroke is only 15mm, side-load stress on the 25mm rod is minimal, though external guides are always recommended for lateral loads. For load-holding without continuous air pressure, this cylinder is insufficient; you should integrate an external rod lock or pilot-operated check valve, or select a SAIL or BSAI variant.
To match this ISO 15552 interchangeable cylinder exactly, specify: 80mm bore, 15mm nominal stroke, 10mm adjustment range, PT port thread, SUS304 (code B) rod material, and no magnet (-S not specified). The compatible mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.

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 SAIJ80BX15-10 FAQ
At 0.7MPa, the push force increases to 3518N.
The rear adjuster screw allows you to trim the effective stroke back by up to 10mm, creating a usable travel window of 5-15mm. This stopper sets the end position but does not lock the load without live air pressure.
