About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX260-30S
Because this SKU carries a 30 mm adjustment code, you can fine-tune the effective travel anywhere within a 230 to 260 mm window during commissioning without physically swapping the unit. This specific configuration features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing.
It uses a PT tapered G3/8 port and relies on the extruded aluminum barrel design rather than a tie-rod construction. The rear stopper mechanism and the variable air cushions at both ends serve to set and decelerate the end-of-travel position; neither component will hold a load without continuous air pressure. For true load-holding requirements, 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 SAIJ80BX260-30S Is Used
Adjustable Machine Stops
Dial in the exact end-position within the 230-260 mm window during machine setup or product changeover without adding external physical spacers.
Variable Position Clamping
Securely clamp different sized workpieces on a single fixture by adjusting the cylinder's effective stroke to match each part's dimensions.
Variable Diverting Gate
Control the exact travel distance of a sorting gate on a conveyor line to accommodate packages of varying widths on the fly.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX260-30S the Right Cylinder?
The adjustable 230 to 260 mm travel window is ideal for product-size changeovers on a line, allowing operators to dial in a new end-stop quickly instead of installing fixed spacers or a standard SAI cylinder.
When matching an ISO 15552 replacement, verify the 260 mm stroke, 30 mm adjustment range, PT G3/8 port, and the -S magnet compatibility with AirTAC CMSE reed and DMSE electronic switches. Since the stroke is 260 mm, ensure proper external guiding to prevent side-loading forces on the 25 mm rod and M20x1.5 thread, as long unsupported strokes can induce wear.
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 SAIJ80BX260-30S FAQ
The rear adjuster screw allows you to shorten the nominal 260 mm stroke by up to 30 mm, creating a usable travel window between 230 and 260 mm. The adjuster acts as a mechanical stop and does not lock the load without live air pressure.
