About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX260-30
The AirTAC SAIJ80X260-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster.
This unit features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads (G3/8). The extruded aluminum barrel includes dual sensor grooves, though this specific SKU omits the magnet, meaning CMSE or DMSE switches cannot be used without modification.

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 SAIJ80BX260-30 Is Used
Product Changeover
Quickly fine-tune the 230-260mm travel window during packaging line format changes to accommodate different carton sizes without changing cylinders.
End-Stop Calibration
Dial in the exact retract position during machine setup, using the rear screw to absorb minor mechanical deviations rather than remachining stop blocks.
Corrosive Assembly
Leverage the SUS304 stainless steel rod for pushing or clamping components in humid or mildly corrosive manufacturing environments.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX260-30 the Right Cylinder?
Select this 80mm bore when an application requires more thrust than a 63mm cylinder (1559N at 0.5 MPa) but less than a 100mm unit (3927N). The 30mm adjustment window is ideal for product changeovers, allowing you to shorten the effective stroke on the fly instead of installing fixed external stops. For holding loads without live air pressure, note that the rear adjuster acts only as a travel stop; you would need an external rod lock or an AirTAC SAIL cylinder.
Because the 260mm stroke exceeds 300mm? No, but at 260mm with a 25mm rod, guiding is still recommended for heavy lateral loads. To match this ISO 15552 replacement exactly, specify bore 80, stroke 260, 30mm adjust, PT G3/8 ports, SUS304 rod, and no magnet.
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 SAIJ80BX260-30 FAQ
At 0.7 MPa, the push force increases to 3518N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the nominal 260mm stroke by up to 30mm, creating a 230-260mm usable travel window. It is a stop, not a lock, and requires live air to maintain position.
