About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX260-75
The AirTAC SAIJ80X260-75 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. By turning the external rear screw, you can trim the effective travel anywhere within a 185 to 260mm window, allowing precise end-position calibration without swapping hardware.
This unit features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. It relies on variable air cushions at both ends to decelerate the load smoothly across its 30-800mm/s operating speed range.

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 SAIJ80BX260-75 Is Used
Product Changeovers
Dial in the 185-260mm travel window during format size changes on a packaging line, using the rear screw to set new end positions rapidly without changing the cylinder.
Machine Setup
Fine-tune the retract end-position at commissioning to perfectly seat heavy 80mm bore tooling, avoiding the need to bolt on external physical stops.
Variable End Stops
Handle diverse part sizes on a single conveyor station by adjusting the stroke up to 75mm, relying on the SUS304 rod for durability in industrial environments.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX260-75 the Right Cylinder?
If you need less force, stepping down to a 63mm bore yields 1559N; stepping up to 100mm provides 3927N. The 75mm adjustment range is ideal for product changeovers, whereas a fixed-stroke SAI cylinder is better suited for rigid, unvarying travel limits.
Because the nominal stroke is 260mm, ensure adequate external guiding to prevent excessive side-loading on the rod. Remember that the rear adjuster acts purely as a mechanical stop and does not hold the load without live air; for true position holding, consider an AirTAC SAIL or BSAI locking cylinder. This SAIJ model is dimensionally interchangeable per ISO 15552 and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
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 SAIJ80BX260-75 FAQ
At 0.7MPa, the push force increases to 3518N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 260mm nominal stroke by up to 75mm, creating a usable travel window of 185 to 260mm. It is a travel stop, not a lock, so it cannot hold the load without continuous air pressure.
