About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX260-40S
The AirTAC SAIJ80X260-40-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting.
This specific SKU is configured with a SUS304 stainless steel rod for superior corrosion resistance and features a built-in magnet for position detection. The rear stopper acts as a travel end-set for product changeovers, but it is not a locking device. For load-holding without live air pressure, consider an external rod lock or the AirTAC SAIL series.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
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 SAIJ80BX260-40S Is Used
Variable End-Stop Tuning
Dial in the retract position within the 220-260mm window during machine commissioning to achieve perfect alignment without adding external mechanical stops.
Product Size Changeover
Quickly adapt packaging or handling lines to new part dimensions by turning the rear adjuster, reducing downtime between production runs.
Corrosion-Resistant Actuation
Leverage the SUS304 stainless steel rod in light washdown or humid environments where standard carbon steel rods might degrade over time.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX260-40S the Right Cylinder?
If your setup only needs 1559N, stepping down to a 63mm bore saves space, while moving up to a 100mm bore yields 3927N for heavier loads. The adjustable 220-260mm window is ideal for fine-tuning end positions at commissioning rather than machining custom external stops.
When replacing an ISO 15552 cylinder, match the 80mm bore, 260mm nominal stroke, 40mm adjustment range, PT tapered port threads, and the -S magnet requirement. Because the 260mm stroke is substantial, ensure adequate external guiding to prevent side-loading damage to the 25mm rod. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR.
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 SAIJ80BX260-40S FAQ
At 0.7 MPa, the push force increases to 3518N.
The rear adjuster allows you to shorten the effective stroke by up to 40mm from the 260mm nominal length, creating a usable travel window of 220 to 260mm. It functions as a mechanical stop for end-position tuning and does not lock the load without live air.
