About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX115-75S
The AirTAC SAIJ80X115-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the nominal 115 mm travel back by up to 75 mm. This creates a wide usable stroke window of 40 to 115 mm, letting you dial in the exact end position during commissioning without swapping hardware.
This specific SKU is built with a SUS304 stainless steel rod for superior corrosion resistance and includes a magnetic piston for position sensing. The sensor groove on both sides of the extruded aluminum barrel accepts AirTAC CMSE reed and DMSE solid-state switches. The rear adjuster acts purely as a mechanical stop to set the retract 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 SAIJ80BX115-75S Is Used
Variable End-Stop Positioning
Dial in the retract distance from 40 to 115 mm during machine setup to accommodate changing material thicknesses without adding external stopper blocks.
Product Size Changeover
Quickly reconfigure the effective stroke on automated lines when switching between different product sizes, minimizing downtime and avoiding cylinder swaps.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX115-75S the Right Cylinder?
If you need less force, stepping down to a 63 mm bore yields 1559 N, while stepping up to a 100 mm bore provides 3927 N. The adjustable stroke is ideal for product changeovers on a line, replacing fixed-stroke SAI cylinders when exact travel distances fluctuate.
To match this ISO 15552 interchangeable cylinder, confirm the 115 mm nominal stroke, 75 mm adjustment range, PT tapered port threads, and the -S magnet option. For operations requiring the load to be physically held in place without continuous air pressure, this cylinder is insufficient; you must select a SAIL pneumatic lock, a BSAI clamp-lock, or an external rod lock instead.

- ✓ 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 SAIJ80BX115-75S FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 513 kgf of push force.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 115 mm nominal stroke by up to 75 mm, providing a usable travel window of 40 to 115 mm. It only sets the end position and does not lock or hold the load without live air pressure.
