About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX110-40S
The AirTAC SAIJ80X110-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 110 mm nominal travel by up to 40 mm. This yields a usable 70 to 110 mm end-position window for fine-tuning machinery at commissioning without swapping the unit or adding external stops.
This specific configuration features a SUS304 stainless steel rod (option B) for superior corrosion resistance in harsh or washdown environments. It includes a magnetic piston for position detection via CMSE reed or DMSE electronic sensors, and uses tapered PT port threads (G3/8). The extruded aluminum barrel design integrates sensor grooves on three sides, and the rear adjuster acts purely as a travel stop that decelerates the load—it does not hold the load without live air.

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 SAIJ80BX110-40S Is Used
Product Changeover
Rapidly modify the effective stroke from 70 to 110 mm during format changes on a packaging line, eliminating the need to physically swap cylinders for different carton sizes.
End-Stop Calibration
Fine-tune the retract end position during machine commissioning to perfect a pressing or clamping operation, dialing in exact contact without mechanical shims.
Washdown Handling
Leverage the SUS304 stainless steel rod to push heavy actuators reliably in food processing or chemical environments where standard carbon steel rods would corrode.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX110-40S the Right Cylinder?
The 40 mm adjustment range is ideal for production lines running mixed product sizes, letting operators shift the end-stop position rapidly during changeover. For load-holding without continuous air pressure, this cylinder is insufficient; the rear stop only sets the travel end, so you must specify a SAIL pilot-locking cylinder or an external rod lock.
To match this ISO 15552 replacement exactly, confirm the 80 mm bore, 110 mm nominal stroke, 40 mm adjustment code, PT G3/8 port threads, SUS304 (B) rod material, and the -S magnet option. Because the 110 mm stroke is relatively short, side-load stress on the M20x1.5 rod thread is minimal, though external guidance is always recommended for heavy lateral loads. The available mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ80BX110-40S FAQ
A rear external stopper screw lets you mechanically shorten the stroke by up to 40 mm from the 110 mm nominal length. This creates an adjustable 70 to 110 mm travel window, allowing precise end-position tuning without disassembling the cylinder.
