About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX125-10S
The AirTAC SAIJ80X125-10-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. The integrated -10 adjustment mechanism allows you to dial back the 125mm nominal stroke by up to 10mm, creating a precise 115-125mm usable travel window for fine-tuning at commissioning.
This variant includes a magnet for CMSE and DMSE sensors and uses a SUS304 stainless steel rod for superior corrosion resistance. Fluid ports are PT tapered G3/8. The rear adjuster acts strictly as a mechanical stop to set the travel end and decelerate the load; it is not a lock. For applications requiring position holding without live air pressure, consider the SAIL or BSAI series.

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 SAIJ80BX125-10S Is Used
Machine Setup Calibration
Dial in the exact 115-125mm end-position during commissioning to perfect pressing or clamping depth without external stopper hardware.
Product Size Changeover
Quickly adjust the retract end-stop by up to 10mm on automated lines when switching between slightly different product dimensions.
Variable End-Stop Forming
Achieve precise positioning for light forming tasks, leveraging the 2513N pull force at 0.5 MPa to securely retract the tooling.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX125-10S the Right Cylinder?
Selecting this 80mm bore adjustable-stroke cylinder over a fixed SAI model makes sense when machine setups require variable end-stops or product changeovers demand exact position tuning without physically swapping cylinders or adding external stops. If your application requires less force, stepping down to a 63mm bore yields 2182N at 0.7 MPa. Conversely, if you need higher thrust, a 100mm bore provides 5497N at 0.7 MPa.
This SAIJ80X125-10-S configuration includes a SUS304 stainless steel rod, PT tapered G3/8 ports, and a -S magnet for CMSE reed and DMSE electronic sensors. It supports the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Because the 25mm rod and M20x1.5 thread handle high side loads well, it is highly durable, though long unsupported strokes still require an external guide.

- ✓ 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 SAIJ80BX125-10S FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 10mm from the 125mm nominal length, providing a 115-125mm travel window. It functions as a mechanical stop to fine-tune the end position and does not lock the load without live air.
