About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX125-10
The AirTAC SAIJ80X125-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
This SKU is configured with a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads with a G3/8 connection. The rear stopper screw acts purely as a travel end-deceleration device, meaning it does not lock or hold the load without continuous live air pressure.

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 SAIJ80BX125-10 Is Used
End-Position Tuning
Dial in the exact retract distance within a 115-125mm window during machine setup to perfect part ejection without changing the cylinder.
Product Changeover
Quickly adjust the stroke by up to 10mm on a packaging line when switching to a slightly different product size.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX125-10 the Right Cylinder?
The 10mm adjustment range is ideal for fine-tuning end positions during machine commissioning or minor product changeovers, avoiding the need to bolt on external stops. For true load-holding without air pressure, consider an AirTAC SAIL or BSAI cylinder instead.
When matching ISO 15552 replacements, verify the 125mm stroke, 10mm adjustment range, G3/8 PT ports, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the stroke is under 300mm, side-load risks are minimal, but the robust 25mm rod still handles standard operational stresses effectively.
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 SAIJ80BX125-10 FAQ
At 0.7MPa, the push force increases to 3518N.
The rear adjuster screw allows you to shorten the 125mm nominal stroke by up to 10mm, creating a 115-125mm travel window. It functions as a mechanical stop for end-position tuning and does not lock the load without live air.
