About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX190-10
The AirTAC SAIJ80X190-10 is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. The integrated rear stopper allows you to trim the nominal 190mm stroke back by up to 10mm, creating a precise 180-190mm usable travel window for fine-tuning end positions during commissioning.
This variant features a SUS304 stainless steel rod (code B) for superior corrosion resistance and uses PT tapered port threads with a G3/8 connection. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to mount CMSE reed or DMSE electronic sensors if needed. The rear adjuster functions strictly as a travel stop to set deceleration, not as a lock to hold loads 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 SAIJ80BX190-10 Is Used
Machine Changeover
Quickly dial in the 180-190mm travel window using the rear screw when switching product sizes on a packaging line, avoiding physical cylinder swaps.
End-Stop Tuning
Fine-tune the final retract position during initial commissioning to achieve exact mechanical alignment without machining custom external spacers.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX190-10 the Right Cylinder?
Choose the SAIJ adjustable-stroke design over a fixed SAI model when you need to dial in a precise end-of-stroke position during machine setup or product changeover without adding external stops. To replace an ISO 15552 cylinder, match the 80mm bore, 190mm stroke, 10mm adjustment, PT G3/8 port, and mounting style.
Because this unit features a 190mm stroke, the 25mm rod and M20x1.5 thread provide robust stability, though any lengthy or heavy unsupported load should still use an external guide to prevent side-loading damage. For applications requiring true load-holding without continuous air pressure, a plain SAIJ is insufficient; consider an AirTAC SAIL or BSAI locking cylinder instead.
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 SAIJ80BX190-10 FAQ
At 0.7 MPa, the push force increases to 3518N.
The rear adjuster acts as an external stopper that lets you shorten the effective travel from the nominal 190mm down to 180mm. It sets the end position but does not lock the load without live air pressure.
