About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX160-40S
The AirTAC SAIJ80X160-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel window down to 120 mm from its 160 mm nominal stroke. This on-the-fly adjustment is ideal for product changeovers, letting you dial in the exact end position without swapping the cylinder or adding bulky external stops. It delivers robust thrust, generating 2268 N of pull force at 0.5 MPa and up to 4523 N at 0.9 MPa.
This specific SKU is configured with a SUS420J2 stainless steel rod for superior corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel features sensor grooves on both sides for flexible switch mounting. It uses a G3/8 PT port and supports a speed range of 30-800 mm/s. The rear adjuster acts purely as a mechanical stop to set the travel end and 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 SAIJ80AX160-40S Is Used
Product Changeover
Quickly adjust the end stop from 160 mm down to 120 mm to accommodate different package sizes on a packaging line without changing out the cylinder.
End-Position Tuning
Fine-tune the retract stroke during machine commissioning to achieve exact positioning, preventing mechanical crashes without adding external stops.
Sensor-Integrated Control
Leverage the built-in magnet with DMSE electronic sensors to confirm the adjusted end-of-stroke positions for precise automated sequencing.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX160-40S the Right Cylinder?
Choose this 80 mm bore when your application requires substantial force, such as the 2268 N pull at 0.5 MPa provided here. If your setup needs less force, stepping down to a 63 mm bore yields 1402 N of pull force, while moving up to a 100 mm bore increases the pull force to 3681 N at the same pressure. The 40 mm adjustment range on this model is perfect for machines that handle multiple product sizes, giving you a 120-160 mm travel window to dial in during commissioning without needing a fixed-stroke SAI cylinder.
Because this is a standard 160 mm stroke, side-loading risks are manageable, but always ensure proper guiding for heavy loads. Remember that the rear adjuster is a travel stop, not a lock; if you need true fail-safe load holding without live air, consider the AirTAC SAIL or BSAI series. This model is dimensionally interchangeable per ISO 15552 and uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ80AX160-40S FAQ
The rear adjusting screw acts as a mechanical stop, allowing you to shorten the effective stroke anywhere within a 120-160 mm travel window. It sets the travel end but does not lock or hold the load without continuous air pressure.
