About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX170-40S
The AirTAC SAIJ80X170-40-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. The built-in PT G3/8 porting and variable air cushions at both ends ensure robust and stable pneumatic performance.
With a 40mm adjustment range, this specific SKU provides a usable travel window of 130-170mm. This allows you to fine-tune the retract end position during commissioning without swapping the cylinder or adding external stops. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet works directly with AirTAC CMSE reed and DMSE electronic solid-state switches.

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 SAIJ80AX170-40S Is Used
Product Changeovers
Quickly dial the retract stroke back by up to 40mm when switching between product sizes on a packaging line, avoiding the need to physically swap out cylinders.
End-Stop Calibration
Fine-tune the final end position during machine commissioning to achieve precise mechanical alignment without relying solely on external shims or stops.
Variable Forming Stops
Set distinct travel limits for multi-stage operations, using the 130-170mm window to safely control the stroke length for different forming depths.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX170-40S the Right Cylinder?
The adjustable 130-170mm travel window is ideal for product-size changeovers on a line, letting you dial in the exact end-stop mechanically. For mounting, SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets, deliberately omitting FB, CA, CB, and CR options.
When ordering an exact ISO 15552 replacement, match the 80mm bore, 170mm nominal stroke, 40mm adjuster, PT G3/8 port, and the -S magnet. Since the 170mm stroke is under 300mm, side-load stress is moderate, but the 25mm rod and M20x1.5 thread still provide excellent rigidity. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, consider an external rod lock or the AirTAC SAIL/BSAI series.
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 SAIJ80AX170-40S FAQ
At 0.7MPa, the push force increases to 3518N.
The rear adjuster screw acts as a mechanical stop that shortens the retract stroke. For this 170mm nominal stroke cylinder, the -40 code means you can trim the effective travel back by up to 40mm, creating a 130-170mm usable window. It functions as a stop, not a lock.
