About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX170-40
The AirTAC SAIJ80X170-40 is a double-acting ISO 15552 profile cylinder featuring a rear mechanical stroke adjuster. It provides a usable travel window of 130 to 170 mm, allowing you to dial back the nominal 170 mm stroke by up to 40 mm during commissioning without adding external stops.
This unit uses a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and features tapered PT G3/8 ports. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. It supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets.

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 SAIJ80AX170-40 Is Used
Machine Changeover
Dial in the exact 130 to 170 mm end position during product size changes without physically swapping the cylinder or bolting on external stoppers.
End-Position Tuning
Fine-tune the retract stroke by up to 40 mm at commissioning to absorb mechanical tolerances and achieve precise positioning on the tooling.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX170-40 the Right Cylinder?
Choose this 80 mm bore over the 63 mm size (1402 N pull at 0.5 MPa) when your application demands higher thrust, or step down to the 50 mm bore (825 N pull) for lighter loads. An adjustable stroke is ideal for product changeovers where the exact end-of-travel position varies, unlike a fixed-stroke SAI cylinder. Because the rear screw is a travel stop and not a lock, this cylinder will not hold a load without live air pressure; consider SAIL or BSAI models for fail-safe load holding. For any stroke at or above 300 mm, use an external guide to prevent rod side-loading, though this 170 mm stroke is well within safe limits.
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 SAIJ80AX170-40 FAQ
At the maximum rated pressure of 1.0 MPa, it can deliver up to 513 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke from its 170 mm nominal length down to 130 mm. This creates a 40 mm adjustable travel window for fine-tuning the end position without replacing the cylinder.
