About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX165-75S
The AirTAC SAIJ80X165-75-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a substantial 2513N pull force at 0.5 MPa, making it well-suited for heavier manipulation tasks. The integrated -S magnet enables direct mounting of CMSE reed and DMSE electronic sensors along the dual-side barrel grooves for precise position verification.
This specific SKU features a 165 mm nominal stroke that can be dialed back by up to 75 mm, creating a highly flexible 90-165 mm usable travel window. The rod is constructed from SUS420J2 stainless steel, offering enhanced corrosion resistance, and uses an M20x1.5 thread. The rear stopper mechanism allows operators to fine-tune end positions during commissioning or product changeovers without adding external stops or swapping the cylinder.

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 SAIJ80AX165-75S Is Used
Variable End-Stop Machining
Dial in the 90-165 mm travel window on the fly to accommodate different part lengths during multi-stage machining operations.
Product Changeover Diverter
Quickly reposition the diverter end-stop by up to 75 mm when switching conveyor line product sizes, avoiding mechanical teardown.
Commissioning Fine-Tuning
Use the rear adjuster to perfectly set the retraction end-position during initial machine commissioning without adding external stopper blocks.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX165-75S the Right Cylinder?
Choose this 80 mm bore when your application requires the 2513N pull force at 0.5 MPa, stepping up from a 63 mm bore that provides 1402N pull, or stepping down from a 100 mm bore offering 3681N pull. The extensive 75 mm adjustment range is ideal for machinery processing varying product sizes, allowing rapid end-stop modifications without replacing the cylinder. Fluid connections use a PT tapered G3/8 port.
For any setup utilizing a 165 mm stroke, ensure adequate external guiding to prevent excessive side-loading on the M20x1.5 piston rod. Remember that the rear adjuster acts purely as a travel stop to set deceleration and end-position, not as a locking device; the SAIJ80X165-75-S will not hold a load without live air pressure. For fail-safe load holding, consider the SAIL or BSAI series. Mounting options include 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 SAIJ80AX165-75S FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 513 kgf.
The rear adjuster screw allows you to shorten the 165 mm nominal stroke by up to 75 mm, providing an adjustable travel window of 90 to 165 mm. This stopper sets the end position but does not lock the load without live air pressure.
