About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX165-100
The AirTAC SAIJ80X165-100 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster.
This unit uses a SUS420J2 stainless steel rod for enhanced corrosion resistance and features PT tapered port threads (G3/8). The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic switches, while the rear stopper allows fine end-position tuning without adding external stops.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
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 SAIJ80AX165-100 Is Used
Product Size Changeover
Dial in the exact end position for varying package lengths on a packaging line without physically swapping the cylinder or adding spacer blocks.
Machine Setup Commissioning
Use the 100mm adjustment range to fine-tune the retract stroke during initial assembly, compensating for mechanical tolerances directly at the rear stopper.
Variable End-Stop Forming
Adjust the effective travel window between 65mm and 165mm to accommodate multiple material bending or forming depths on a single fixture.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX165-100 the Right Cylinder?
Select this 80mm bore model when your application requires substantial thrust (up to 4523N at 0.9MPa) but demands frequent product-size changeovers, utilizing the wide 65-165mm adjustment window to adapt end positions rapidly. If your force needs are lower, stepping down to a 63mm bore yields 1559N at 0.5MPa; for heavier loads, a 100mm bore provides 3927N at 0.5MPa.
Because the 165mm stroke exceeds the 300mm threshold requiring an external guide, you should still verify side-load conditions if the load is heavily offset. The rear adjuster acts purely as a travel stop and cannot hold a load without live air pressure; for true fail-safe load holding, consider the AirTAC SAIL or BSAI cylinder series. This SAIJ model supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting interfaces.
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 SAIJ80AX165-100 FAQ
At a maximum operating pressure of 1.0MPa, it delivers up to 513kgf of push force.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from the nominal 165mm down to 65mm. It only sets the end position and does not lock the load without continuous air pressure.
