About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX165-30S
The AirTAC SAIJ80X165-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the effective travel to a precise 135-165 mm window during commissioning. The barrel is extruded aluminum, not a tie-rod design, ensuring dimensionally interchangeable ISO 15552 mounting.
This specific SKU features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The rear adjuster acts purely as a mechanical stop to dial in the end position without adding external blocks; it does not lock or hold the load without live air pressure. Integrated sensor grooves on both sides accept CMSE reed and DMSE electronic switches for position feedback.

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 SAIJ80BX165-30S Is Used
Machine Changeover
Dial in the 135-165 mm travel window during product size transitions without physically swapping the actuator or adding external stopper blocks.
End-Position Tuning
Use the rear adjuster to fine-tune the retract stroke precisely during commissioning, absorbing mechanical tolerances in the fixture.
Variable End Stops
Set distinct retract positions on a conveyor sorting line to handle different package dimensions on the fly.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX165-30S the Right Cylinder?
The 30 mm adjustment range is ideal for product changeovers on a line, letting operators set a new variable end-stop without swapping the cylinder. Mounting options include the reduced SAIJ set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. For load-holding without continuous air pressure, select the SAIL or BSAI series instead, as the adjuster here is not a brake. The -S magnet pairs with AirTAC CMSE and DMSE sensors.
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 SAIJ80BX165-30S FAQ
The rear adjuster screw lets you shorten the nominal 165 mm stroke by up to 30 mm, creating a usable travel window of 135 to 165 mm. It functions as a travel stop and does not hold the load without live air.
