About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX195-30S
By turning the external stopper screw, you can shorten the effective travel, creating a 165-195mm usable stroke window. This allows precise end-position tuning at commissioning without bolting on external stops or swapping the cylinder.
Built with an SUS420J2 stainless steel rod and a PT tapered port, this unit includes a magnet for position sensing. It integrates seamlessly with AirTAC CMSE reed and DMSE solid-state switches via the dual-side sensor grooves on the extruded aluminum barrel. The rear adjuster acts purely as a travel stop, meaning it does not lock or hold the load without live air pressure.

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 SAIJ80AX195-30S Is Used
Changeover Tuning
Dial in the exact 165-195mm end-stop during product size changes on a conveyor line without swapping out the physical cylinder assembly.
End-Position Trimming
Fine-tune the retract stroke during machine commissioning to absorb mechanical tolerances and achieve precise positioning of 80mm bore actuators.
Sensor-Ready Setup
Leverage the integrated magnet and dual sensor grooves to mount CMSE or DMSE switches exactly where needed within the adjusted travel window.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX195-30S the Right Cylinder?
The 30mm adjustment range is ideal for product changeovers on a line, letting you dial in the exact end-stop without mechanical modifications.
If your machine requires the load to stay held without continuous air pressure, this adjustable stopper will not act as a brake—consider the SAIL or BSAI locking cylinders instead. For mounting, SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets. Since the 195mm stroke is under 300mm, side-load stress is manageable, but an external guide is still recommended for heavy lateral loads.
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 SAIJ80AX195-30S FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to trim the nominal 195mm stroke back by up to 30mm. This provides a usable travel window of 165-195mm. It only sets the end position and does not lock the load without live air pressure.
