About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX200-20S
The AirTAC SAIJ80X200-20-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 180 to 200 mm. This specific configuration includes a magnetic piston for position sensing and PT tapered port threads.
The integrated rear adjusting screw allows precise end-position tuning during commissioning without adding external stops or swapping the cylinder. It is important to note that this rear adjuster functions strictly as a travel stop to set deceleration alongside the air cushions, not as a load-holding lock; the cylinder cannot maintain its position without live air pressure. For load-holding requirements without continuous air, an external rod lock or related AirTAC series like SAIL or BSAI should be utilized.

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 SAIJ80AX200-20S Is Used
Machine Changeover
Dial in the exact 180-200 mm end-stop during product size transitions on a packaging line without physically swapping cylinders or adding external stopper blocks.
End-Position Tuning
Fine-tune the retract stroke at commissioning to perfect the seating of a 2513 N press operation, absorbing mechanical tolerance variations directly at the rear screw.
Variable Assembly Stops
Adjust the travel window on the fly for automated assembly stations that need to accommodate slightly different part heights without reprogramming the motion controller.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX200-20S the Right Cylinder?
The adjustable stroke is ideal for machine setups requiring variable end-stops during product changeovers. Because this is a 200 mm stroke, it remains well within the 1500 mm maximum standard stroke for this bore, keeping the nonstandard flag false.
When integrating this cylinder, ensure the mounting setup matches the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, or TCM2, as FB, CA, CB, and CR mounts are omitted from this adjustable series. The magnetic piston (-S) is fully compatible with AirTAC CMSE reed and DMSE solid-state sensors fitted into the dual-side sensor grooves on the extruded aluminum barrel.

- ✓ 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 SAIJ80AX200-20S FAQ
At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster screw allows you to trim the effective stroke by up to 20 mm, creating a usable travel window of 180 to 200 mm. This mechanism acts as a physical stop for end-position tuning and does not lock or hold the load without continuous air pressure.
