About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX115-30
The AirTAC SAIJ80X115-30 is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. By turning the rear screw, you can trim the effective travel back by up to 30mm, creating an exact 85-115mm usable stroke window without needing external stops.
This unit is configured with a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets to streamline the adjustable rear housing design.

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 SAIJ80BX115-30 Is Used
Machine Changeover
Dial in the 85-115mm retract window during product size changes to set new end positions rapidly without mechanical retooling.
End-Stop Calibration
Fine-tune the final resting position of a tooling plate at commissioning, absorbing mechanical tolerances by trimming up to 30mm of travel.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX115-30 the Right Cylinder?
Select this 80mm bore cylinder when an application requires substantial thrust combined with on-the-fly end-position tuning. If your setup demands less force, stepping down to a 63mm bore yields 1559N at 0.5MPa; conversely, moving up to a 100mm bore provides 3927N. Choose the SAIJ adjustable-stroke format over a fixed SAI model when you need to fine-tune the retract position during commissioning or accommodate product changeovers without swapping hardware.
Because the stroke is 115mm, side-load stress is moderate, but always ensure external guiding for optimal seal longevity. The rear adjuster functions strictly as a travel stop and works alongside the standard air cushions to decelerate the load, but it does not hold position without live air pressure. For load-holding requirements without continuous air, consider an external rod lock, a pilot-operated check valve, or AirTAC SAIL and BSAI locking cylinders.

- ✓ 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 SAIJ80BX115-30 FAQ
At 0.7MPa, the push force increases to 3518N.
The rear adjusting screw acts as a mechanical stopper that lets you shorten the nominal 115mm stroke by up to 30mm, providing an adjustable travel window of 85-115mm. It sets the end position but does not lock the load without continuous air pressure.
