About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX55-30S
The AirTAC SAIJ80X55-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window from 25 to 55 mm. The barrel is extruded aluminum with sensor grooves on both sides for flexible switch placement.
This specific SKU includes a SUS304 stainless steel rod for superior corrosion resistance and a PT tapered port thread. It is equipped with a magnet for non-contact position sensing, compatible with AirTAC CMSE reed and DMSE electronic switches. The rear adjuster acts purely as a mechanical stop to dial in the end position during commissioning; 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 SAIJ80BX55-30S Is Used
End-Position Calibration
Dial in the exact retract distance within the 25-55 mm window during machine commissioning without needing external stopper blocks.
Product Changeover
Quickly adjust the stroke stop on automated lines when switching between product sizes, saving setup time.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX55-30S the Right Cylinder?
Select this 80 mm bore cylinder when your application requires a nominal 55 mm stroke but demands precise end-position tuning during machine setup or product changeover. Instead of swapping out a fixed-stroke SAI cylinder, the SAIJ80X55-30-S lets you dial back the travel by up to 30 mm on the fly.
Because the stroke is short, side-loading risks are minimal, but always ensure the M20x1.5 rod thread is properly aligned with your load coupling. For applications that must hold a load mechanically without continuous air pressure, this cylinder is not a lock; consider the AirTAC SAIL or BSAI series instead. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ80BX55-30S FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke from its nominal 55 mm down to 25 mm. This provides a 30 mm tuning window for precise end-position calibration during commissioning.
At the maximum operating pressure of 1.0 MPa, the push force reaches 513 kgf.
