About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX55-50S
The AirTAC SAIJ80X55-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window down to 5-55 mm. The extruded aluminum barrel includes sensor grooves on both sides, supporting CMSE reed and DMSE electronic switches via its built-in magnet.
This adjustable-stroke variant omits the FB, CA, CB, and CR mounting options, utilizing a focused set of interfaces (Basic, FA, LB, TC, FTC, TCM1, TCM2) for streamlined machine integration. The rear stopper screw lets you dial in the exact retract position during commissioning without adding external stops. Remember that this adjuster acts purely as a travel stop, not a load-holding lock; for dead-pilot pressure holding, consider the SAIL or BSAI series.

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 SAIJ80AX55-50S Is Used
Product Changeovers
Dial in the retract position up to 50 mm during packaging line format changes without replacing the cylinder.
Machine Setup
Fine-tune the end-stop at commissioning to perfect pressing depth, avoiding the need for external mechanical stops.
Variable End Stops
Adjust the 5-55 mm travel window on the fly for multi-model assembly lines requiring flexible positioning.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX55-50S the Right Cylinder?
Choose this 80 mm bore when your application requires substantial thrust—stepping down to a 63 mm bore reduces your push force to 1559 N at 0.5 MPa. The -50 adjustment code is ideal for product changeovers where the end-of-stroke position varies by up to 50 mm, saving the cost of swapping a fixed-stroke SAI cylinder. To replace an ISO 15552 unit, match the 80 mm bore, 55 mm nominal stroke, PT G3/8 ports, and the -S magnet requirement.
Because the nominal stroke is only 55 mm, the 25 mm rod and M20x1.5 thread provide excellent rigidity without needing an external guide. Operating speeds of 30-800 mm/s are achievable, but note that the rear adjuster and air cushions only decelerate the load; they will not hold it without live air pressure.
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 SAIJ80AX55-50S FAQ
The rear adjuster screw allows you to shorten the 55 mm nominal stroke by up to 50 mm, creating a usable travel window of 5 to 55 mm. This stopper only sets the end position and does not lock the load without live air.
