About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX220-50S
The AirTAC SAIJ80X220-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 170 to 220 mm usable travel window. A PT tapered G3/8 port supplies air, while variable cushions at both ends manage deceleration.
This adjustable-stroke design lets you fine-tune the retract end position during commissioning without adding external stops. The rear adjuster acts purely as a travel stop, not a lock, so it cannot hold a load without live air pressure. It uses a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

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 SAIJ80BX220-50S Is Used
Product Changeovers
Dial in the 170-220 mm travel window during format size changes on a packaging line without physically replacing the actuator.
End-Position Tuning
Fine-tune the retract stroke at machine commissioning to achieve exact positioning, avoiding the need for external mechanical stops.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX220-50S the Right Cylinder?
The 50 mm adjustment range is ideal for product changeovers on a line, letting you shift the end-stop dynamically rather than swapping to a fixed-stroke SAI cylinder. If your application requires the load to be held mechanically without continuous air, select a SAIL or BSAI cylinder instead of relying on this adjuster.
For an exact ISO 15552 replacement, match the 80 mm bore, 220 mm nominal stroke, 50 mm adjustment, PT G3/8 port, and the -S magnet. Because the stroke is 220 mm, ensure adequate external guiding to prevent excessive side-loading on the 25 mm rod, despite the robust M20x1.5 rod thread handling standard operational stresses.
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 SAIJ80BX220-50S FAQ
The rear adjuster acts as a stop that lets you mechanically shorten the effective stroke by up to 50 mm. This creates a usable travel window of 170 to 220 mm, allowing precise end-position tuning without changing the cylinder.
