About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX220-75S
The AirTAC SAIJ80X220-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 145-220 mm usable travel window. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet works seamlessly with AirTAC CMSE reed and DMSE electronic switches for precise end-of-stroke detection.
This variant uses a SUS420J2 stainless steel piston rod (code A) for enhanced corrosion resistance compared to standard carbon steel. The rear adjustment screw acts as a mechanical stop to fine-tune the retract position during commissioning or product changeover without adding external stops. Remember that this adjuster only sets the travel end point; 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 SAIJ80AX220-75S Is Used
Product Size Changeovers
Dial in the exact 145 to 220 mm retract stop during machine format changes without physically swapping the cylinder or bolting on external stops.
Variable End-Position Setup
Perfect for automated assembly stations where the final end-of-stroke position must be fine-tuned at commissioning to dial out mechanical slop.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX220-75S the Right Cylinder?
Choose this 80 mm bore cylinder when an application requires a 220 mm stroke that must be dialed back by up to 75 mm to accommodate varying product sizes on a line. The PT tapered port (G3/8) ensures a tight, reliable pneumatic connection. Because the 220 mm stroke is relatively long, the 25 mm rod diameter provides excellent rigidity, but an external guide rail is still recommended to manage side loads. For load-holding without live pressure, select a SAIL or BSAI series cylinder instead of relying on the adjuster. This model is dimensionally interchangeable per ISO 15552.

- ✓ 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 SAIJ80AX220-75S FAQ
At the maximum 1.0 MPa pressure, it achieves a push force of 513 kgf.
The rear mechanical screw stopper allows you to shorten the effective travel from the 220 mm nominal stroke down to as little as 145 mm. This creates a 145-220 mm adjustable window for fine-tuning the retract end position without replacing the cylinder.
