About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX550-75S
The AirTAC SAIJ80X550-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 475-550 mm usable travel window, allowing you to dial back the 550 mm nominal stroke by up to 75 mm during commissioning. This prevents the need to swap cylinders or bolt on external stops when finalizing end positions.
The extruded aluminum barrel includes sensor grooves on both sides, and the G3/8 PT ports handle the required air volume for smooth operation.

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 SAIJ80AX550-75S Is Used
Machine Setup & Changeover
Fine-tune the 475-550 mm travel window during line changeovers to accommodate different product sizes without replacing the cylinder.
Variable End-Stop Positioning
Adjust the retract end-position on the fly for sorting or diverter gates that need flexible stroke lengths based on package dimensions.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX550-75S the Right Cylinder?
Choose this 80 mm bore when your application requires substantial force, pushing 4523 N at 0.9 MPa. If you need less force, stepping down to a 63 mm bore yields 2805 N; if you need more, a 100 mm bore provides 7068 N. The 75 mm adjustable stroke is ideal for product changeovers on a line, letting you set variable end-stops on the fly.
Since the 550 mm stroke is relatively long, an external guide is recommended to manage side loads on the 25 mm rod. Remember that the rear adjuster acts as a travel stop, not a lock; the SAIJ does not hold loads without live air. For load-holding without pressure, use an external rod lock or pilot-operated check valve. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ80AX550-75S FAQ
