Airtac SAUD Double Rod Cylinder SAUD80X220
The AirTAC SAUD Double Rod Cylinder SAUD80X220 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 220mm stroke, 3/8" air ports and adjustable end cushioning. Its hard-anodized aluminum-profile barrel is shorter than an ISO 15552 cylinder of the same bore, and it shares SC-series mounting accessories.

About the Airtac SAUD Double Rod Cylinder SAUD80X220
The AirTAC SAUD80X220 is a double-acting, double-rod profile cylinder. An extruded aluminium barrel keeps the unit shorter than an ISO 15552 cylinder of the same 80mm bore. Because a rod exits both ends, the push and pull force is equal at 2268 N each way at 0.5 MPa.
This 220mm stroke model uses a 3/8 inch port and a 25mm piston rod with an M20x1.5 thread. The twin-rod geometry prevents rotation and lets you mount twin tooling.

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 SAUD Double Rod Cylinder SAUD80X220 Is Used
Twin-Spindle Drilling
Drives two synchronized machining heads from one piston, ensuring parallel hole patterns without torsional deflection.
Dual Transfer Pushers
Pushes alternating carton lanes in opposite directions using both rod ends, saving space in compact packaging cells.
Balanced Lift Stations
Lifts platens evenly because the equal force both ways prevents sagging on the return stroke during vertical actuation.
Is the Airtac SAUD Double Rod Cylinder SAUD80X220 the Right Cylinder?
Select this 80mm bore (2268 N both ways at 0.5 MPa) if your task demands anti-rotation guidance or twin tools. Step down to the 63mm bore for 1402 N, or up to the 100mm bore for 3681 N. Mounting uses SC-series FA or LB brackets. Since this is a no-magnet SKU, it cannot take CMSG or DMSG sensors. At 220mm stroke, side loads are low, but always use external guides for heavier offsets. Note that air cushions only decelerate; use an external rod lock to hold loads.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/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 — same as SC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAUD Double Rod Cylinder SAUD80X220 FAQ
The force is equal in both directions because it is a double-rod cylinder. It outputs 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa. The 3/8 inch port feeds both chambers equally.
No, this specific SKU lacks a magnet so it cannot take CMSG, DMSG, or EMSG switches. You would need the -S variant for internal sensing, though you can still mount an external switch cam on the back rod.
