Airtac SAUD Double Rod Cylinder SAUD80X20S
The AirTAC SAUD Double Rod Cylinder SAUD80X20S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 20mm 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 SAUD80X20S
The AirTAC SAUD80X20S is a double-acting, double-rod profile cylinder. A 25mm rod exits both ends of the hard-anodized extruded aluminum barrel, meaning both faces use the rod-side piston area. This yields exactly 2268 N of thrust and pull at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa. The 3/8 inch port feeds the chambers, and the unit runs at 30-800 mm/s.
This compact profile body is shorter than a standard ISO 15552 cylinder of the same 80mm bore. The built-in magnet (-S) supports CMSG, DMSG, or EMSG switches for position tracking.

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 SAUD80X20S Is Used
Twin-Tool Stamping
Drives two synchronized forming punches from one piston, ensuring parallel contact on sheet metal workpieces without rotational twist.
Dual Transfer Pusher
Pushes cartons from a main line onto a spur belt using the front rod, while the back rod trips a mechanical diverter flag.
Gripper Cam Actuation
Uses the rear protruding rod as a cam surface to mechanically open a heavy-duty pallet gripper assembly during approach.
Is the Airtac SAUD Double Rod Cylinder SAUD80X20S the Right Cylinder?
Choose this 80mm bore when you need 2268 N of equal push and pull force. If your project requires less power, step down to the 63mm bore which provides 1402 N both ways. If you need more, the 100mm bore offers 3681 N each direction. The double-rod architecture is ideal for anti-rotation guidance, driving twin tooling, or mounting a sensor cam on the back rod. You can mount it using basic, FA flange, or LB foot brackets that match the AirTAC SC series. The -S magnet allows solid state or reed sensing. Because the 20mm stroke is short, side-load stress is minimal, but always guide external loads to prevent binding.
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 SAUD80X20S FAQ
The force is equal in both directions because of the double-rod design. It generates 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa. The cylinder uses a 3/8 inch port and has a 25mm diameter rod exiting both ends.
No, the adjustable 28mm air cushion only decelerates the piston near the stroke ends and does not lock the load. If power fails, the piston will drift. For vertical load holding, you must install an external rod lock or a pilot-operated check valve.
