Airtac SAUD Double Rod Cylinder SAUD80X55
The AirTAC SAUD Double Rod Cylinder SAUD80X55 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 55mm 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 SAUD80X55
The SAUD80X55 is a double-acting, double-rod profile cylinder. A rod protrudes from both ends, meaning both faces use the rod-side piston area. This yields equal output force in both directions, rated at 2268 N each way at 0.5 MPa. The 3/8 inch port feeds the 80 mm bore, which uses a 25 mm rod with an M20x1.5 thread.
Because the extruded aluminum profile barrel lacks external rods, this unit is shorter than an ISO 15552 cylinder of the same bore. The twin rods prevent rotation and provide stable guidance for twin-tool setups. This SKU lacks a magnet, so it cannot accept CMSG or DMSG sensors.

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 SAUD80X55 Is Used
Twin-Spindle Drilling
Drives two opposing drill heads simultaneously with equal 2268 N force, keeping the cycle balanced without needing separate valves.
Dual-End Transfer
Pushes a workpiece forward on the extend stroke while retracting an empty pallet backward, maximizing throughput in a short footprint.
Anti-Rotation Lift
Lifts a 116 kg vertical load using the twin rods to prevent twisting, ensuring the payload stays perfectly aligned during travel.
Is the Airtac SAUD Double Rod Cylinder SAUD80X55 the Right Cylinder?
Choose this 80 mm bore delivering 2268 N both ways when you need to drive two tools at once or prevent twist on the return stroke. If your project needs less force, the 63 mm bore provides 1402 N both ways; if you need more, the 100 mm bore offers 3681 N both ways. Mounting is limited to Basic, FA, and LB brackets that match the AirTAC SC series. Since this specific SKU has no internal magnet, you cannot mount position switches on it. For any stroke over 300 mm, add external guide rails to handle side loads and protect the seals.
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 SAUD80X55 FAQ
The force is equal in both directions because it is a double-rod design. It outputs 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa on both extend and retract.
No, a plain double-rod cylinder drifts without live air; the adjustable 28 mm cushions only decelerate near the stroke ends. Use an external rod lock or pilot-operated check valve for secure load holding.
