Airtac SAUD Double Rod Cylinder SAUD80X50
The AirTAC SAUD Double Rod Cylinder SAUD80X50 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 50mm 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 SAUD80X50
The AirTAC SAUD80X50 is a double-acting, double-rod profile cylinder. A 25mm rod exits both ends of the hard-anodized aluminum barrel, meaning both faces use the rod-side piston area. This yields exactly 2268 N of thrust and pull at 0.5 MPa, ensuring perfectly balanced motion. The unit is notably shorter than a standard ISO 15552 unit of the same bore.
With a 50mm stroke, this 80mm bore model features a 3/8 inch port and M20x1.5 rod threads. The twin rods prevent rotation and can drive dual tools simultaneously. This SKU lacks a magnet, so it cannot accept CMSG or DMSG switches.

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 SAUD80X50 Is Used
Twin-Spindle Drilling
Drives two synchronized machining heads from opposite rod ends with identical 2268 N force to prevent spindle deflection.
Dual Transfer Pusher
Pushes alternating lanes of parts on a conveyor using both rod extensions, maintaining equal 50mm stroke timing.
Anti-Rotation Lift
Raises a 116 kg vertical platen without twisting, relying on the dual 25mm rods for geometric stability.
Is the Airtac SAUD Double Rod Cylinder SAUD80X50 the Right Cylinder?
Choose this 80mm bore delivering 2268 N each way when your mechanism requires strict anti-rotation guidance or twin tooling. If you need less force, step down to the 63mm bore (1402 N both ways); if you need more, there is no larger standard SAUD option. Mounting is limited to Basic, FA flange, or LB foot styles matching the AirTAC SC series. Because this specific SKU has no internal magnet, you cannot mount sensors. For load holding on air loss, add an external rod lock or pilot-operated check valve, as the adjustable 28mm cushions only decelerate near stroke end.
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 SAUD80X50 FAQ
The force is equal in both directions because a rod exits both ends. It outputs 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa.
No. This specific SKU is not built with a piston magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You would need an SAUD80X50-S variant for sensing.
