Airtac SAUD Double Rod Cylinder SAUD80X850
The AirTAC SAUD Double Rod Cylinder SAUD80X850 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 850mm 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 SAUD80X850
The AirTAC SAUD80X850 is a double-acting, double-rod profile cylinder. A Ø25 mm rod protrudes from both ends of the hard-anodized extruded aluminum barrel, meaning both faces use the rod-side area. This yields exactly 2268 N of output force at 0.5 MPa in both directions. The unit is shorter than a standard ISO 15552 cylinder of the same bore.
Because the rod exits the back, you can mount a sensor cam or drive twin tools simultaneously. This SKU lacks a magnet, so it cannot accept CMSG or DMSG switches. The 3/8" port and 28 mm adjustable cushions manage 30-800 mm/s speeds.

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 SAUD80X850 Is Used
Twin-Tool Stamping
Drives two forming tools simultaneously from opposite rod ends, ensuring perfectly synchronized press strokes.
Anti-Rotation Lifting
The dual rods prevent piston twist during vertical elevation of heavy jigs, maintaining precise alignment.
Cam Trip Mechanism
Uses the rear rod extension to mechanically trip an external limit valve at mid-stroke without onboard sensors.
Is the Airtac SAUD Double Rod Cylinder SAUD80X850 the Right Cylinder?
Choose this 80 mm bore if you need 2268 N equal force both ways. Stepping down, the 63 mm bore provides 1402 N; stepping up, the 100 mm bore offers 3681 N at 0.5 MPa. A double rod is the right call for anti-rotation guidance or twin-tool setups. Mounting is limited to Basic, FA, and LB types compatible with the AirTAC SC series. At 850 mm, this long stroke requires external guides to prevent rod bending under side loads. Without a magnet, this SKU cannot host sensors.
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 SAUD80X850 FAQ
The force is equal both ways due to the double-rod design. It delivers 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa. The 3/8" port feeds both chambers equally.
No. A plain SAUD cylinder drifts without live air, as the 28 mm cushions only decelerate near the stroke ends. For load holding, install an external rod lock or pilot-operated check valve.
