Airtac SAUD Double Rod Cylinder SAUD80X210S
The AirTAC SAUD Double Rod Cylinder SAUD80X210S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 210mm 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 SAUD80X210S
The AirTAC SAUD80X210S is a double-acting, double-rod profile cylinder. A 25mm rod exits both ends of the hard-anodized aluminum extrusion, meaning both faces use the rod-side area. This yields equal force in both directions at 2268 N each way at 0.5 MPa. The 3/8 inch port and M20x1.5 rod thread handle the airflow and mounting. It runs at 30-800 mm/s with adjustable 28mm cushions at each end.
This compact unit is shorter than an ISO 15552 cylinder of the same 80mm bore. The -S suffix denotes a built-in piston magnet for CMSG, DMSG, or EMSG switches. A high-temp Viton H seal can extend operation to 150 C.

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 SAUD80X210S Is Used
Twin-Spindle Drilling
Drives two synchronized machining heads from one piston, ensuring perfectly balanced feed rates and equal clamping force on both strokes.
Dual Transfer Pusher
Pushes parts alternately from opposite sides of a conveyor lane using the protruding rods at both ends, saving space and cycle time.
Cam-Triggered Sorting
Uses the rear protruding rod to physically trip an external limit switch or carry a magnetic sensor cam, confirming stroke completion without extra space.
Is the Airtac SAUD Double Rod Cylinder SAUD80X210S the Right Cylinder?
Select this 80mm bore model when you need identical push and pull power. If your project requires less force, step down to the 63mm bore which provides 1402 N both ways at 0.5 MPa. If you need more power, the 100mm bore offers 3681 N both ways. The double-rod architecture is the right call for anti-rotation guidance, driving twin tooling, or mounting a sensor cam on the back rod. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. At a 210mm stroke, side-load is minimal, but always use external guide rails for longer travels. Remember that a standard cylinder drifts without air pressure; use an external rod lock or pilot-operated check valve for secure load holding.
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 SAUD80X210S FAQ
Because the 25mm rod exits both ends, the force is equal in both directions. 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.
The S indicates a built-in piston magnet. This allows you to mount CMSG, DMSG, or EMSG electronic or reed switches directly onto the profile barrel for position sensing.
