Airtac SAUD Double Rod Cylinder SAUD80X350S
The AirTAC SAUD Double Rod Cylinder SAUD80X350S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 350mm 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 SAUD80X350S
The AirTAC SAUD80X350S is a double-acting, double-rod profile cylinder. A rod exits both ends, meaning both faces use the rod-side piston area. This yields equal force in both directions, delivering 2268 N each way at 0.5 MPa. The extruded aluminium profile barrel keeps the unit shorter than a standard ISO 15552 cylinder of the same bore. It features a 3/8 inch port, an M20x1.5 rod thread, and 28 mm adjustable air cushions at both ends.
This model includes the -S piston magnet for CMSG, DMSG, or EMSG switches. The dual-rod design provides anti-rotation guidance and lets you mount a sensor cam on the back rod. A Viton H seal option extends 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 SAUD80X350S Is Used
Dual Transfer Pushers
Drives two synchronized pusher plates from one piston to move cartons on parallel conveyor lanes without twisting.
Gripper Synchronization
Provides perfectly matched opposing motion for clamping irregular metal parts during machining operations.
Is the Airtac SAUD Double Rod Cylinder SAUD80X350S the Right Cylinder?
This 80 mm bore provides 2268 N of equal push and pull force at 0.5 MPa. If you need less power, step down to the 63 mm bore for 1402 N. If your application requires more, the 100 mm bore offers 3681 N. Choose a double-rod cylinder when you need strict anti-rotation resistance, synchronized twin tooling, or a back rod to trip a switch. Mounting is limited to Basic, FA, and LB styles, matching the AirTAC SC series. Because the stroke is 350 mm, add external guide rails to prevent rod bending under side loads. The -S magnet allows solid-state or reed sensor tracking.
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 SAUD80X350S FAQ
The force is equal in both directions because it is a double-rod cylinder. 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.
No. The adjustable 28 mm air cushions only decelerate the piston near the end caps; they do not lock the load. For secure holding on air loss, install an external rod lock or a pilot-operated check valve.
