Airtac SAUD Double Rod Cylinder SAUD80X650
The AirTAC SAUD Double Rod Cylinder SAUD80X650 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 650mm 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 SAUD80X650
The AirTAC SAUD80X650 is a double-acting, double-rod profile cylinder. A Ø25 mm rod exits both ends of the hard-anodized aluminum extruded barrel, meaning both faces use the rod-side piston area. This yields identical push and pull thrust of 2268 N each way at 0.5 MPa. The unit is notably shorter than an ISO 15552 unit of the same bore.
With a 650 mm stroke, external guides are strongly recommended to prevent rod bending under side loads. Because this SKU lacks a magnet, it cannot host CMSG or DMSG switches. The 3/8 inch port drives the piston at 30-800 mm/s.

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 SAUD80X650 Is Used
Twin-Tool Machining
Drives two opposing machining heads simultaneously with equal 2268 N thrust in both directions, ensuring perfectly synchronized part processing.
Dual-End Transfer
Pushes a workpiece from one conveyor belt to another using both rod ends, allowing balanced momentum transfer without requiring a larger bore.
Is the Airtac SAUD Double Rod Cylinder SAUD80X650 the Right Cylinder?
Select this 80 mm bore (2268 N both ways at 0.5 MPa) when your mechanism requires strict anti-rotation guidance or needs to drive two tools at once. If you need less force, the 63 mm bore delivers 1402 N; if you need more, the 100 mm bore provides 3681 N. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. At 650 mm stroke, always use an external guide rail to absorb side loads. Note this non-magnetic SKU cannot accept 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 SAUD80X650 FAQ
Because the double rod occupies area on both piston faces, the thrust is equal in both directions. It generates 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 the 80 mm bore to cycle at 30-800 mm/s.
No, a plain SAUD cylinder will drift without live air. The adjustable 28 mm cushions only decelerate the piston near the stroke ends; they do not lock the load. For vertical load holding, you must fit an external rod lock or a pilot-operated check valve.
