Airtac SAUD Double Rod Cylinder SAUD80X650S
The AirTAC SAUD Double Rod Cylinder SAUD80X650S 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 SAUD80X650S
The AirTAC SAUD80X650S is a double-acting, double-rod profile cylinder. A piston rod exits both ends, meaning both faces use the identical rod-side area. This yields equal push and pull force of 2268 N each way at 0.5 MPa. The extruded hard-anodized aluminum barrel keeps the unit shorter than an ISO 15552 cylinder of the same bore. The 3/8 inch port feeds the 80 mm bore, operating at 30-800 mm/s.
With a 650 mm stroke, external guides should support the load to prevent rod bending under side loads. The built-in magnet (-S) allows CMSG, DMSG, or EMSG switches to mount directly for position sensing. High-temperature Viton H seals 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 SAUD80X650S Is Used
Synchronized Transfer
Drives opposing conveyor diverter arms simultaneously from one unit, ensuring perfectly timed material routing without twist.
Twin-Spindle Lifting
Lifts and lowers dual machining heads with equal push and pull thrust, maintaining parallel tool alignment.
Rear-Cam Sensing
Uses the extended back rod to trip a CMSG or DMSG switch directly, confirming end-of-stroke position in tight cells.
Is the Airtac SAUD Double Rod Cylinder SAUD80X650S the Right Cylinder?
Select this 80 mm bore when your application demands identical force in both directions, delivering 2268 N at 0.5 MPa. Stepping down, the 63 mm bore provides 1402 N both ways, while the 100 mm bore offers 3681 N if you need higher thrust. The double-rod design is the right call for anti-rotation guidance, driving twin tooling, or mounting a switch cam on the back rod. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. Because the 650 mm stroke is long, always use external load guides to prevent rod bending. The -S magnet enables electronic or reed sensing.
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 SAUD80X650S FAQ
Because the double 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 supplies air to the 80 mm bore.
No, the adjustable 28 mm air cushions only decelerate the piston near stroke end. The unit drifts without live air. For load holding, install an external rod lock or a pilot-operated check valve.
