Airtac SAUD Double Rod Cylinder SAUD80X500S
The AirTAC SAUD Double Rod Cylinder SAUD80X500S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 500mm 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 SAUD80X500S
The AirTAC SAUD80X500S 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 push and pull force of 2268 N each way at 0.5 MPa. The extruded aluminum profile barrel is shorter than an ISO 15552 cylinder of the same bore.
This unit includes a built-in piston magnet (-S) for CMSG, DMSG, or EMSG switches. It features a 3/8" port, M20x1.5 rod thread, and adjustable air cushions at both ends. A Viton H seal option can raise the operating temperature 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 SAUD80X500S Is Used
Twin-Tool Stamping
Drives two synchronized forming tools from opposite rod ends to double production output in a single stroke.
Anti-Rotation Diverter
Uses the dual-rod geometry to prevent mechanical twist while pushing heavy packages across a belt line.
Cam-Triggered Cutting
Mounts a switch cam on the rear protruding rod to confirm blade position before initiating the next cut.
Is the Airtac SAUD Double Rod Cylinder SAUD80X500S the Right Cylinder?
Select this 80 mm bore when you need 2268 N of equal force in both directions. If less force is required, the 63 mm bore delivers 1402 N both ways. If more is needed, the 100 mm bore provides 3681 N both ways. A double rod is ideal for anti-rotation guidance, driving twin tooling, or mounting a sensor cam on the back end. Mounting is limited to Basic, FA, and LB types, matching the AirTAC SC series. Because the stroke is 500 mm, use external guides to prevent rod bending under side loads. The -S magnet enables position 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 SAUD80X500S FAQ
Because the rod exits both ends, the force is equal in both directions. It provides 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa. The 3/8" port supplies air to both chambers.
No. A plain double-rod cylinder will drift if air pressure drops or the valve is centered. The adjustable cushion only decelerates the piston near the stroke ends and does not act as a brake. Use an external rod lock or pilot-operated check valve for secure load holding.
