Airtac SAUD Double Rod Cylinder SAUD80X45S
The AirTAC SAUD Double Rod Cylinder SAUD80X45S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 45mm 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 SAUD80X45S
The AirTAC SAUD80X45S is a double-acting, double-rod profile cylinder. A 25mm rod protrudes from both ends, meaning the push and pull forces are equal at 2268 N each way at 0.5 MPa. The extruded aluminum barrel keeps the body shorter than a standard ISO 15552 unit of the same bore. It features a 3/8 inch port and M20x1.5 rod thread.
Because the second rod exits the rear, you can mount a sensor cam directly on it. This unit includes the -S magnet for CMSG, DMSG or EMSG switches. Viton H seals 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 SAUD80X45S Is Used
Twin-Tool Stamping
Drives two synchronized forming tools from one piston, ensuring parallel contact without rotational twist.
Dual Transfer Pusher
Pushes a product forward while the rear rod simultaneously retracts a return actuator for a compact cell layout.
Cam-Triggered Sorting
Uses the protruding back rod to physically trip a limit switch, confirming full stroke position in harsh environments.
Is the Airtac SAUD Double Rod Cylinder SAUD80X45S the Right Cylinder?
Choose this 80mm bore if your application demands 2268 N of equal force in both directions over a short 45mm stroke. If you need less thrust, step down to the 63mm bore which provides 1402 N both ways. If you require more power, the 100mm bore yields 3681 N each way. A double rod is the right call when you need anti-rotation guidance, want to drive two tools at once, or need back-end sensing. Mounting is limited to Basic, FA flange, and LB foot brackets that match the AirTAC SC series. The -S option enables switch sensing. For this 45mm stroke side loads are minimal, but always use external guides for any stroke over 300mm.
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 SAUD80X45S FAQ
The force is equal in both directions because it is a double-rod design. 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, a plain double-rod cylinder drifts without live air. The adjustable 28mm cushions only decelerate the piston near the end caps. To hold a load securely, install an external rod lock or a pilot-operated check valve.
