Airtac SAUD Double Rod Cylinder SAUD80X30S
The AirTAC SAUD Double Rod Cylinder SAUD80X30S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 30mm 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 SAUD80X30S
The AirTAC SAUD80X30S is a double-acting, double-rod profile cylinder. A 25 mm rod exits both ends of the hard-anodized aluminum extrusion, meaning both faces use the rod-side area. Push and pull force are identical at 2268 N each way at 0.5 MPa. The body is shorter than an ISO 15552 unit of the same bore, and it uses a 3/8" port.
Because the rod protrudes at the back, you can mount a sensor cam directly on it for CMSG, DMSG, or EMSG switches (the -S suffix confirms the piston magnet is fitted). For high-heat environments up to 150 C, specify the Viton H seal option.

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 SAUD80X30S Is Used
Twin-Spindle Drilling
Drives two synchronized machining spindles from one piston, ensuring both holes are bored simultaneously without rotational twist.
Dual Pusher Diverter
Pushes parallel items on a conveyor belt simultaneously using tooling attached to both rod ends for matched timing.
Cam-Actuated Sorting
Uses the rear protruding rod to trip an external CMSG or DMSG switch cam, confirming full extension in a sorting gate.
Is the Airtac SAUD Double Rod Cylinder SAUD80X30S the Right Cylinder?
Choose this 80 mm bore if you need 2268 N of equal bidirectional force. Stepping down, the 63 mm bore provides 1402 N both ways. Stepping up, the 100 mm bore yields 3681 N. A twin-rod design is the right call when you need anti-rotation guidance, want to drive two tools at once, or need back-end switch actuation. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. At 30 mm stroke, side-load risks are minimal, but always guide external loads to prevent binding. Remember that a plain cylinder drifts without live air; use an external rod lock for held loads.
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 SAUD80X30S 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.
No, the air cushions only decelerate the piston near the stroke end and do not lock the load. If power fails, the piston drifts. For secure load holding, install an external rod lock or a pilot-operated check valve.
