Airtac SAUD Double Rod Cylinder SAUD80X180
The AirTAC SAUD Double Rod Cylinder SAUD80X180 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 180mm 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 SAUD80X180
The AirTAC SAUD80X180 is a double-acting, double-rod profile cylinder. A Ø25 mm rod protrudes from both ends of the hard-anodized aluminum barrel, meaning both faces use the rod-side area. Output is equal in both directions at 2268 N each way at 0.5 MPa. The 3/8 inch port and M20x1.5 rod thread handle robust flow.
Because the extruded profile body lacks external struts, it is shorter than an ISO 15552 cylinder of the same bore. This SKU has no magnet, so it cannot take a magnetic switch. The 28 mm adjustable air cushions at both ends only decelerate the piston near stroke end; they do not lock the load. For sustained holding on air loss, fit an external rod lock or pilot-operated check valve.

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 SAUD80X180 Is Used
Twin-Tool Machining
Drives two opposing machining heads simultaneously with identical 2268 N force, ensuring balanced material removal on both sides of a workpiece.
Anti-Rotation Divert
Pushes a diverting arm across a belt line without twisting, using the dual rods to maintain precise angular alignment during the 180 mm travel.
Mechanical Cam Trip
Uses the protruding back rod to physically strike a limit switch at stroke end, ideal for rugged environments where electronic sensors are unsuitable.
Is the Airtac SAUD Double Rod Cylinder SAUD80X180 the Right Cylinder?
Choose this 80 mm bore delivering 2268 N equal force both ways at 0.5 MPa. Stepping down, the 63 mm bore provides 1402 N both ways; stepping up, the 100 mm bore yields 3681 N. A double rod is the right call when you need anti-rotation guidance, twin tooling on one piston, or a back rod to trip a mechanical switch. Mounting is limited to Basic, FA flange, and LB foot brackets compatible with the AirTAC SC series. For the 180 mm stroke, external guide rails are advised to prevent side-load sag. A Viton H seal option raises the operating ceiling to 150 C.
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 SAUD80X180 FAQ
Force is equal both ways because both faces have a rod. It produces 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa in both extend and retract directions.
No. This specific SKU lacks a piston magnet, so it cannot operate magnetic switches like CMSG or DMSG. You must use the back rod to trip an external mechanical limit switch.
