Airtac SAUD Double Rod Cylinder SAUD80X425
The AirTAC SAUD Double Rod Cylinder SAUD80X425 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 425mm 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 SAUD80X425
The AirTAC SAUD80X425 is a double-acting, double-rod profile cylinder. A Ø25 mm rod exits both ends of the hard-anodized aluminum extruded barrel, meaning both faces use the rod-side piston area. This yields exactly 2268 N of output force in both directions at 0.5 MPa. The 3/8 inch port and M20x1.5 rod thread handle robust airflow and mounting.
Because both ends carry a rod, the unit provides anti-rotation guidance and can drive twin tooling simultaneously. The extruded profile is shorter than an ISO 15552 cylinder of the same bore. Note this SKU lacks a magnet, so it cannot accept CMSG or DMSG sensors.

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 SAUD80X425 Is Used
Dual-End Transfer
Drives two synchronized pushers on a single conveyor line using both rod ends to maintain equal timing.
Anti-Rotation Clamp
Applies 2268 N of clamping force without twisting, thanks to the inherent guidance of the double-rod design.
Symmetric Lifter
Lifts palletized loads vertically with equal force both ways, keeping the payload stable during transit.
Is the Airtac SAUD Double Rod Cylinder SAUD80X425 the Right Cylinder?
Select this 80 mm bore if your application requires equal push and pull force, such as 2268 N both ways at 0.5 MPa. If you need less force, the 63 mm bore delivers 1402 N both ways; if you need more, the 100 mm bore offers 3681 N both ways. A double rod is the right call for anti-rotation stability, twin tooling, or mounting a switch cam on the back rod. Mounting is limited to Basic, FA, and LB types, compatible with the AirTAC SC series. Because the 425 mm stroke is long, use external guides to prevent rod bending under side loads. This SKU has no magnet (-S) and cannot take sensors.
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 SAUD80X425 FAQ
The force is equal in both directions because it is a double-rod cylinder. It outputs 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa. It never provides a larger single-rod push value.
No. A plain SAUD cylinder does not hold a load on air loss; the piston drifts and the adjustable 28 mm air cushions only decelerate near stroke end. For a held load, use an external rod lock or a pilot-operated check valve.
