Airtac SAUD Double Rod Cylinder SAUD80X120
The AirTAC SAUD Double Rod Cylinder SAUD80X120 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 120mm 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 SAUD80X120
The AirTAC SAUD80X120 is a double-acting, double-rod profile cylinder. A 25mm rod exits both ends, meaning push and pull forces are equal at 2268 N each way at 0.5 MPa. The extruded aluminium barrel keeps the body shorter than an ISO 15552 unit of the same bore. It uses a 3/8 inch port and an M20x1.5 rod thread.
The twin-rod design offers excellent anti-rotation guidance and lets you mount tooling on both ends simultaneously. Without the -S magnet option, this specific SKU cannot accept magnetic 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 SAUD80X120 Is Used
Twin-Tool Stamping
Drives two separate forming tools simultaneously from opposite rod ends, ensuring perfectly synchronized press cycles without torsional deflection.
Dual Transfer Pusher
Indexes products on parallel conveyor lanes using both rod extensions, maintaining parallel alignment during high-speed sorting operations.
Anti-Rotation Gripper
Handles heavy mechanical parts by using the inherent torsional rigidity of the dual rods to prevent jaw rotation during clamping.
Is the Airtac SAUD Double Rod Cylinder SAUD80X120 the Right Cylinder?
Choose this 80mm bore if your application requires 2268 N of equal force in both directions over a 120mm stroke. Stepping down to the 63mm bore yields 1402 N, while the 100mm bore offers 3681 N at 0.5 MPa. A double-rod configuration is the right call when you need synchronized twin tooling, strict anti-twist guidance, or a back-end cam. Mounting is limited to Basic, FA flange, and LB foot brackets, matching the AirTAC SC series. Because the 120mm stroke is under 300mm, side-load guide concerns are minimal. Remember that this non-magnet SKU cannot host CMSG or DMSG switches.
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 SAUD80X120 FAQ
Because the 25mm rod exits both ends, the force is equal in both directions: 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa. It uses a 3/8 inch port.
No, the adjustable 28mm air cushions only decelerate the piston near the stroke ends. For secure load holding on air loss, you must fit an external rod lock or a pilot-operated check valve.
