Airtac SAUD Double Rod Cylinder SAUD80X120S
The AirTAC SAUD Double Rod Cylinder SAUD80X120S 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 SAUD80X120S
The AirTAC SAUD80X120S is a double-acting, double-rod profile cylinder. A Ø25 mm rod protrudes from both ends of the hard-anodized aluminum extrusion, meaning both faces use the rod-side area. This yields exactly 2268 N of thrust and pull 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.
Because the rod exits the back cap, you can mount a switch cam directly on it for end-of-stroke signaling. The -S suffix confirms a built-in piston magnet ready for CMSG, DMSG, or EMSG sensors. This profile body is noticeably shorter than a standard ISO 15552 unit of the same bore.

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 SAUD80X120S Is Used
Twin-Spindle Drilling
Drives two opposing drill heads simultaneously with equal 2268 N force, ensuring balanced feed rates and preventing spindle twist.
Dual-End Transfer Pusher
Pushes a workpiece forward while extending a rear cam to trip a mechanical limit switch, sequencing the next conveyor stage.
Guided Lift Platform
Raises a 116 kg vertical load using both rods for inherent anti-rotation stability, avoiding the need for external linear bearings.
Is the Airtac SAUD Double Rod Cylinder SAUD80X120S the Right Cylinder?
Choose this 80 mm bore when you need 2268 N of equal force in both directions. If your application requires less thrust, step down to the 63 mm bore delivering 1402 N both ways. If you need more power, the 100 mm bore provides 3681 N symmetrically. A double-rod design is the right call for anti-rotation guidance, driving twin tooling, or mounting a rear sensor cam. Mounting is limited to Basic, FA flange, and LB foot brackets, matching the AirTAC SC series footprint. The -S magnet enables electronic position sensing. For this 120 mm stroke, external load guides are recommended to prevent side-load binding.
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 SAUD80X120S FAQ
Force is equal in both directions because the rod exits both ends. It generates 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa. The 3/8 inch port supplies air to achieve these symmetric thrust figures.
No, a plain double-rod cylinder drifts without live air. The adjustable 28 mm cushions only decelerate the piston near stroke ends. For secure load holding, install an external rod lock or a pilot-operated check valve.
