Airtac SAUD Double Rod Cylinder SAUD80X35
The AirTAC SAUD Double Rod Cylinder SAUD80X35 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 35mm 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 SAUD80X35
The AirTAC SAUD80X35 is a double-acting, double-rod profile cylinder with a 80 mm bore and 35 mm stroke. A Ø25 mm piston rod protrudes from both ends, meaning both faces use the rod-side area. This yields exactly 2268 N of output force at 0.5 MPa in both directions. The extruded aluminium barrel keeps the unit shorter than an ISO 15552 cylinder of the same bore. It features a 3/8 inch port and M20x1.5 rod threads.
Because the rod exits both ends, you gain mechanical anti-rotation guidance and can drive twin tooling simultaneously. This specific SKU lacks a magnet, so it cannot accept CMSG or DMSG switches. If your environment hits 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 SAUD80X35 Is Used
Twin-Spindle Drilling
Drives two opposing drill heads simultaneously with matched advance pressure, utilizing the equal push and pull force to maintain tool alignment.
Dual Transfer Pusher
Pushes a workpiece forward on the extend stroke while retracting a secondary stop or diverter on the return stroke for continuous flow.
Balanced Lift Fixture
Lifts a 116 kg vertical payload using both rod ends to keep the platform perfectly level without twisting during travel.
Is the Airtac SAUD Double Rod Cylinder SAUD80X35 the Right Cylinder?
Select this 80 mm bore if you need 2268 N of equal bidirectional force at 0.5 MPa. Stepping down, the 63 mm bore provides 1402 N. Stepping up, the 100 mm bore yields 3681 N. A double rod is the right call when your mechanism requires anti-twist stability or needs to mount a sensor cam on the back rod—though this non-magnet version cannot hold a switch. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. At 35 mm stroke, side loading is minimal, but always guide the external load to prevent 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 SAUD80X35 FAQ
The force is equal in both directions because the rod exits both ends. It provides 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 both chambers.
No. The air cushions only decelerate the piston near the stroke ends and do not act as a brake. For load holding on air loss, you must install an external rod lock or a pilot-operated check valve.
