Airtac SAUD Double Rod Cylinder SAUD80X700
The AirTAC SAUD Double Rod Cylinder SAUD80X700 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 700mm 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 SAUD80X700
The AirTAC SAUD80X700 is a double-acting, double-rod profile cylinder with a 80 mm bore and 700 mm stroke. A rod exits both ends, meaning both faces use the rod-side piston area. This makes the push and pull force equal, delivering 2268 N each way at 0.5 MPa. The extruded aluminum profile barrel keeps the overall body shorter than a standard ISO 15552 unit of the same bore.
This SKU has no internal magnet, so it cannot carry magnetic switches like the CMSG or DMSG series. The 3/8 inch port and M20x1.5 rod thread handle robust flow. For thermal extremes, Viton H seals raise the operating ceiling to 150 C. Note that the 28 mm adjustable cushions only decelerate the piston near stroke end; they do not hold the load if air pressure drops.

| 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 SAUD80X700 Is Used
Dual-Tool Transfer
Drives two synchronized work tools from opposite rod ends to push and pull parts along a manufacturing line.
Cam-Actuated Press
Uses the extended back rod to physically trip a mechanical limit switch at the bottom of the 700 mm descent.
Is the Airtac SAUD Double Rod Cylinder SAUD80X700 the Right Cylinder?
When sizing this double-rod unit, compare it against neighboring bores: the 63 mm version yields 1402 N both ways, while the 100 mm bore provides 3681 N. Choose the 80 mm bore when you need substantial equal force for anti-rotation guidance, twin-tool driving, or mounting a sensor cam on the back rod. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. Because this is a 700 mm stroke, external guides are strongly recommended to prevent rod bending and absorb side loads. To add sensing, select the -S magnet option instead of this plain model. For load holding on air loss, install an external rod lock or pilot-operated check valve.
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 SAUD80X700 FAQ
Because it is a double-rod cylinder, the force is equal in both directions. 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 equally.
No, this specific SKU lacks an internal magnet and cannot take CMSG or DMSG switches. You must select the SAUD80X700-S variant for magnetic sensing, or use the back rod to trip an external mechanical switch.
