Airtac SAUD Double Rod Cylinder SAUD80X70S
The AirTAC SAUD Double Rod Cylinder SAUD80X70S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 70mm 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 SAUD80X70S
The AirTAC SAUD80X70S is a double-acting, double-rod profile cylinder. A Ø25 mm rod protrudes from both ends of the hard-anodized aluminum barrel, meaning both faces use the rod-side piston area. This yields exactly 2268 N of thrust and pull at 0.5 MPa, with 3175 N at 0.7 MPa and 4082 N at 0.9 MPa. The 3/8" port and M20x1.5 rod thread handle the airflow for a 30-800 mm/s speed range.
Because the extruded profile body is shorter than a standard ISO 15552 unit of the same bore, it saves machine space. The -S suffix denotes a built-in piston magnet for CMSG, DMSG or EMSG switches.

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 SAUD80X70S Is Used
Twin-Spindle Machining
Drives two opposing machining heads simultaneously with equal 2268 N force, ensuring perfectly synchronized cutting cycles.
Anti-Rotation Transfer
Moves a wide gripper across a conveyor without twisting, using the dual rods to resist rotational torque during part handover.
Cam-Trippled Sorting
Uses the extended rear rod to physically trip a mechanical limit switch, providing a hardwired confirmation independent of the main sensor rail.
Is the Airtac SAUD Double Rod Cylinder SAUD80X70S the Right Cylinder?
Choose this 80 mm bore double-rod actuator when you need identical push and pull power, such as driving twin tooling or carrying a switch cam on the back rod. If your project needs less force, step down to the 63 mm bore (1402 N both ways); if you need more, the 100 mm bore provides 3681 N both ways. Mounting uses AirTAC SC-series FA flange or LB foot brackets. The -S magnet enables position sensing. For any stroke over 300 mm, fit external guide rails to prevent side-load wear on the seals.
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 SAUD80X70S FAQ
Because the 25 mm rod exits both ends, the push and pull forces are equal. It delivers 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa in both directions.
No. The adjustable 28 mm air cushions only decelerate the piston near the end caps; they do not lock. For secure load holding on air loss, install an external rod lock or pilot-operated check valve.
