Airtac SAUD Double Rod Cylinder SAUD80X55S
The AirTAC SAUD Double Rod Cylinder SAUD80X55S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 55mm 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 SAUD80X55S
The AirTAC SAUD80X55S is a double-acting, double-rod profile cylinder. A Ø25 mm rod exits both ends of the hard-anodized aluminum extruded barrel, meaning both faces use the rod-side area. This yields an identical output of 2268 N each way at 0.5 MPa. The 3/8 inch port feeds the chambers, and the overall body is shorter than an ISO 15552 unit of the same bore.
Because the twin rods resist torsional twist, this model suits non-rotating and synchronized twin-tool tasks. The -S suffix indicates 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 SAUD80X55S Is Used
Twin-Tool Stamping
Drives two synchronized forming tools from one piston, ensuring parallel contact without torsional deflection.
Anti-Rotation Lifter
Lifts vertical loads up to 116 kg with equal push and pull force, using the dual rods to prevent mechanical twist.
Cam-Trip Switching
Uses the protruding back rod as a mechanical cam to physically trigger external limit switches during motion.
Is the Airtac SAUD Double Rod Cylinder SAUD80X55S the Right Cylinder?
Choose this 80 mm bore when you need 2268 N of equal push and pull force. Stepping down, the 63 mm bore provides 1402 N both ways. Stepping up, the 100 mm bore yields 3681 N both ways. A double-rod design is the right call for anti-rotation guidance, driving two tools at once, or mounting a switch cam on the back rod. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. The -S magnet enables position sensing. For this 55 mm stroke, side loads are minimal, but always use external guides for any stroke reaching 300 mm or more.
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 SAUD80X55S FAQ
The force is equal in both directions because the Ø25 mm 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. It operates on a 3/8 inch port at speeds of 30-800 mm/s.
No. A plain double-rod cylinder drifts without live air, as the adjustable 28 mm cushions only decelerate the piston near stroke end. For secure load holding, install an external rod lock or a pilot-operated check valve.
