Airtac SAUD Double Rod Cylinder SAUD80X475S
The AirTAC SAUD Double Rod Cylinder SAUD80X475S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 475mm 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 SAUD80X475S
The AirTAC SAUD80X475S is a double-acting, double-rod profile cylinder. A 25mm rod protrudes from both ends of the hard-anodized aluminum extruded barrel, meaning push and pull forces are identical at 2268 N each way at 0.5 MPa. This compact profile body is notably shorter than a standard ISO 15552 unit of the same bore, and the 3/8 inch port drives a 30-800 mm/s speed range.
Because the -S suffix denotes a built-in piston magnet, you can mount CMSG, DMSG, or EMSG switches directly onto the profile slot. The equal force makes it ideal for non-rotating anti-twist guidance or carrying a sensor cam on the back rod. The standard TPU seals handle -20 to +70 C, while a Viton H option extends this to 150 C.

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 SAUD80X475S Is Used
Twin-Tool Transfer
Drives two opposing grippers simultaneously with equal force in both directions for balanced part transfer between machining stations.
Synchronized Lift Station
Raises and lowers a 116kg vertical payload using the back rod as a stable cam surface to trigger CMSG position switches.
Anti-Rotation Stopper
Uses the dual-rod geometry to prevent mechanical twist during 475mm extended positioning of heavy workholding fixtures.
Is the Airtac SAUD Double Rod Cylinder SAUD80X475S the Right Cylinder?
Select this 80mm bore when you need matched push and pull forces for twin-tool or synchronized lifting duties. If you need less force, the 63mm bore delivers 1402 N both ways; if you need more, the 100mm bore provides 3681 N both ways at 0.5 MPa. Mounting is limited to Basic, FA flange, and LB foot styles, sharing compatibility with the AirTAC SC series. The -S magnet enables electronic or reed sensing. Since the 475mm stroke is relatively long, always use external guide rails to prevent rod bending and side-load damage.
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 SAUD80X475S FAQ
The force is equal in both directions because the 25mm rod exits both ends. It outputs 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa. The 3/8 inch port and 28mm adjustable cushions at each end manage the 30-800 mm/s speed range.
No, a plain double-rod cylinder drifts when air is lost or the valve is centered; the adjustable cushions only decelerate the piston near the stroke ends. To maintain a vertical position, you must add an external rod lock or a pilot-operated check valve.
