Airtac SAUD Double Rod Cylinder SAUD80X50S
The AirTAC SAUD Double Rod Cylinder SAUD80X50S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 50mm 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 SAUD80X50S
The AirTAC SAUD80X50S is a double-acting, double-rod profile cylinder. A Ø25 mm rod exits both ends of the hard-anodized extruded aluminum barrel, meaning both faces use the rod-side piston area. This yields equal push and pull force of 2268 N each way at 0.5 MPa. The 3/8 inch port supplies air, while M20x1.5 rod threads and 28 mm adjustable cushions manage the load.
Because both chambers lose identical rod area, output is perfectly symmetrical. This compact profile body is shorter than an ISO 15552 cylinder of the same bore. The built-in magnet (-S) supports CMSG, DMSG, or EMSG switches. A high-temperature Viton H seal option can extend operation from -20 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 SAUD80X50S Is Used
Twin-Tool Stamping
Drives two synchronized forming tools from one piston, ensuring parallel contact and equal 2268 N clamping force on both ends.
Anti-Rotation Transfer
Moves a gripper across a machining cell without twist, using the dual rods to resist torsional deflection during rapid traverses.
Cam-Triggered Cutting
Uses the protruding back rod to trip an external limit switch, confirming blade position before initiating the next packaging cycle.
Is the Airtac SAUD Double Rod Cylinder SAUD80X50S the Right Cylinder?
Choose this 80 mm bore when you need 2268 N of equal bidirectional force at 0.5 MPa. Stepping down to the 63 mm bore yields 1402 N both ways, while the 100 mm bore provides 3681 N. The double-rod architecture is ideal for anti-rotation guidance, driving twin tooling, 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. The -S magnet enables position sensing. For this 50 mm stroke side-load is minimal, but any stroke over 300 mm requires external guide rails 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 SAUD80X50S FAQ
Force is equal both ways because of the double-rod design. It produces 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa in both extend and retract directions.
No. The 28 mm adjustable cushions only decelerate the piston near stroke end; they do not lock the rod. For load holding on air loss, install an external rod lock or pilot-operated check valve.
