Airtac SAUD Double Rod Cylinder SAUD80X280S
The AirTAC SAUD Double Rod Cylinder SAUD80X280S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 280mm 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 SAUD80X280S
The AirTAC SAUD80X280S is a double-acting, double-rod profile cylinder. A Ø25 mm rod protrudes from both ends, meaning both faces use the rod-side area. This yields equal push and pull force of 2268 N each way at 0.5 MPa. The extruded aluminium barrel is shorter than an ISO 15552 cylinder of the same bore.
This 80 mm bore unit features a 3/8" port and adjustable 28 mm air cushions at both ends. The built-in magnet (-S) supports CMSG, DMSG and EMSG switches. For high heat, Viton H seals raise the limit 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 SAUD80X280S Is Used
Twin-Tool Machining
Drives two opposing tools simultaneously with identical 2268 N force, keeping cycle times balanced.
Anti-Rotation Transfer
Moves parts along a conveyor without rotational twist, using the dual rods for strict linear guidance.
Back-End Switch Cam
Uses the rear protruding rod to trip an external limit switch, confirming full retraction independently.
Is the Airtac SAUD Double Rod Cylinder SAUD80X280S the Right Cylinder?
Select this 80 mm bore model for anti-rotation guidance, twin-tool driving, or mounting a sensor cam on the back rod. It delivers 2268 N both ways. If you need less force, the 63 mm bore provides 1402 N; if you need more, the 100 mm bore yields 3681 N. Mounting is limited to Basic, FA and LB types, matching the AirTAC SC series. With a 280 mm stroke, ensure external guide rails carry any side loads 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 SAUD80X280S 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" port supplies air to both chambers equally.
No, a plain SAUD cylinder drifts without live air. The adjustable cushions only decelerate the piston near the stroke ends. For secure load holding, install an external rod lock or pilot-operated check valve.
