Airtac SAUD Double Rod Cylinder SAUD80X250S
The AirTAC SAUD Double Rod Cylinder SAUD80X250S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 250mm 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 SAUD80X250S
The AirTAC SAUD80X250S is a double-acting, double-rod profile cylinder. A Ø25 mm rod protrudes from both ends of the hard-anodized extruded aluminum barrel, meaning both faces use the rod-side area. This yields exactly 2268 N of thrust and pull at 0.5 MPa, ensuring perfectly balanced motion. The 3/8" port and M20x1.5 rod thread handle robust pneumatic flows.
Because the body is an extruded profile rather than a standard assembly, it is shorter than an equivalent ISO 15552 unit while retaining adjustable 28 mm cushions at both ends. 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 SAUD80X250S Is Used
Twin-Spindle Drilling
Drives two synchronized machining heads from one piston, using the equal both-ways force to retract both tools cleanly without twist.
Dual Transfer Pusher
Pushes a part forward on the main stroke while actuating a diverter arm on the back rod, keeping cycle times perfectly in phase.
Vertical Lift Gate
Raises a 116 kg safety gate using the balanced extension and retraction forces, preventing sagging drift during continuous operation.
Is the Airtac SAUD Double Rod Cylinder SAUD80X250S the Right Cylinder?
When sizing this 80 mm bore, compare it both ways: the 63 mm bore delivers 1402 N, while the 100 mm bore provides 3681 N, both equal in extension and retraction. Select this double-rod variant when your mechanism requires strict anti-rotation guidance, needs to drive two tools simultaneously, or uses the back rod to trip a switch. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. At a 250 mm stroke, external side-load guides are recommended to protect the seals. The -S magnet allows solid-state or reed sensors to track position directly.

- ✓ 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 SAUD80X250S FAQ
The force is equal in both directions because a 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. The 3/8" port supplies the air required for these thrust and pull figures.
No. The adjustable 28 mm cushions only decelerate the piston near the stroke ends; they do not lock the position. If air is lost or the valve is centered, the load will drift. For secure holding, install an external rod lock or a pilot-operated check valve.
