Airtac SAUD Double Rod Cylinder SAUD80X250
The AirTAC SAUD Double Rod Cylinder SAUD80X250 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 SAUD80X250
The AirTAC SAUD80X250 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 piston area. This yields equal push and pull force of 2268 N each way at 0.5 MPa. The unit is shorter than a standard ISO 15552 cylinder of the same bore and uses a 3/8" port with an M20x1.5 rod thread.
Because both ends carry a rod, the design provides inherent anti-rotation guidance and lets you mount twin tooling or a switch cam on the back side. This specific SKU lacks a magnet, so it cannot accept CMSG, DMSG or EMSG sensors. For high-heat duties up to 150 C, specify the Viton H seal option.

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 SAUD80X250 Is Used
Synchronized Transfer
Drives two parallel conveyor diverters at once using both rod ends to keep the transfer perfectly synchronized without twisting.
Balanced Vertical Lift
Raises and lowers a 116 kg work platform with equal force both ways, ensuring smooth deceleration via the 28 mm adjustable cushions.
Twin Tool Actuation
Powers opposing forming tools simultaneously from a single compact profile body, saving space compared to two separate cylinders.
Is the Airtac SAUD Double Rod Cylinder SAUD80X250 the Right Cylinder?
Choose this 80 mm bore when your application demands 2268 N of equal force in both directions over a 250 mm stroke. If you need less thrust, the neighbouring 63 mm bore provides 1402 N both ways; if you need more, step up to the 100 mm bore for 3681 N. A double-rod configuration is the right call for synchronized lifting, non-rotating anti-twist loads, or driving two tools at once. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. At 250 mm stroke, keep an external guide to absorb any lateral side loads and prevent rod binding. Note this non-magnetic version cannot host position sensors.
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 SAUD80X250 FAQ
The force is equal both ways because the Ø25 mm rod exits both ends. It delivers 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa for both extension and retraction. The 3/8" port feeds both chambers.
No. The adjustable air cushions only decelerate the piston near the stroke ends; they do not lock the load. If air is lost, the piston will drift. Use an external rod lock or a pilot-operated check valve to hold a suspended load safely.
