Airtac SAUD Double Rod Cylinder SAUD80X400
The AirTAC SAUD Double Rod Cylinder SAUD80X400 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 400mm 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 SAUD80X400
The AirTAC SAUD80X400 is a double-acting, double-rod profile cylinder. A Ø25 mm piston rod extends from both ends, meaning push and pull forces are identical at 2268 N each way at 0.5 MPa. The extruded aluminum barrel keeps the body shorter than a standard ISO 15552 unit of the same bore. It features a 3/8 inch port and M20x1.5 rod threads.
With a 400 mm stroke, external guides are recommended to prevent rod bending under side loads. This non-magnet SKU cannot host position sensors. A plain cylinder drifts without live air; add an external rod lock for secure holding.

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 SAUD80X400 Is Used
Synchronized Transfer
Drives dual pusher arms on a conveyor line simultaneously, using the twin rods to keep the payload perfectly aligned without twisting.
Twin-Tool Machining
Powers two opposing machining heads from one central piston, ensuring both tools meet the workpiece with identical 2268 N force.
Guided Vertical Press
Lowers a pressing head with equal force both directions, relying on the dual rods to prevent binding during the 400 mm descent.
Is the Airtac SAUD Double Rod Cylinder SAUD80X400 the Right Cylinder?
Select this 80 mm bore delivering 2268 N equal force when you need synchronized motion or anti-rotation guidance. If you need less power, the 63 mm bore provides 1402 N both ways; for heavier duty, the 100 mm bore offers 3681 N. The twin rods suit twin-tool driving or carrying a cam on the back rod. Mounting is limited to Basic, FA, and LB types matching the AirTAC SC series. Because the 400 mm stroke is long, always use external guides to absorb side loads. Note this version lacks the -S magnet, so it cannot accept CMSG or DMSG switches.
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 SAUD80X400 FAQ
Because the rod exits both ends, force is equal in both directions: 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa. It uses a 3/8 inch port.
No. The air cushions only decelerate near stroke end; they do not lock the piston. If air is lost, the load drifts. Use an external rod lock or pilot-operated check valve for holding.
