Airtac SAUD Double Rod Cylinder SAUD100X400S
The AirTAC SAUD Double Rod Cylinder SAUD100X400S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 400mm stroke, 1/2" 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 SAUD100X400S
The AirTAC SAUD100X400S is a double-acting, double-rod profile cylinder. A rod exits both ends, meaning both faces use the rod-side area. This yields equal push and pull force of 3681 N each way at 0.5 MPa. The extruded hard-anodized aluminum barrel is shorter than an ISO 15552 cylinder of the same 100 mm bore.
This unit includes a -S piston magnet for CMSG, DMSG, or EMSG switches. The 1/2" port and M20x1.5 rod thread handle high flow. Viton H seals can raise the operating temperature to 150 C.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 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 SAUD100X400S Is Used
Twin-Spindle Machining
Drives two opposing machining heads with equal force in both directions, keeping the tooling synchronized without twist.
Dual Transfer Pusher
Pushes parts on one stroke while retracting the back rod to trip a limit switch, sequencing the conveyor line.
Vertical Lift Fixture
Lifts heavy pallets using the equal bidirectional force, carrying the load safely on the way up and down.
Is the Airtac SAUD Double Rod Cylinder SAUD100X400S the Right Cylinder?
Select this 100 mm bore if your task demands 3681 N both ways. Sizing down, the 80 mm bore provides 2268 N both ways at 0.5 MPa. Sizing up is not possible as 100 mm is the largest SAUD bore. Choose a double-rod design for anti-rotation guidance, driving twin tooling, or mounting a sensor cam on the back rod. Mounting is limited to Basic, FA, and LB types, matching the AirTAC SC series. The -S magnet allows electronic or reed sensing. Because the stroke is 400 mm, add external guides to prevent rod bending under side loads.
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 SAUD100X400S FAQ
The force is equal both ways because it is a double-rod design. It outputs 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa. The 1/2" port supplies the air needed for this 100 mm bore.
No. The air cushions only decelerate the piston near the stroke end; 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.
