Airtac SAUD Double Rod Cylinder SAUD100X450S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD100X450S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 450mm 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 SAUD100X450S
The AirTAC SAUD100X450S is a double-acting double-rod profile cylinder. A 25mm rod exits both ends of the 100mm bore, meaning the push and pull force is identical at 3681 N each way at 0.5 MPa. The extruded aluminum body is shorter than an equivalent standard bore, and this -S variant includes a magnet for CMSG, DMSG or EMSG switches.
With a 450mm stroke, external guides are recommended to prevent rod bending under side loads. The 1/2 inch port drives the piston at 30-800 mm/s.

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 SAUD100X450S Is Used
Twin-Tool Machining Station
Drives two opposing machining heads simultaneously with equal 3681 N force, ensuring perfectly balanced material removal on both sides of a heavy workpiece.
Synchronized Transfer Pusher
Uses both rod ends to push and retract a dual-belt conveyor alignment fence, maintaining parallel movement without rotational twist over the 450mm travel.
Pallet Load Rejecter
Ejects heavy non-conforming pallets from a high-speed line, using the back rod to trip an external mechanical flag while the front rod executes the 188 kg vertical lift.
Is the Airtac SAUD Double Rod Cylinder SAUD100X450S the Right Cylinder?
When sizing this double-rod unit, compare it against the 80mm bore (2268 N each way) and the 100mm bore (3681 N each way). Choose the 100mm when your application requires high equal forces for non-rotating anti-twist guidance, twin tooling setups, or mounting a sensor cam on the back rod. Mounting is limited to Basic, FA flange, and LB foot brackets compatible with the AirTAC SC series. Because the 450mm stroke is long, always use external linear guides to absorb side loads and prevent rod bending. Note that air cushions only decelerate the piston near the end of travel; to hold a load securely on air loss, install an external rod lock or pilot-operated check valve.
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 SAUD100X450S FAQ
Because the 25mm piston rod exits both ends, the force is equal in both directions: 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa. The 1/2 inch port and 29mm adjustable cushions handle the 30-800 mm/s speed range.
No. The adjustable air cushions only decelerate the piston near the stroke ends; they do not lock the position. If air is lost, the load will drift. Use an external rod lock or pilot-operated check valve for secure load holding.
