Airtac SAUD Double Rod Cylinder SAUD100X55S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD100X55S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 55mm 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 SAUD100X55S
The AirTAC SAUD100X55S is a double-acting profile-type cylinder with a rod protruding from both ends. Because both faces lose rod area, output is identical in extension and retraction, yielding 3681 N each way at 0.5 MPa. The extruded aluminum barrel keeps the body shorter than an ISO 15552 unit of the same bore, and the 1/2 inch port feeds the 100 mm piston efficiently.
This unit includes the -S magnet option for CMSG, DMSG, or EMSG switches. The rear rod is perfect for carrying a sensor cam or driving twin tools. A Viton H seal can raise the operating ceiling 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 SAUD100X55S Is Used
Twin-Spindle Machining
Drives two synchronized machining heads from one piston, ensuring perfectly balanced cutting feed without rotational twist.
Dual Pusher Array
Pushes parallel items on a conveyor simultaneously using fixtures attached to both rod ends for matched timing.
Lift and Transfer Gate
Raises and lowers a transfer gate with equal force both ways, using the rear rod to trigger a reed limit switch.
Is the Airtac SAUD Double Rod Cylinder SAUD100X55S the Right Cylinder?
Select this 100 mm bore if your task needs 3681 N of equal push and pull force. Stepping down, the 80 mm bore provides 2268 N, while the 100 mm is the largest standard size. A double rod is ideal when you need anti-rotation guidance, synchronized twin tooling, or back-end switch tripping. Mounting is limited to Basic, FA flange, and LB foot styles matching the AirTAC SC series. At 55 mm stroke, side loads are minimal, but always use external guides for longer travels. The -S suffix enables electronic position sensing.
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 SAUD100X55S FAQ
The force is equal both ways because it is a double-rod design. It provides 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa. The 1/2 inch port supplies the 100 mm bore.
No, the adjustable 29 mm cushions only decelerate the piston near the stroke ends. To prevent drift on air loss, install an external rod lock or pilot-operated check valve.
