Airtac SAUD Double Rod Cylinder SAUD100X145
The AirTAC SAUD Double Rod Cylinder SAUD100X145 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 145mm 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 SAUD100X145
The AirTAC SAUD100X145 is a double-acting, double-rod profile cylinder. A 25mm rod exits both ends of the hard-anodized aluminum barrel, meaning push and pull forces are identical at 3681 N each way at 0.5 MPa. This extruded profile body is significantly shorter than a standard ISO 15552 unit of the same 100mm bore. It features a 1/2 inch port, M20x1.5 rod threads, and 29mm adjustable air cushions at each end.
Because the piston travels only 145mm, side-loading is minimal, but external guides are always recommended for precise tracking. The twin-rod geometry provides excellent anti-rotation resistance and lets you mount twin tooling or a switch cam on the back rod. Note this SKU lacks a magnet, so it cannot accept CMSG or DMSG sensors.

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 SAUD100X145 Is Used
Twin-Spindle Drilling
Drives two synchronized machining spindles from one piston, utilizing the equal force and rigid anti-twist properties of the dual rods.
Dual Pneumatic Diverter
Mounts opposing guide arms on both rod ends to sort or lane heavy packages simultaneously from a central profile body.
Balanced Heavy Press
Applies a steady 3681 N clamping force on the downstroke and matches it exactly on the retraction for balanced press ejection.
Is the Airtac SAUD Double Rod Cylinder SAUD100X145 the Right Cylinder?
Choose this 100mm bore if your application demands high equal-force bidirectional thrust. Sizing up or down: the neighboring 80mm bore yields 2268 N each way at 0.5 MPa, while no larger standard bore exists in this series. A double-rod design is the right call when you need strict anti-rotation guidance, synchronized twin tooling, or a back-end sensor cam. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. Because this specific SKU has no internal magnet (-S), you cannot mount magnetic sensors; if you need position detection, select a -S variant. For any stroke at or over 300mm, always use external guide rails to prevent rod binding.
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 SAUD100X145 FAQ
The force is equal in both directions because of the 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 inch port and 25mm rods ensure consistent thrust on both extend and retract strokes.
No, a plain double-rod cylinder will drift without live air. The 29mm cushions only decelerate the piston near the stroke ends; they do not lock the load. To hold a vertical load safely, install an external rod lock or a pilot-operated check valve.
