Airtac SAUD Double Rod Cylinder SAUD50X225
The AirTAC Airtac SAUD Double Rod Cylinder SAUD50X225 is a genuine double-acting profile-type standard air cylinder with a Ø50mm bore and 225mm stroke, 1/4" 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 SAUD50X225
The AirTAC SAUD50X225 is a double-acting, double-rod profile cylinder. A 20mm rod protrudes from both ends of the hard-anodized aluminum barrel, meaning both faces use the rod-side area. This yields an equal output force of 825 N in both directions at 0.5 MPa. The extruded profile body is noticeably shorter than a standard ISO 15552 unit of the same bore.
Because both ends carry a rod, the unit provides inherent anti-rotation guidance and can drive two tools simultaneously. The 1/4" port and M16x1.5 rod thread match the bore standard. This specific SKU lacks a magnet, so it cannot accept CMSG or DMSG switches. For sizing, the 825 N output at 0.5 MPa translates to a safe working load of roughly 495 N, or a vertical lift capacity of about 42 kg with a 2:1 safety margin.

Where the Airtac SAUD Double Rod Cylinder SAUD50X225 Is Used
Twin-Tool Transfer
Drives two opposing grippers simultaneously to pick and place parts from parallel conveyors with perfectly matched timing.
Anti-Rotation Lift
Raises and lowers a 42kg machining fixture smoothly without twisting, relying on the dual rods for inherent guidance.
Cam-Actuated Clamping
Uses the extended rear rod to mechanically trip a limit valve at mid-stroke while the front rod secures the workpiece.
Is the Airtac SAUD Double Rod Cylinder SAUD50X225 the Right Cylinder?
When sizing this 50mm bore, stepping down to a 40mm bore gives 528 N both ways, while stepping up to a 63mm bore provides 1402 N. Choose this double-rod configuration when your mechanism requires strict anti-twist stability, synchronized twin-tool driving, or a rear rod to act as a mechanical cam. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. Since this SKU has no internal magnet, you cannot mount proximity sensors. At a 225mm stroke, side-load stress is moderate, but always use external guide rails to prevent binding. Note that air cushions only decelerate the piston near the end of travel; they do not hold the load. To prevent drift 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 SAUD50X225 FAQ
The force is equal in both directions because the 20mm rod exits both ends. It generates 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and 1484 N at 0.9 MPa.
No. This specific SKU is built without a magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S version for electronic position sensing.
