Airtac SAUD Double Rod Cylinder SAUD50X20
The AirTAC Airtac SAUD Double Rod Cylinder SAUD50X20 is a genuine double-acting profile-type standard air cylinder with a Ø50mm bore and 20mm 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 SAUD50X20
The AirTAC SAUD50X20 is a double-acting double-rod profile cylinder featuring a 50mm bore and 20mm stroke. A rod exits both ends, meaning both faces use the rod-side piston area to deliver an equal 825 N of thrust and pull at 0.5 MPa. The extruded aluminium barrel keeps the unit shorter than a standard ISO 15552 cylinder of the same bore.
This twin-rod layout provides excellent anti-rotation guidance and lets you drive two tools at once. Without the -S suffix, this specific SKU lacks a magnet and cannot host CMSG or DMSG sensors. Based on the 825 N output, your safe working load is roughly 495 N, which translates to a vertical lift capacity of about 42 kg with a 2:1 safety margin.

Where the Airtac SAUD Double Rod Cylinder SAUD50X20 Is Used
Twin-Tool Transfer
Drives two synchronized pick-and-place heads from opposite rod ends, ensuring perfectly balanced, non-rotating horizontal transfer.
Symmetric Clamping
Applies equal 825 N clamping pressure from both faces simultaneously, ideal for centering and holding delicate workpieces.
Short Lift Stations
Handles compact 20mm vertical lifting tasks up to 42kg with a 2:1 margin, using the back rod as a mechanical stop.
Is the Airtac SAUD Double Rod Cylinder SAUD50X20 the Right Cylinder?
Select this 50mm bore model when your application demands equal force both ways, needing 825 N at 0.5 MPa. If you need less thrust, the 40mm bore offers 528 N both ways; for heavier duty, the 63mm bore provides 1402 N. The 1/4 inch port suits typical flow rates. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. Because this is a non-magnet SKU, you cannot fit position sensors. For any stroke over 300mm, always use external guides to prevent side-load wear.
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 SAUD50X20 FAQ
Because the double rod occupies area on both faces, force is equal in both directions: 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and 1484 N at 0.9 MPa. The 1/4 inch port supplies air to both chambers.
No. The adjustable air cushion only decelerates the piston near the stroke end; it does not lock the load. If air is lost, the piston drifts. For vertical load holding, install an external rod lock or a pilot-operated check valve.
