Airtac SAUD Double Rod Cylinder SAUD50X290
The AirTAC Airtac SAUD Double Rod Cylinder SAUD50X290 is a genuine double-acting profile-type standard air cylinder with a Ø50mm bore and 290mm 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 SAUD50X290
The AirTAC SAUD50X290 is a double-acting double-rod profile cylinder with a 50mm bore and 290mm stroke. A rod protrudes from both ends, meaning the push and pull forces are identical at 825 N each way at 0.5 MPa. The extruded aluminium barrel makes it shorter than an ISO 15552 cylinder of the same bore.
This unit has a 1/4" port and lacks the -S magnet, so it cannot accept magnetic switches. The twin rods provide anti-rotation guidance and let you drive two tools at once. Based on the 825 N figure, the safe working load is about 495 N, yielding a vertical lift capacity of roughly 42 kg with a 2:1 margin.

Where the Airtac SAUD Double Rod Cylinder SAUD50X290 Is Used
Twin-Spindle Lifting
Drives two parallel work heads simultaneously with equal force, keeping synchronized vertical lifting perfectly balanced without twist.
Dual Transfer Arms
Powers opposing transfer fingers at both rod ends to push and pull packages across a belt in alternating directions with identical strength.
Guided Vertical Stopper
Acts as a heavy-duty stop gate where the second rod prevents rotation, ensuring the barrier face remains square under side impact.
Is the Airtac SAUD Double Rod Cylinder SAUD50X290 the Right Cylinder?
This 50mm bore delivers 825 N both ways; step down to the 40mm bore for 528 N, or up to the 63mm bore for 1402 N. Choose a double-rod design when you need strict anti-twist guidance or twin tool mounting. It uses AirTAC SC series FA flange or LB foot mounts. As the 290mm stroke exceeds 300mm thresholds, ensure external side-load guides support the rod to prevent binding. Because this SKU lacks the -S magnet, it cannot host sensors.
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 SAUD50X290 FAQ
Because it is a double-rod cylinder, the 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. It uses a 1/4" port.
No. The air cushions only decelerate the piston near the stroke ends; they do not lock the load. For vertical load holding, you must add an external rod lock or a pilot-operated check valve.
