Airtac SAUD Double Rod Cylinder SAUD50X300
The AirTAC Airtac SAUD Double Rod Cylinder SAUD50X300 is a genuine double-acting profile-type standard air cylinder with a Ø50mm bore and 300mm 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 SAUD50X300
The AirTAC SAUD50X300 is a double-acting, double-rod profile cylinder. A rod protrudes from both ends, meaning the push and pull forces are equal at 825 N each way at 0.5 MPa. The extruded hard-anodized aluminum barrel keeps the unit shorter than a standard ISO 15552 cylinder of the same bore. It features a 1/4" port and M16x1.5 rod thread.
This 50 mm bore model delivers a computed safe working load of roughly 495 N (about 60% of the 0.5 MPa force) and can vertically lift approximately 42 kg with a 2:1 safety margin. The twin-rod geometry provides inherent anti-rotation guidance, and the back rod can drive dual tools. A high-temperature Viton H seal option extends operation from 0 to 150 C.

Where the Airtac SAUD Double Rod Cylinder SAUD50X300 Is Used
Twin-Tool Transfer
Drives two independent workpieces simultaneously from opposite rod ends, keeping cycle times synchronized without adding a second cylinder.
Anti-Rotation Gripper
Uses the dual-rod structure to prevent mechanical twist during part clamping, ensuring precise jaw alignment on machined components.
Dual-End Pressing
Applies equal 825 N pressing force on both the forward and return strokes to seat bearings or pins in automated assembly jigs.
Is the Airtac SAUD Double Rod Cylinder SAUD50X300 the Right Cylinder?
Choose this 50 mm bore (825 N both ways) if you need synchronized motion or non-rotating anti-twist guidance. Step down to the 40 mm bore for 528 N, or up to the 63 mm bore for 1402 N. Mounting is limited to Basic, FA flange, and LB foot styles matching the AirTAC SC series. Because this is a 300 mm stroke, external guides are recommended to prevent rod bending under side loads. Note this SKU lacks the -S magnet, so it cannot accept CMSG or DMSG 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 SAUD50X300 FAQ
The double-rod design yields equal force in both directions: 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and 1484 N at 0.9 MPa. It never outputs a larger single-rod push value.
No. A plain SAUD cylinder drifts on air loss or when the valve is centered; the adjustable air cushion only decelerates near stroke end. For load holding, install an external rod lock or pilot-operated check valve.
