Airtac SAUD Double Rod Cylinder SAUD50X65S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD50X65S is a genuine double-acting profile-type standard air cylinder with a Ø50mm bore and 65mm 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 SAUD50X65S
The AirTAC SAUD50X65S is a double-acting, double-rod profile cylinder with a 50 mm bore and 65 mm stroke. Because a rod exits both ends, the push and pull forces are equal at 825 N each way at 0.5 MPa. The extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore. This -S variant includes a piston magnet for position sensing.
With a 1/4" port and M16x1.5 rod thread, it delivers a safe working load of roughly 495 N (about 60% of the 0.5 MPa force). This translates to a vertical lift capacity of approximately 42 kg with a 2:1 safety margin. The back rod can carry a sensor cam or drive a second tool simultaneously. A Viton H seal option raises the operating temperature to 0-150 C.

Where the Airtac SAUD Double Rod Cylinder SAUD50X65S Is Used
Twin-Tool Transfer
Drives two opposing grippers simultaneously to pick and place parts from both sides of a workstation without twisting.
Cam-Triggered Sorting
Uses the extended back rod to physically trip a limit switch or carry a sensor cam for precise end-of-stroke confirmation.
Balanced Lift Station
Raises and lowers a 42 kg vertical load with equal force in both directions, preventing sagging during return strokes.
Is the Airtac SAUD Double Rod Cylinder SAUD50X65S the Right Cylinder?
Choose this 50 mm bore (825 N both ways at 0.5 MPa) if you need anti-rotation guidance or twin-tool actuation. Step down to a 40 mm bore for 528 N, or up to a 63 mm bore for 1402 N. Mounting is limited to Basic, FA, and LB styles matching the AirTAC SC series. The -S magnet supports CMSG, DMSG, and EMSG switches. For this 65 mm stroke, side loads are minimal, but always use external guides for longer strokes over 300 mm.
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 SAUD50X65S FAQ
The force is equal in both directions due to the double-rod design. It outputs 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, a plain cylinder drifts without live air. The adjustable air cushion only decelerates near the stroke end. For load holding, install an external rod lock or pilot-operated check valve.
