Airtac SAUD Double Rod Cylinder SAUD50X40S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD50X40S is a genuine double-acting profile-type standard air cylinder with a Ø50mm bore and 40mm 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 SAUD50X40S
The AirTAC SAUD50X40S is a double-acting, double-rod profile cylinder featuring a 50 mm bore and a 40 mm stroke. Because a rod exits both ends, the push and pull forces are identical, delivering 825 N each way at 0.5 MPa. The extruded aluminum profile barrel makes it shorter than a standard ISO 15552 unit of the same size. This -S model includes a piston magnet for position sensing.
With a 1/4" port and M16x1.5 rod thread, this unit provides a 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 excellent anti-rotation stability, while the back rod can carry a switch cam. A Viton H seal option extends operating temperatures up to 150 C.

Where the Airtac SAUD Double Rod Cylinder SAUD50X40S Is Used
Twin-Tool Transfer
Drives two opposing tooling heads simultaneously from a single piston, ensuring perfectly matched timing and equal clamping pressure on both sides.
Balanced Lift Station
Lifts delicate electronics trays with equal force on the upstroke and downstroke, preventing sudden drops or acceleration spikes during transfer.
Cam-Triggered Sorting
Uses the protruding back rod to physically trip an external mechanical switch, providing a hard-wired confirmation independent of the main pneumatic system.
Is the Airtac SAUD Double Rod Cylinder SAUD50X40S the Right Cylinder?
Choose this 50 mm bore (825 N both ways at 0.5 MPa) if you need synchronized motion or anti-twist guidance. Step down to the 40 mm bore for 528 N, or up to the 63 mm bore for 1402 N if your application requires more thrust. Mounting is limited to Basic, FA, and LB styles compatible with the AirTAC SC series. At a 40 mm stroke, side-load risks are minimal, but always guide external loads to prevent binding. The -S suffix enables CMSG, DMSG, or EMSG 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 SAUD50X40S FAQ
The force is equal in both directions because it is a double-rod design. It outputs 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and 1484 N at 0.9 MPa. The 1/4" port supplies air to both chambers equally.
No, a plain double-rod cylinder drifts without live air; the adjustable 21 mm cushions only decelerate near the stroke ends. For secure load holding, install an external rod lock or a pilot-operated check valve.
