Airtac SAUD Double Rod Cylinder SAUD50X190S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD50X190S is a genuine double-acting profile-type standard air cylinder with a Ø50mm bore and 190mm 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 SAUD50X190S
The AirTAC SAUD50X190S is a double-acting, double-rod profile cylinder featuring a 50 mm bore and a 190 mm stroke. Because a rod protrudes from both ends, the push and pull forces are identical, yielding 825 N each way at 0.5 MPa. The extruded hard-anodized aluminum barrel keeps the unit 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, this unit delivers a computed safe working load of roughly 495 N. For vertical lifting tasks, it can handle approximately 42 kg with a 2:1 safety margin. The back rod is perfect for carrying a sensor cam, and Viton H seals can raise the operating temperature limit to 150 C.

Where the Airtac SAUD Double Rod Cylinder SAUD50X190S Is Used
Twin-Tool Transfer
Drives two opposing grippers simultaneously with equal push and pull force, ensuring perfectly synchronized part handoff between stations.
Balanced Vertical Lift
Lifts payloads up to 42 kg vertically with a 2:1 margin, using the equal bidirectional force to maintain smooth descent without drift imbalance.
Cam-Triggered Sorting
Uses the extended back rod to trip an external mechanical switch, confirming full extension independently of the onboard magnetic sensors.
Is the Airtac SAUD Double Rod Cylinder SAUD50X190S the Right Cylinder?
Choose this 50 mm bore (825 N equal force) if your application requires anti-rotation guidance or twin tooling. Sizing up to the 63 mm bore provides 1402 N, while stepping down to the 40 mm bore offers 528 N. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. At a 190 mm stroke, side loads are moderate, but always use external guide rails to prevent binding. The -S magnet supports CMSG, DMSG, and EMSG switches.

- ✓ 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 SAUD50X190S 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. The 1/4" port ensures reliable airflow for these ratings.
No, a plain double-rod cylinder will drift without live air, as the adjustable cushions only decelerate the piston near stroke end. For secure load holding, install an external rod lock or a pilot-operated check valve.
