Airtac SAUD Double Rod Cylinder SAUD50X240S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD50X240S is a genuine double-acting profile-type standard air cylinder with a Ø50mm bore and 240mm 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 SAUD50X240S
The AirTAC SAUD50X240S is a double-acting, double-rod profile cylinder. A 20 mm rod protrudes from both ends, meaning push and pull forces are identical at 825 N each way at 0.5 MPa. The extruded aluminum barrel keeps the unit shorter than an ISO 15552 cylinder of the same bore.
This -S variant includes a piston magnet for CMSG, DMSG, or EMSG switches. The 1/4" port and M16x1.5 rod thread are standard. Based on the 825 N output, the safe working load is about 495 N, allowing a vertical lift of roughly 42 kg with a 2:1 safety margin. A Viton H seal option extends operation to 150 C.

Where the Airtac SAUD Double Rod Cylinder SAUD50X240S Is Used
Twin-Tool Stamping
Drives two synchronized forming tools from one piston, ensuring parallel contact without rotational twist.
Dual Transfer Pusher
Uses both rod ends to push alternating pallets on parallel conveyors, halving cycle time.
Cam-Trip Limiting
Mounts a switch cam on the rear rod to trip external proximity sensors in tight spaces.
Is the Airtac SAUD Double Rod Cylinder SAUD50X240S the Right Cylinder?
Choose this 50 mm bore if you need 825 N of equal force in both directions. Step down to the 40 mm bore for 528 N, or up to the 63 mm bore for 1402 N. A double rod is ideal for anti-rotation guidance, driving twin tooling, or mounting a switch cam on the back. Mounting is limited to Basic, FA flange, and LB foot styles compatible with the AirTAC SC series. At 240 mm stroke, external side-load guides are recommended. The -S magnet enables position sensing.

- ✓ 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 SAUD50X240S FAQ
Because the 20 mm rod exits both ends, 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. The 1/4" port supplies air to both chambers.
No, the piston drifts without live air. The adjustable cushions only decelerate near stroke end. For load holding, install an external rod lock or pilot-operated check valve.
