Airtac SAUD Double Rod Cylinder SAUD50X240
The AirTAC Airtac SAUD Double Rod Cylinder SAUD50X240 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 SAUD50X240
The AirTAC SAUD50X240 is a double-acting, double-rod profile cylinder. A 20 mm rod exits both ends, meaning push and pull output are identical at 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 50 mm bore. It operates at 30-800 mm/s and uses a 1/4" port.
This configuration delivers a safe working load of roughly 495 N, or a vertical lift capacity of about 42 kg with a 2:1 margin. You can specify Viton H seals to raise the operating temperature limit to 150 C. Because this specific SKU lacks the -S magnet option, it cannot accept CMSG, DMSG, or EMSG magnetic switches.

Where the Airtac SAUD Double Rod Cylinder SAUD50X240 Is Used
Twin-Tool Stamping
Drives two synchronized forming tools from opposite rod ends, ensuring parallel contact and equal 825 N thrust throughout the cycle.
Anti-Rotation Diverter
Uses the dual-rod structure to prevent mechanical twist while pushing packages across a belt, maintaining precise alignment without external guides.
Balanced Vertical Lift
Lifts up to 42 kg with a 2:1 safety factor, where the matched push and pull forces provide smooth descent and stable stopping via the 21 mm cushions.
Is the Airtac SAUD Double Rod Cylinder SAUD50X240 the Right Cylinder?
Choose this 50 mm bore when a task needs equal push and pull thrust, such as anti-rotation guidance or driving twin tooling. Stepping down, the 40 mm bore yields 528 N each way, while stepping up to the 63 mm bore provides 1402 N. Mounting is limited to Basic, FA flange, or LB foot styles that match the AirTAC SC series. With a 240 mm stroke, external side-load guides are recommended to prevent rod binding. Note that a plain cylinder drifts on air loss; the cushions only decelerate near the end caps, so add an external rod lock for held loads.
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 SAUD50X240 FAQ
The double-rod design provides 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 produces a larger single-rod push value.
No. This specific SKU does not include the -S magnet, so it cannot operate CMSG, DMSG, or EMSG switches. You would need the -S variant for electronic position sensing.
