Airtac SAUD Double Rod Cylinder SAUD40X50S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD40X50S is a genuine double-acting profile-type standard air cylinder with a Ø40mm bore and 50mm 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 SAUD40X50S
The AirTAC SAUD40X50S is a double-acting profile-type cylinder with a 16 mm rod exiting both ends, yielding identical push and pull thrust of 528 N each way at 0.5 MPa. The extruded aluminum barrel keeps the unit shorter than an ISO 15552 cylinder of the same bore. A 1/4 inch port supplies air, while the -S suffix indicates a built-in piston magnet for CMSG, DMSG, or EMSG switches.
Because both faces use the rod-side area, the output is equal both ways, making it ideal for non-rotating or twin-tool tasks. The safe working load is about 317 N, which translates to a vertical lift capacity of roughly 27 kg with a 2:1 margin. You can also mount a switch cam on the back rod. For high-temperature environments up to 150 C, specify the Viton H seal option.

Where the Airtac SAUD Double Rod Cylinder SAUD40X50S Is Used
Twin-Tool Transfer
Drives two opposing grippers simultaneously with equal 528 N force, ensuring perfectly synchronized part handoff between conveyor stations.
Anti-Rotation Lift
Lifts delicate electronics trays straight up without twist, using the dual rods to maintain strict angular stability throughout the 50 mm travel.
Cam-Trip Sensing
Uses the protruding back rod to physically trigger an external limit valve, while the internal -S magnet operates CMSG reed switches for dual confirmation.
Is the Airtac SAUD Double Rod Cylinder SAUD40X50S the Right Cylinder?
Choose this 40 mm bore if you need 528 N of equal bidirectional force at 0.5 MPa. Stepping up to the 50 mm bore provides 825 N, while dropping to the 32 mm bore offers 345 N. A double-rod design is the right call when your application demands anti-rotation guidance, synchronized twin tooling, or back-end switch tripping. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. The -S magnet enables electronic or reed sensing. Since the stroke is 50 mm, side-load risks are minimal, but always guide external loads to prevent binding.
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 SAUD40X50S FAQ
The force is equal both ways because a 16 mm rod exits both ends. It generates 528 N at 0.5 MPa, 739 N at 0.7 MPa, and 950 N at 0.9 MPa. The 1/4 inch port supplies air to both chambers.
No, the air cushion only decelerates the piston near the stroke end and does not lock the load. If pressure is lost, the piston will drift. Use an external rod lock or pilot-operated check valve for secure load holding.
