Airtac SAUD Double Rod Cylinder SAUD40X5S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD40X5S is a genuine double-acting profile-type standard air cylinder with a Ø40mm bore and 5mm 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 SAUD40X5S
The AirTAC SAUD40X5S is a double-acting, double-rod profile cylinder with a 40mm bore and 5mm stroke. A rod exits both ends, meaning push and pull forces are identical at 528 N each way at 0.5 MPa. The extruded aluminum barrel makes it shorter than an ISO 15552 unit of the same bore. It features a 1/4 inch port and M12x1.25 rod thread.
This -S variant includes a piston magnet for CMSG, DMSG, or EMSG switches. The equal force suits twin-tool or anti-rotation tasks. Based on the 528 N output, the safe working load is about 317 N, allowing a vertical lift of roughly 27 kg with a 2:1 margin. A Viton H seal option raises the operating temperature to 150 C.

Where the Airtac SAUD Double Rod Cylinder SAUD40X5S Is Used
Synchronized Gripper Jaws
Drives opposing gripper fingers with identical force and stable anti-rotation mechanics for precision part handling.
Twin-Tool Stamping
Powers two small marking pins simultaneously from a single compact body, ensuring balanced impact at both ends.
Back-End Switch Cam
Uses the protruding rear rod to trip an external limit switch, providing a physical confirmation signal.
Is the Airtac SAUD Double Rod Cylinder SAUD40X5S the Right Cylinder?
Choose this 40mm bore if you need 528 N of equal force in both directions. Sizing down, the 32mm bore yields 345 N each way. Sizing up, the 50mm bore provides 825 N. A double rod is ideal for anti-rotation guidance, driving two tools, or mounting a sensor cam on the back. Mounting fits AirTAC SC series FA flange and LB foot brackets. The built-in magnet supports reed and electronic sensing. For any stroke over 300mm, use external guide rails to prevent side-load wear.
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 SAUD40X5S FAQ
The force is equal in both directions because it is a double-rod design. It provides 528 N at 0.5 MPa, 739 N at 0.7 MPa, and 950 N at 0.9 MPa.
No, the air cushion only decelerates the piston near the stroke end. To hold a load securely, you must add an external rod lock or a pilot-operated check valve.
