Airtac SAUD Double Rod Cylinder SAUD40X175S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD40X175S is a genuine double-acting profile-type standard air cylinder with a Ø40mm bore and 175mm 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 SAUD40X175S
The AirTAC SAUD40X175S is a double-acting, double-rod profile cylinder with a 40 mm bore and 175 mm stroke. A rod extends from both ends, meaning push and pull forces are identical at 528 N each way at 0.5 MPa. The extruded aluminium barrel keeps the body shorter than a standard ISO 15552 unit of the same bore.
This -S variant includes a piston magnet for CMSG, DMSG or EMSG switches. It uses a 1/4 inch port and M12x1.25 rod thread. Based on the 528 N output, the safe working load is about 317 N, translating to a 27 kg vertical lift with a 2:1 safety margin. A Viton H seal option can raise the operating ceiling to 150 C.

Where the Airtac SAUD Double Rod Cylinder SAUD40X175S Is Used
Synchronized Transfer
Drives two pickup fingers simultaneously from opposite rod ends to transfer small electronic parts evenly.
Anti-Rotation Cutter
Holds a cutting blade rigidly on both faces to slice film without twist during the downward motion.
Cam Trip Sensing
Uses the protruding back rod as a cam to physically trigger an external limit switch at mid-stroke.
Is the Airtac SAUD Double Rod Cylinder SAUD40X175S the Right Cylinder?
Choose this 40 mm bore delivering 528 N equal force if your task needs anti-rotation guidance or twin tooling. Stepping down, the 32 mm bore yields 345 N both ways; stepping up, the 50 mm bore offers 825 N. Mounting uses SC-series FA flange or LB foot brackets. The built-in magnet allows direct switch mounting. With a 175 mm stroke, always use an external guide to prevent side-load 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 SAUD40X175S FAQ
Because it is a double-rod design, force is equal in both directions: 528 N at 0.5 MPa, 739 N at 0.7 MPa, and 950 N at 0.9 MPa. It uses a 1/4 inch port.
No, the piston drifts without live air. The adjustable cushions only decelerate near stroke ends. Use an external rod lock or pilot-operated check valve for secure load holding.
