Airtac SAUD Double Rod Cylinder SAUD40X95S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD40X95S is a genuine double-acting profile-type standard air cylinder with a Ø40mm bore and 95mm 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 SAUD40X95S
The AirTAC SAUD40X95S is a double-acting, double-rod profile cylinder. A 16mm rod exits both ends, meaning push and pull forces are identical at 528 N each way at 0.5 MPa. The extruded aluminium barrel is shorter than an ISO 15552 cylinder of the same 40mm bore. It features a 1/4" port and M12x1.25 rod threads.
With the -S suffix, this unit includes a piston magnet for CMSG, DMSG or EMSG switches. The rear rod can carry a sensor cam or trip a switch. For sizing, a safe working load is roughly 317 N, and a vertical lift capacity is about 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 SAUD40X95S Is Used
Vertical Lift Stations
Lifts small platens with 27 kg vertical lift capacity, using the equal force to raise and lower tooling smoothly without drift bias.
Twin-Tool Transfer
Drives two separate pickers simultaneously from one piston, using both protruding rod ends to carry identical end-effectors.
Rear-Cam Sensing
Uses the back rod to trip an external limit switch or carry a DMSG sensor cam, freeing the primary rod face for the main work tool.
Is the Airtac SAUD Double Rod Cylinder SAUD40X95S the Right Cylinder?
Choose this 40mm bore when you need 528 N of equal force in both directions. Step down to the 32mm bore for 345 N, or up to the 50mm bore for 825 N. The double-rod design suits anti-rotation, twin-tooling, and back-end sensing tasks. Mounting is limited to Basic, FA, and LB styles, matching the AirTAC SC series. At a 95mm stroke, side loads are minimal, but external guides are recommended for longer strokes. The -S magnet enables electronic 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 SAUD40X95S FAQ
The force is equal in both directions because both faces use the rod-side area. It outputs 528 N at 0.5 MPa, 739 N at 0.7 MPa, and 950 N at 0.9 MPa. The air port is 1/4".
No, a plain cylinder drifts without live air; the adjustable cushion only decelerates near stroke end. Use an external rod lock or pilot-operated check valve to hold a load.
