Airtac SAUD Double Rod Cylinder SAUD40X65
The AirTAC Airtac SAUD Double Rod Cylinder SAUD40X65 is a genuine double-acting profile-type standard air cylinder with a Ø40mm bore and 65mm 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 SAUD40X65
The AirTAC SAUD40X65 is a double-acting, double-rod profile cylinder with a 40 mm bore and 65 mm stroke. A rod exits both ends, meaning both faces use the rod-side area. This yields equal push and pull force of 528 N each way at 0.5 MPa. The extruded aluminium barrel keeps the unit shorter than an ISO 15552 cylinder of the same bore.
This SKU has no magnet, so it cannot take a magnetic switch. Based on the 528 N output, the safe working load is about 317 N, and it can vertically lift around 27 kg with a 2:1 margin. The 1/4" port and M12x1.25 rod thread match the 40 mm bore standard. A Viton H seal option raises the operating ceiling from 70 C to 150 C.

Where the Airtac SAUD Double Rod Cylinder SAUD40X65 Is Used
Twin Tool Transfer
Drives two opposing pickers simultaneously so both parts move in perfect sync without twisting.
Anti-Rotation Clamp
Clamps a workpiece from both sides with 528 N of equal force, preventing rotational drift.
Dual End Forming
Forms sheet metal flanges at both ends in one stroke using the twin rod outputs.
Is the Airtac SAUD Double Rod Cylinder SAUD40X65 the Right Cylinder?
Select this 40 mm bore if you need 528 N of equal force in both directions over a 65 mm stroke. Step down to the 32 mm bore for 345 N, or up to the 50 mm bore for 825 N. A double rod is the right call for anti-rotation guidance, driving twin tooling, or carrying a cam on the back rod. Mounting is limited to Basic, FA flange, and LB foot, matching the AirTAC SC series. At 65 mm stroke, side loads are minimal, but always guide the load externally for longer travels.
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 SAUD40X65 FAQ
The force is equal both ways because a rod exits both ends. It provides 528 N at 0.5 MPa, 739 N at 0.7 MPa, and 950 N at 0.9 MPa. Never expect a larger single-rod push value from this unit.
No. This specific SKU lacks the internal magnet, so it cannot trigger CMSG, DMSG, or EMSG switches. You would need the -S variant for position sensing. Also, the air cushion only decelerates the piston; use an external rod lock or pilot-operated check valve to hold a load.
