Airtac SAUD Double Rod Cylinder SAUD40X80
The AirTAC Airtac SAUD Double Rod Cylinder SAUD40X80 is a genuine double-acting profile-type standard air cylinder with a Ø40mm bore and 80mm 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 SAUD40X80
The AirTAC SAUD40X80 is a double-acting, double-rod profile cylinder with a 40 mm bore and an 80 mm stroke. A 16 mm rod exits both ends, meaning both faces use the rod-side area. Output is equal in both directions, delivering 528 N each way at 0.5 MPa. The extruded hard-anodized aluminum barrel keeps the unit shorter than an ISO 15552 cylinder of the same bore.
With a 528 N equal force, the safe working load is roughly 317 N, and it can vertically lift about 27 kg with a 2:1 safety margin. This SKU has no magnet (-S), so it cannot take a magnetic switch. The 1/4" port and M12x1.25 rod thread are fixed by the bore. For high-heat duties up to 150 C, specify the Viton H seal option.

Where the Airtac SAUD Double Rod Cylinder SAUD40X80 Is Used
Twin-Tool Transfer
Drives two parallel pickers simultaneously from one piston, keeping stroke perfectly synchronized for part handoff between conveyors.
Balanced Vertical Lift
Equal push and pull force prevents sagging drift when raising and lowering a 27 kg fixture, ensuring smooth vertical travel both ways.
Anti-Rotation Clamp
Dual rods resist torsional twist during gripping, holding a workpiece steady without needing external linear bearings.
Is the Airtac SAUD Double Rod Cylinder SAUD40X80 the Right Cylinder?
Choose this 40 mm bore (528 N both ways at 0.5 MPa) if your application needs synchronized motion or anti-twist guidance. Step down to the 32 mm bore for 345 N, or up to the 50 mm bore for 825 N. A double rod is ideal for driving twin tooling or mounting a cam on the back rod. Mounting is limited to Basic, FA flange, and LB foot, matching the AirTAC SC series. At 80 mm stroke, side loads are minimal, but always guide the load externally for longer strokes. This non-magnetic SKU cannot host CMSG or DMSG sensors.
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 SAUD40X80 FAQ
Because the 16 mm rod exits both ends, force is equal both ways: 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. A plain double-rod cylinder drifts without live air; the adjustable 21 mm cushions only decelerate near stroke end. For load holding, add an external rod lock or pilot-operated check valve.
