Airtac SAUD Double Rod Cylinder SAUD80X140
The AirTAC SAUD Double Rod Cylinder SAUD80X140 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 140mm stroke, 3/8" 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 SAUD80X140
The AirTAC SAUD80X140 is a double-acting, double-rod profile cylinder with an 80 mm bore and 140 mm stroke. A 25 mm rod exits both ends, meaning push and pull forces are identical at 2268 N each way at 0.5 MPa. The extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore. It features a 3/8" port, M20x1.5 rod thread, and 28 mm adjustable air cushions at both ends.
This SKU has no magnet (-S omitted), so it cannot take CMSG/DMSG/EMSG sensors. Because both faces lose rod area, output is equal both ways. A Viton H seal option raises the operating ceiling to 150 C.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAUD Double Rod Cylinder SAUD80X140 Is Used
Twin-Tool Machining
Drives two opposing machining heads simultaneously with identical 2268 N force, keeping cycle times balanced without needing two separate cylinders.
Synchronized Transfer
Shifts parallel conveyor lanes using both rod ends to push and pull a transfer carriage, ensuring the load stays square during transit.
Anti-Twist Lift
Raises and lowers heavy jigs with equal push and pull force, using the dual rods to resist torsional twisting that would jam a single-rod unit.
Is the Airtac SAUD Double Rod Cylinder SAUD80X140 the Right Cylinder?
Choose this 80 mm bore (2268 N both ways at 0.5 MPa) if you need high equal force for anti-rotation or twin-tool tasks. Step down to the 63 mm bore (1402 N) for lighter loads, or up to the 100 mm bore (3681 N) for heavier duty. Mounting is limited to Basic, FA, and LB types compatible with the AirTAC SC series. Since this non-magnetic SKU cannot carry a switch, add the -S suffix if you need back-end sensing. At 140 mm stroke side loads are minimal, but for any stroke over 300 mm use external guides to prevent rod 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 SAUD80X140 FAQ
Because the 25 mm rod exits both ends, force is equal in both directions. It outputs 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa.
No. The 28 mm adjustable cushions only decelerate the piston near stroke end; they do not lock. For load holding on air loss, fit an external rod lock or pilot-operated check valve.
