Airtac SAUD Double Rod Cylinder SAUD80X155
The AirTAC SAUD Double Rod Cylinder SAUD80X155 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 155mm 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 SAUD80X155
The AirTAC SAUD80X155 is a double-acting, double-rod profile cylinder featuring an 80mm bore and 155mm stroke. Because a rod exits both ends, the push and pull forces are identical, delivering 2268 N each way at 0.5 MPa. The extruded aluminum barrel keeps the unit shorter than an ISO 15552 cylinder of the same bore.
This configuration uses a 3/8" port and a 25mm piston rod with an M20x1.5 thread. Without the -S magnet option, this specific SKU cannot accept magnetic sensors.

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 SAUD80X155 Is Used
Dual-Tool Transfer
Drives two synchronized workpieces simultaneously from opposite rod ends on a packaging line.
Anti-Twist Clamping
Applies 2268 N of equal clamping force without piston rotation during precision machining tasks.
Balanced Lowering
Lowers heavy 116 kg assemblies smoothly using twin rods to prevent binding in vertical presses.
Is the Airtac SAUD Double Rod Cylinder SAUD80X155 the Right Cylinder?
When sizing this 80mm bore, note the 2268 N equal force both ways. If you need less power, the 63mm bore provides 1402 N both ways; if you need more, the 100mm bore offers 3681 N. Choose this double-rod model when your application demands anti-rotation guidance, twin tooling, or a back-end cam. Mounting is limited to Basic, FA, and LB styles compatible with the AirTAC SC series. At a 155mm stroke, side loads are minimal, but always use external guides for longer strokes. Remember that a plain cylinder drifts without air; use an external rod lock for load holding.
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 SAUD80X155 FAQ
The force is equal in both directions due to the double-rod design. It outputs 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa.
No, this SKU lacks the internal magnet. You must select a -S designated model to use CMSG, DMSG, or EMSG magnetic switches along the profile barrel.
