Airtac SAUD Double Rod Cylinder SAUD80X145
The AirTAC SAUD Double Rod Cylinder SAUD80X145 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 145mm 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 SAUD80X145
The AirTAC SAUD80X145 is a double-acting, double-rod profile cylinder featuring an 80 mm bore and a 145 mm stroke. A Ø25 mm rod protrudes from both ends, meaning both faces use the identical rod-side area. This yields exactly 2268 N of output force at 0.5 MPa in both directions. The extruded hard-anodized aluminum barrel keeps the unit shorter than an ISO 15552 cylinder of the same bore. It connects via 3/8" ports and includes adjustable 28 mm air cushions at each end.
Because the piston rod exits both sides, this design provides inherent anti-rotation guidance and can drive two separate tools simultaneously. Without the -S suffix, this specific SKU lacks a magnet and cannot host CMSG or DMSG switches. A Viton H seal option can extend operation 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 SAUD80X145 Is Used
Twin-Tool Stamping
Drives two separate forming tools simultaneously from opposite rod ends, ensuring perfectly synchronized press cycles without adding a second cylinder.
Dual-End Diverting
Pushes a diverter arm from either side of a conveyor lane, providing identical 2268 N clamping force regardless of the direction of approach.
Is the Airtac SAUD Double Rod Cylinder SAUD80X145 the Right Cylinder?
Choose this 80 mm double-rod unit when your mechanism demands equal push and pull forces, specifically 2268 N at 0.5 MPa. If you need less force, the 63 mm bore delivers 1402 N both ways; if you require more, the 100 mm bore provides 3681 N. This model is the right call for anti-rotation tasks, twin-tool setups, or mounting a sensor cam on the back rod—though note this non-S SKU cannot carry a magnetic switch. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. At a 145 mm stroke, side loads are minimal, but always use external guides for longer strokes to prevent 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 SAUD80X145 FAQ
The force is equal in both directions because the rod exits both ends. It generates 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa. It operates on 3/8" ports with a speed range of 30-800 mm/s.
No, a plain double-rod cylinder drifts without live air; the 28 mm cushions only decelerate near stroke end and do not lock the piston. For suspended loads, install an external rod lock or pilot-operated check valve.
