Airtac SAUD Double Rod Cylinder SAUD80X145S
The AirTAC SAUD Double Rod Cylinder SAUD80X145S 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 SAUD80X145S
The AirTAC SAUD80X145S is a double-acting, double-rod profile cylinder. A Ø25mm rod protrudes from both ends of the hard-anodized aluminum extruded barrel, meaning push and pull forces are identical at 2268 N each way at 0.5 MPa. This compact body is shorter than a standard ISO 15552 unit of the same 80mm bore, and the 3/8" port drives a swift 30-800 mm/s speed.
Because the rear rod can carry a switch cam, the factory -S magnet option lets you mount CMSG, DMSG or EMSG sensors for end-position signaling. The twin-rod geometry provides inherent anti-rotation guidance for synchronized tooling.

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 SAUD80X145S Is Used
Twin-Tool Transfer
Drives two synchronized grippers from one body, utilizing the equal push and pull force to shuttle parts between machining stations without rotational drift.
Guided Cutting Press
Powers a symmetrical cutting blade where the dual rods prevent yaw under high offset loads, maintaining precise vertical blade alignment.
Rear-Cam Sensing
Uses the protruding back rod to physically trip a limit switch or carry a magnetic sensor cam in space-constrained packaging machinery.
Is the Airtac SAUD Double Rod Cylinder SAUD80X145S the Right Cylinder?
Select this 80mm bore model when your mechanism requires strict non-rotating accuracy or needs to drive two tools at once. Sizing up or down is straightforward: the 63mm neighbor yields 1402 N both ways, while the 100mm version provides 3681 N. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. The included -S magnet supports electronic and reed switches. For this 145mm stroke, ensure external load guides are used to prevent side-load 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 SAUD80X145S FAQ
The force is equal in both directions because it is a 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. The adjustable 28mm air cushions only decelerate the piston near the stroke ends; they do not lock it. For load holding on air loss, you must fit an external rod lock or pilot-operated check valve.
