Airtac SAUD Double Rod Cylinder SAUD80X45
The AirTAC SAUD Double Rod Cylinder SAUD80X45 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 45mm 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 SAUD80X45
The AirTAC SAUD80X45 is a double-acting, double-rod profile cylinder. A Ø25 mm rod exits both ends of the hard-anodized aluminum extruded barrel, meaning both faces use the rod-side area. This yields exactly 2268 N of output force each way at 0.5 MPa. The unit is notably shorter than a standard ISO 15552 cylinder of the same bore, and mounting hardware is compatible with the AirTAC SC series.
Because the piston travels symmetrically, this model excels at anti-rotation tasks and driving twin tooling. The 3/8 inch port and 28 mm adjustable air cushions manage the 30-800 mm/s speed range. Note this SKU lacks a magnet, so it cannot accept CMSG or DMSG switches.

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 SAUD80X45 Is Used
Twin-Spindle Drilling
Drives two synchronized machining spindles from one piston, ensuring parallel hole patterns without torsional deflection.
Dual Transfer Pushers
Simultaneously indexes two pallets on adjacent conveyor lanes, maintaining perfect timing via the shared rigid rod.
Gripper Cam Actuation
Uses the protruding back rod as a mechanical cam to trip a sequence of external limit valves during the stroke.
Is the Airtac SAUD Double Rod Cylinder SAUD80X45 the Right Cylinder?
Select this 80 mm bore if your application requires equal push and pull thrust, specifically 2268 N in both directions at 0.5 MPa. If you need less force, the 63 mm bore delivers 1402 N both ways; for heavier drives, the 100 mm bore provides 3681 N. A double-rod design is the right call when you need synchronized twin tooling or inherent anti-twist guidance. Mounting is limited to Basic, FA flange, and LB foot styles. Since this specific SKU has no -S magnet, position sensing is impossible without external contacts. At a 45 mm stroke, side-load stress is minimal, but always guide the load externally on longer strokes.
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 SAUD80X45 FAQ
The thrust is equal in both directions because both faces lose area to the Ø25 mm rod. It generates 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa. Operating pressure ranges from 0.15 to 1.0 MPa.
No. A plain SAUD cylinder drifts without live air; the 28 mm adjustable cushions only decelerate the piston near the end caps. For suspended loads, install an external rod lock or a pilot-operated check valve.
