Airtac SAUD Double Rod Cylinder SAUD80X165S
The AirTAC SAUD Double Rod Cylinder SAUD80X165S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 165mm 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 SAUD80X165S
The AirTAC SAUD80X165S is a double-acting, double-rod profile cylinder. A 25mm rod exits both ends of the hard-anodized aluminum barrel, meaning both faces use the rod-side area. Output is equal in both directions at 2268 N each way at 0.5 MPa. The extruded profile body is noticeably shorter than an ISO 15552 cylinder of the same 80mm bore.
Because the stroke is 165mm, side-load risks are low, but external guides remain best practice for rigid twin-tool setups. The built-in magnet (-S) supports CMSG, DMSG, and EMSG switches. The 3/8 inch port and M20x1.5 rod thread match the 80mm bore standard.

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 SAUD80X165S Is Used
Twin-Tool Punching
Drives two synchronized forming tools from one piston, using the equal both-ways force to punch and retract identically.
Dual Transfer Arms
Shifts parts across a belt using both rod ends simultaneously, keeping the motion balanced without twisting.
Cam-Triggered Sorting
Uses the extended back rod as a switch cam to trip external sensors at mid-stroke for high-speed diverting.
Is the Airtac SAUD Double Rod Cylinder SAUD80X165S the Right Cylinder?
Select this 80mm bore model when your mechanism requires true equal push and pull force, such as anti-rotation guidance or driving two tools at once. If you need less force, the 63mm bore provides 1402 N both ways; if you need more, the 100mm bore yields 3681 N both ways. Mounting is limited to Basic, FA flange, and LB foot styles, sharing compatibility with the AirTAC SC series. The -S suffix means a piston magnet is already included for position sensing. For any stroke at or above 300mm, add external load 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 SAUD80X165S FAQ
The force is equal both ways because it is a double-rod cylinder. It outputs 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa. The 3/8 inch port feeds both chambers equally.
No, a plain double-rod cylinder drifts without live air. The adjustable air cushions only decelerate the piston near the stroke ends. To hold a load, install an external rod lock or a pilot-operated check valve.
