Airtac SAUD Double Rod Cylinder SAUD80X155S
The AirTAC SAUD Double Rod Cylinder SAUD80X155S 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 SAUD80X155S
The AirTAC SAUD80X155S 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 piston area. This yields exactly 2268 N of output force in both directions at 0.5 MPa. The 3/8 inch port feeds the 80mm bore, and the unit runs at 30-800 mm/s.
Because the extruded profile body is shorter than a standard ISO 15552 cylinder of the same bore, it saves machine space. The -S suffix means a piston magnet is built in for CMSG, DMSG, or EMSG 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 SAUD80X155S Is Used
Twin-Tool Synchronization
Drives two opposing grippers or tools simultaneously from one piston, ensuring perfectly matched timing without external linkages.
Back-Rod Switch Cam
Uses the protruding rear rod to trip a CMSG or DMSG sensor directly, freeing the front end entirely for the primary work tool.
Balanced Vertical Lift
Provides identical push and pull force to raise and lower a 116kg payload smoothly without the asymmetry of a single-rod actuator.
Is the Airtac SAUD Double Rod Cylinder SAUD80X155S the Right Cylinder?
Choose this 80mm bore (2268 N both ways at 0.5 MPa) if you need high equal force with anti-rotation stability. Step down to the 63mm bore for 1402 N, or up to the 100mm bore for 3681 N. A double rod is the right call for twin-tool driving, synchronized lifting, or mounting a switch cam on the back rod. Mounting is limited to Basic, FA, and LB types matching the AirTAC SC series. With a 155mm stroke, side loads are moderate, but always guide the load externally for smooth operation. The -S magnet enables position sensing.
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 SAUD80X155S FAQ
Because it is a double-rod cylinder, the force is equal in both directions. It provides 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa. The 80mm bore uses a 3/8 inch port.
No, a plain SAUD cylinder will drift without live air. The adjustable 28mm cushions only decelerate the piston near the stroke ends; they do not lock it. Use an external rod lock or pilot-operated check valve for secure load holding.
