Airtac SAUD Double Rod Cylinder SAUD80X900S
The AirTAC SAUD Double Rod Cylinder SAUD80X900S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 900mm 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 SAUD80X900S
The AirTAC SAUD80X900S is a double-acting, double-rod profile cylinder. A 25mm rod exits both ends of the hard-anodized aluminum extruded barrel, meaning both faces use the rod-side piston area. This yields exactly 2268 N of thrust and retract force at 0.5 MPa. The extruded profile is noticeably shorter than an ISO 15552 unit of the same 80mm bore. It uses a 3/8 inch port and M20x1.5 rod threads.
With a 900mm stroke, external side-load guidance is strongly recommended to prevent rod bending. Because it is a double-rod design, the back rod can drive a second tool or carry a switch cam. The -S suffix indicates a built-in magnet for CMSG, DMSG or EMSG sensors.

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 SAUD80X900S Is Used
Dual-Tool Transfer
Drives two synchronized grippers from one piston, using both protruding rods to push and pull parts simultaneously on an assembly line.
Anti-Twist Lift
The twin rods prevent mechanical twist during the 900mm elevation cycle.
Cam-Triggered Sorting
Uses the rear rod extension to trip an external limit switch, while the internal -S magnet fires CMSG sensors for position feedback.
Is the Airtac SAUD Double Rod Cylinder SAUD80X900S the Right Cylinder?
Select this 80mm bore when you need 2268 N equal both ways. Step down to a 63mm bore for 1402 N, or up to a 100mm bore for 3681 N. A double rod is the right call for anti-rotation guidance, twin tooling, or back-end sensing. Mounting is limited to Basic, FA flange, and LB foot brackets, matching the AirTAC SC series. The -S magnet supports reed and electronic switches. At 900mm stroke, always use an external guide to absorb side loads and prevent rod bending.

- ✓ 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 SAUD80X900S FAQ
Force is equal in both directions because rods protrude from both ends. It delivers 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.
No. The adjustable 28mm air cushions only decelerate the piston near stroke end. To hold a load on air loss, install an external rod lock or pilot-operated check valve.
