Airtac SAUD Double Rod Cylinder SAUD80X850S
The AirTAC SAUD Double Rod Cylinder SAUD80X850S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 850mm 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 SAUD80X850S
The AirTAC SAUD80X850S is a double-acting, double-rod profile cylinder with an 80 mm bore and an 850 mm stroke. A rod protrudes from both ends, meaning both faces use the rod-side piston area. This yields an identical push and pull output of 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa. The unit includes a magnetic piston (-S) for CMSG, DMSG, or EMSG switches, uses a 3/8 inch port, and features M20x1.5 rod threads.
Built with an extruded aluminum profile barrel, this unit is shorter than a standard ISO 15552 cylinder of the same bore. The dual-rod architecture provides inherent anti-rotation guidance and allows a sensor cam to ride the back rod. An adjustable 28 mm air cushion decelerates the piston at stroke ends, but does not lock the load.

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 SAUD80X850S Is Used
Dual-Tool Transfer
Drives two synchronized pick-and-place heads from one piston, ensuring parallel tool movement without twist.
Cam-Triggered Positioning
Uses the extended back rod to physically trip a limit switch or carry a CMSG sensor cam externally.
Is the Airtac SAUD Double Rod Cylinder SAUD80X850S the Right Cylinder?
Select this 80 mm bore model when your application demands equal force in both directions, such as twin-tool driving or non-rotating lift fixtures. The 2268 N output at 0.5 MPa sits between the 63 mm bore (1402 N) and the 100 mm bore (3681 N). If your fixture requires less force, step down to the 63 mm; if you need heavier thrust, step up to the 100 mm. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. The included -S magnet supports reed and electronic sensing. Because the stroke is 850 mm, you must use external guide rails to prevent rod bending and manage side loads.
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 SAUD80X850S FAQ
Because it is a double-rod cylinder, the force is equal in both directions: 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa. It uses a 3/8 inch port and has an adjustable 28 mm cushion at both ends.
No, the air cushion only decelerates the piston near the end of the stroke. To hold a load securely on air loss, you must add an external rod lock or a pilot-operated check valve.
