Airtac SAUD Double Rod Cylinder SAUD80X800
The AirTAC SAUD Double Rod Cylinder SAUD80X800 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 800mm 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 SAUD80X800
The AirTAC SAUD80X800 is a double-acting, double-rod profile cylinder with an 80mm bore and 800mm stroke. A 25mm rod exits both ends, meaning both faces use the rod-side piston area. This yields exactly 2268 N of output force at 0.5 MPa in both directions. The extruded aluminium barrel keeps the body shorter than an ISO 15552 unit of the same bore. It uses a 3/8 inch port and M20x1.5 rod threads.
Because the rod protrudes at the back, you can mount a sensor cam or drive twin tools with anti-rotation guidance. This SKU lacks a magnet, so it cannot host CMSG or DMSG switches. A 28mm adjustable air cushion decelerates the piston at each end, but an external rod lock is required to hold a load on air loss.

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 SAUD80X800 Is Used
Dual-Tool Transfer
Drives two opposing grippers simultaneously on a conveyor line, using the equal both-ways force to push and pull parts with identical 2268 N authority.
Synchronized Pressing
Applies matched clamping pressure from both ends of a machining fixture, keeping the workpiece centered without requiring a larger single-rod push cylinder.
Is the Airtac SAUD Double Rod Cylinder SAUD80X800 the Right Cylinder?
Choose this 80mm bore when you need 2268 N both ways at 0.5 MPa. Stepping down, the 63mm bore provides 1402 N, while stepping up to the 100mm bore yields 3681 N. A double rod is the right call for anti-rotation tasks, twin-tool setups, or back-end cam tripping. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. At 800mm stroke, you must use external guides to prevent rod bending and side-load damage. Without the -S magnet option, this specific SKU cannot accept magnetic sensors.
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 SAUD80X800 FAQ
The force is equal in both directions because the 25mm rod exits 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 at speeds of 30-800 mm/s.
No. The 28mm adjustable air cushions only decelerate the piston near the stroke ends; they do not lock the position. If air is lost, the load will drift. You must add an external rod lock or a pilot-operated check valve to hold a load safely.
