Airtac SAUD Double Rod Cylinder SAUD80X70
The AirTAC SAUD Double Rod Cylinder SAUD80X70 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 70mm 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 SAUD80X70
The AirTAC SAUD80X70 is a double-acting, double-rod profile cylinder. A Ø25 mm rod exits both ends of the hard-anodized aluminum barrel, meaning both faces use the rod-side area. Output is equal in extension and retraction at 2268 N each way at 0.5 MPa. The 3/8 inch port and M20x1.5 rod thread handle robust airflow and mounting.
This extruded profile body is shorter than an ISO 15552 unit of the same bore. The twin rods prevent rotation and can drive dual tools simultaneously. Note this SKU lacks a magnet, so it cannot host CMSG or DMSG 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 SAUD80X70 Is Used
Twin-Tool Stamping
Drives two matched forming tools from one piston, ensuring perfectly synchronized contact on sheet metal workpieces.
Dual Pusher Array
Pushes cartons from both rod ends alternately to feed a packaging line without adding a second valve.
Lifting Fork
Raises and lowers a transfer fork with equal power both directions, resisting twist during vertical payload shifts.
Is the Airtac SAUD Double Rod Cylinder SAUD80X70 the Right Cylinder?
Choose this 80 mm bore delivering 2268 N both ways when you need precise anti-rotation guidance or twin-tool drive. If less force is needed, the 63 mm bore provides 1402 N both ways; if more is required, step up to the 100 mm bore for 3681 N. Mounting is limited to Basic, FA flange, and LB foot options, compatible with AirTAC SC series parts. Because this SKU has no -S magnet, position sensing is impossible without changing the model. For any application over 300 mm stroke, add external guide rails to prevent side-load 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 SAUD80X70 FAQ
The force is equal in both directions due to the double-rod design. 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. The adjustable 28 mm air cushions only decelerate the piston near stroke end; they do not lock the load. For holding a vertical load during air loss, you must fit an external rod lock or pilot-operated check valve.
