Airtac SAUD Double Rod Cylinder SAUD80X25
The AirTAC SAUD Double Rod Cylinder SAUD80X25 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 25mm 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 SAUD80X25
The AirTAC SAUD80X25 is a double-acting, double-rod profile cylinder. A Ø25 mm rod protrudes from both ends, meaning both faces use the rod-side area. This yields equal push and pull force of 2268 N each way at 0.5 MPa. The extruded aluminium barrel is shorter than an ISO 15552 cylinder of the same bore.
This unit has a 3/8" port and 28 mm adjustable cushions. With no -S suffix, this SKU cannot take a magnetic sensor. A plain cylinder drifts on air loss; the cushion only decelerates, so use an external rod lock to hold loads.

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 SAUD80X25 Is Used
Twin-Tool Stamping
Drives two synchronized forming tools from one piston, ensuring parallel contact on sheet metal workpieces.
Dual-End Diverters
Pushes a diverter arm from either side of a belt line, maintaining equal clamping pressure in both directions.
Anti-Rotation Lifters
Lifts heavy pallets without twisting, using the twin rods to resist torque during vertical elevation.
Is the Airtac SAUD Double Rod Cylinder SAUD80X25 the Right Cylinder?
When sizing this 80 mm bore, note the 63 mm option provides 1402 N each way, while the 100 mm bore yields 3681 N at 0.5 MPa. Choose this double-rod model when your application demands anti-rotation guidance or needs to drive two tools at once. It shares FA and LB mounting with the AirTAC SC series. Because this SKU lacks the -S magnet, it cannot host CMSG or DMSG switches. The 25 mm stroke is short, so side-load guides are less critical here, but always support external bearings for any stroke over 300 mm.
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 SAUD80X25 FAQ
The force is equal both ways because both faces have a rod. It provides 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. This specific SKU lacks the internal magnet, so it cannot take CMSG, DMSG, or EMSG switches. You would need the SAUD80X25-S variant for position sensing.
