Airtac SAUD Double Rod Cylinder SAUD80X125
The AirTAC SAUD Double Rod Cylinder SAUD80X125 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 125mm 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 SAUD80X125
The AirTAC SAUD80X125 is a double-acting, double-rod profile cylinder. Because a rod exits both ends, the push and pull forces are equal at 2268 N each way at 0.5 MPa. The extruded aluminium barrel makes it shorter than an ISO 15552 cylinder of the same bore. It features a 3/8" port, a 25 mm rod, and M20x1.5 rod threads.
This twin-rod design provides anti-rotation guidance and lets you drive two tools at once. A Viton H seal option extends operation to 150 C. This SKU lacks a magnet, so it cannot take a sensor switch.

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 SAUD80X125 Is Used
Twin-Spindle Drilling
Drives two synchronized machining heads from one piston, keeping thrust identical in both directions for consistent tool pressure.
Transfer Pusher
Pushes parts across a belt on the forward stroke and retracts a secondary kicker on the back stroke using the rear rod.
Pallet Lift Stop
Uses the equal push and pull force to halt heavy pallets securely without twisting, ensuring stable vertical alignment.
Is the Airtac SAUD Double Rod Cylinder SAUD80X125 the Right Cylinder?
Choose this 80 mm bore when you need 2268 N of equal bidirectional force. If you need less, the 63 mm bore delivers 1402 N; if you need more, the 100 mm bore provides 3681 N. A double rod is ideal for anti-rotation, twin tooling, or back-end sensing. Mounting is limited to Basic, FA, and LB styles, matching the AirTAC SC series. The 125 mm stroke is short enough to avoid side-load guide issues. Remember this SKU has no magnet, so sensing is impossible. For load holding on air loss, add an external rod lock, as the cushions only decelerate.
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 SAUD80X125 FAQ
The force is equal in both directions because it is a 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" port feeds both chambers equally.
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors. You would need the -S variant for switch readiness. The rear rod is still useful for mechanical cam actuation.
