Airtac SAUD Double Rod Cylinder SAUD80X85
The AirTAC SAUD Double Rod Cylinder SAUD80X85 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 85mm 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 SAUD80X85
The AirTAC SAUD80X85 is a double-acting, double-rod profile cylinder. An 80mm bore with an 85mm stroke yields 2268 N of thrust and pull at 0.5 MPa, making the output equal in both directions. It features a 3/8 inch port and a 25mm rod at each end.
Because the rod exits both faces, this unit prevents rotation and can drive twin tooling simultaneously. The extruded aluminum body is shorter than a standard ISO 15552 cylinder of the same size. Without a magnet, this SKU cannot take a sensor.

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 SAUD80X85 Is Used
Synchronized Transfer
Drives opposing pusher arms on a packaging line simultaneously, keeping product spacing exact without twisting.
Twin-Spindle Drill
Advances two machining heads in parallel, ensuring both holes are bored to identical depth on a single stroke.
Balanced Press Down
Applies even clamping pressure from both rod ends to secure a workpiece without inducing lateral skew.
Is the Airtac SAUD Double Rod Cylinder SAUD80X85 the Right Cylinder?
When sizing this 80mm bore, the adjacent 63mm version provides 1402 N each way, while the 100mm bore offers 3681 N at 0.5 MPa. Choose this double-rod layout when your mechanism demands anti-rotation guidance, needs to carry a switch cam on the back rod, or drives two tools at once. Mounting is limited to Basic, FA, and LB styles, sharing compatibility with the AirTAC SC series. Because this specific SKU lacks the -S magnet suffix, it cannot accept CMSG, DMSG, or EMSG sensors. For this 85mm stroke, side loads remain manageable, but any application over 300mm requires an external guide to prevent 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 SAUD80X85 FAQ
The force is equal in both directions because rods exit both ends. It produces 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa.
No, a plain cylinder drifts on air loss; the 28mm adjustable cushion only decelerates near stroke end. Use an external rod lock or pilot-operated check valve for secure load holding.
