Airtac SAUD Double Rod Cylinder SAUD80X185
The AirTAC SAUD Double Rod Cylinder SAUD80X185 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 185mm 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 SAUD80X185
The AirTAC SAUD80X185 is a double-acting, double-rod profile cylinder. A 25 mm rod exits both ends of the hard-anodized extruded aluminum barrel, meaning both faces use the rod-side piston area. This yields equal push and pull force of 2268 N each way at 0.5 MPa. The unit is notably shorter than an ISO 15552 cylinder of the same bore and uses a 3/8 inch port with an M20x1.5 rod thread.
Because the second rod protrudes from the back, it provides inherent anti-rotation guidance and can drive a second tool simultaneously. This specific SKU lacks a magnet, so it cannot accept CMSG or DMSG sensors. A high-temperature Viton H seal option extends operation from 0 to 150 C.

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 SAUD80X185 Is Used
Twin-Tool Stamping
Drives two synchronized forming tools from opposite rod ends, ensuring perfectly balanced impact without rotational drift.
Dual-End Diverting
Pushes a diverting blade from either side of a conveyor lane, providing equal 2268 N clamping force regardless of travel direction.
Mechanical Cam Tripping
Uses the extended back rod to physically trip a limit switch at mid-stroke, offering a reliable mechanical signal without requiring embedded magnets.
Is the Airtac SAUD Double Rod Cylinder SAUD80X185 the Right Cylinder?
Select this 80 mm bore if your application demands 2268 N of force in both directions over a 185 mm stroke. Stepping down to the 63 mm bore drops the equal force to 1402 N, while moving up to the 100 mm bore raises it to 3681 N. Choose a double-rod design when you need strict anti-twist guidance, synchronized twin tooling, or a back rod to trip a mechanical switch. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. Since this is a non-magnetized SKU, position sensing is unavailable. At 185 mm the side load is moderate, but always use external guide rails for heavy loads 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 SAUD80X185 FAQ
The force is equal in both directions because the 25 mm rod exits both ends. It generates 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, a plain double-rod cylinder drifts without live air; the adjustable 28 mm cushions only decelerate near stroke end. For suspended loads, install an external rod lock or pilot-operated check valve.
