Airtac SAUD Double Rod Cylinder SAUD80X900
The AirTAC SAUD Double Rod Cylinder SAUD80X900 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 900mm 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 SAUD80X900
The AirTAC SAUD80X900 is a double-acting, double-rod profile cylinder. A rod protrudes from both ends, meaning push and pull forces are identical at 2268 N each way at 0.5 MPa. The extruded aluminum barrel keeps the unit shorter than an ISO 15552 cylinder of the same bore. It features a 3/8 inch port, a 25 mm rod, and M20x1.5 rod threads.
Because both faces lose rod area, output is symmetrical, making it ideal for anti-rotation or twin-tool tasks. This SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors. A Viton H seal option raises the operating ceiling 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 SAUD80X900 Is Used
Dual-Tool Transfer
Drives two synchronized pickers on a single piston to move parts across a conveyor without torsional twist.
Symmetric Clamping
Applies equal 2268 N clamping pressure from both rod ends to hold a workpiece centrally during milling.
Vertical Lift Station
Raises a 116 kg payload using the back rod as a mechanical stop cam for elevated storage racks.
Is the Airtac SAUD Double Rod Cylinder SAUD80X900 the Right Cylinder?
When sizing this 80 mm bore against its neighbors, the 63 mm yields 1402 N and the 100 mm provides 3681 N, both equal in both directions at 0.5 MPa. Choose this double-rod model when you need synchronized motion, resistance to torsional twist, or a back rod to trip a switch. Mounting is limited to Basic, FA, and LB types compatible with the AirTAC SC series. Since the 900 mm stroke exceeds 300 mm, fit external guides to prevent rod bending and side-load damage. Note that this non-magnetic version cannot host position sensors.
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 SAUD80X900 FAQ
Force is equal in both directions because a rod exits both ends. 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 at speeds of 30-800 mm/s.
No. The air cushions only decelerate the piston near the stroke ends; they do not lock the load. If air is lost, the piston drifts. For secure load holding, install an external rod lock or a pilot-operated check valve.
