Airtac SAUD Double Rod Cylinder SAUD80X270
The AirTAC SAUD Double Rod Cylinder SAUD80X270 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 270mm 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 SAUD80X270
The AirTAC SAUD80X270 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 is shorter than an ISO 15552 cylinder of the same 80 mm bore. It features a 3/8 inch port, an M20x1.5 rod thread, and adjustable 28 mm air cushions at both ends.
Because both faces lose rod area, output is perfectly balanced. This plain SKU lacks a magnet, so it cannot take CMSG or DMSG sensors. For high heat up to 150 C, specify the Viton H seal option.

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 SAUD80X270 Is Used
Twin-Spindle Drilling
Drives two synchronized machining heads from opposite rod ends with equal 2268 N thrust to prevent workpiece twisting.
Dual Transfer Pushers
Pushes pallets in alternating directions using both strokes, maintaining identical force for seamless line handoffs.
Gripper Cam Actuation
Uses the extended back rod as a mechanical cam to trip external limit valves during the return stroke.
Is the Airtac SAUD Double Rod Cylinder SAUD80X270 the Right Cylinder?
Choose this 80 mm bore (2268 N both ways) if you need synchronized motion or anti-twist guidance. Stepping down, the 63 mm bore provides 1402 N both ways; stepping up, the 100 mm bore yields 3681 N. A double rod is ideal for carrying a switch cam on the back or driving two tools. Mounting is limited to Basic, FA flange, and LB foot, matching the AirTAC SC series. Since the 270 mm stroke exceeds 300 mm, ensure external guide rails to prevent side-load 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 SAUD80X270 FAQ
Force is equal in both directions because rods exit both ends. It delivers 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 equally.
No. The air cushions only decelerate near stroke end; they do not lock the piston. If air drops, the load drifts. Use an external rod lock or pilot-operated check valve for secure holding.
