Airtac SAUD Double Rod Cylinder SAUD80X240
The AirTAC SAUD Double Rod Cylinder SAUD80X240 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 240mm 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 SAUD80X240
The AirTAC SAUD80X240 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 identical rod-side area. This yields an equal push and pull force of 2268 N at 0.5 MPa. The unit is notably shorter than a conventional 80 mm bore cylinder and uses a 3/8 inch port with M20x1.5 rod threads.
Because the piston travels 240 mm, the dual rods provide excellent anti-rotation stability and can drive twin tooling simultaneously. This plain SKU lacks a magnet, so it cannot accept position switches. The 28 mm adjustable air cushions decelerate the payload at stroke ends, but an external rod lock is required to hold a load on air loss.

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 SAUD80X240 Is Used
Dual Transfer Pushers
Drives two synchronized pusher plates on a conveyor line from a single compact body, ensuring parallel contact without torsional twisting.
Twin Tool Lifting
Lifts and lowers two identical machining fixtures simultaneously, using the equal both-ways force to maintain balanced vertical motion.
Mechanical Cam Tripping
Uses the extended back rod to physically trip a limit switch at mid-stroke, ideal for rigid automation sequencing without sensors.
Is the Airtac SAUD Double Rod Cylinder SAUD80X240 the Right Cylinder?
When sizing this 80 mm bore unit, step down to the 63 mm bore for 1402 N, or step up to the 100 mm bore for 3681 N, both equal in both directions at 0.5 MPa. Select this double-rod model when your mechanism needs strict anti-twist guidance, synchronized twin tooling, or a back rod to trip a mechanical switch. It shares FA and LB mounting dimensions with the AirTAC SC series. Since this is a non-magnetized SKU, you cannot mount CMSG or DMSG sensors. At a 240 mm stroke, side loading is minimal, but always guide the load externally to prevent binding. Remember the cushions only decelerate; use a pilot-operated check valve for pneumatic load holding.
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 SAUD80X240 FAQ
The force is equal in both directions because the 25 mm 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 equally.
No. This specific SKU is built without a piston magnet, so it cannot trigger CMSG or DMSG switches. You must rely on the back rod to trip an external mechanical limit switch, or select a different magnetized model.
