Airtac SAUD Double Rod Cylinder SAUD80X135
The AirTAC SAUD Double Rod Cylinder SAUD80X135 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 135mm 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 SAUD80X135
The AirTAC SAUD80X135 is a double-acting, double-rod profile cylinder. An 80mm bore with a 135mm stroke yields equal force in both directions, delivering 2268N at 0.5MPa. The extruded aluminum barrel makes it shorter than an ISO 15552 unit of the same bore. A 3/8 inch port supplies air, and the M20x1.5 rod threads mate with standard knuckles.
Because a rod exits both ends, this SKU provides anti-rotation guidance and can drive twin tools simultaneously. Without the -S magnet option, this specific model cannot accept CMSG, DMSG, or EMSG sensors. The 28mm adjustable air cushions decelerate the piston near stroke end, but a plain cylinder drifts without live air; use an external rod lock or pilot-operated check valve for secure load holding.

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 SAUD80X135 Is Used
Twin-Spindle Drilling
Drives two synchronized machining heads from one piston, ensuring both holes are bored to identical depths without rotational twist.
Dual Pneumatic Diverter
Pushes a pair of sorting flaps simultaneously on a packaging line, keeping the diverter gate perfectly parallel during high-speed transit.
Symmetric Lift Fixture
Raises and lowers a heavy palletizing jig with equal force both ways, preventing the platform from canting during vertical transfer.
Is the Airtac SAUD Double Rod Cylinder SAUD80X135 the Right Cylinder?
Select this 80mm bore when your application requires 2268N of equal push and pull force at 0.5MPa. If you need less thrust, step down to the 63mm bore (1402N both ways); if you need more, the 100mm bore provides 3681N. A double-rod design is the right call for anti-rotation stability, twin-tool driving, or mounting a switch cam on the back rod. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. Remember that this non-magnet SKU cannot host sensors. For any stroke at or over 300mm, always use 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 SAUD80X135 FAQ
Because this is a double-rod cylinder, the force is equal in both directions. It outputs 2268N at 0.5MPa, 3175N at 0.7MPa, and 4082N at 0.9MPa. The 3/8 inch port feeds the 80mm bore to achieve these figures.
No, this specific SKU lacks the internal magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for position sensing. The double-rod design still allows you to mount a mechanical cam on the back rod to trip an external switch.
