Airtac SAUD Double Rod Cylinder SAUD80X135S
The AirTAC SAUD Double Rod Cylinder SAUD80X135S 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 SAUD80X135S
The AirTAC SAUD80X135S is a double-acting, double-rod profile cylinder. A 25 mm rod exits both ends, meaning both faces use the rod-side area. Push and pull force are equal at 2268 N each way at 0.5 MPa. The extruded aluminium barrel makes it shorter than an ISO 15552 cylinder of the same bore. It has a 3/8 inch port and M20x1.5 rod thread.
Because the rod protrudes at the back, you can mount a switch cam directly on it for CMSG, DMSG or EMSG sensors. The -S suffix confirms the built-in magnet is present. Standard 28 mm adjustable air cushions decelerate the piston near stroke end, but a plain cylinder drifts without live air, so use an external rod lock to hold a load.

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 SAUD80X135S Is Used
Twin-Spindle Machining
Drives two opposing machining heads simultaneously with equal 2268 N force, keeping cycle times synchronized.
Dual Transfer Pusher
Pushes a workpiece forward while the back rod trips a rear-mounted sensor cam to confirm stroke completion.
Is the Airtac SAUD Double Rod Cylinder SAUD80X135S the Right Cylinder?
Select this 80 mm bore if your application needs anti-rotation guidance or twin tooling driven from both rod ends. The equal both-ways force is 2268 N at 0.5 MPa. Stepping down, the 63 mm bore gives 1402 N. Stepping up, the 100 mm bore yields 3681 N. Mounting is limited to Basic, FA flange and LB foot, matching the AirTAC SC series. The -S magnet allows position sensing. For this 135 mm stroke, ensure external guide rails carry any heavy side loads to prevent rod 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 SAUD80X135S FAQ
The force is equal in both directions because it is a double-rod cylinder. 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 supplies air to both chambers.
The protruding back rod provides anti-rotation stability and can carry a switch cam for CMSG or DMSG sensors. The -S magnet enables this rear-end sensing, and the compact profile barrel is shorter than standard ISO cylinders.
