Airtac SAUD Double Rod Cylinder SAUD80X260S
The AirTAC SAUD Double Rod Cylinder SAUD80X260S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 260mm 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 SAUD80X260S
The AirTAC SAUD80X260S is a double-acting, double-rod profile cylinder. A Ø25 mm rod protrudes from both ends, meaning both faces use the rod-side piston area. This yields an identical output of 2268 N each way at 0.5 MPa. The extruded hard-anodized aluminum barrel keeps the body shorter than an ISO 15552 unit of the same bore.
This -S variant includes a piston magnet for CMSG, DMSG, or EMSG switches. It features a 3/8 inch port, M20x1.5 rod threads, and 28 mm adjustable air cushions at both ends. A high-temperature Viton H seal option can extend operation up 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 SAUD80X260S Is Used
Twin-Tool Machining
Drives two opposing machining heads simultaneously with identical 2268 N force, keeping cycle times synchronized on both ends.
Rear-Cam Position Sensing
Uses the extended back rod to trip a CMSG or DMSG switch, providing precise end-of-stroke confirmation in confined spaces.
Is the Airtac SAUD Double Rod Cylinder SAUD80X260S the Right Cylinder?
Choose this 80 mm bore when your application demands equal push and pull forces, such as anti-rotation guidance or driving twin tooling simultaneously. Stepping down, the 63 mm bore provides 1402 N each way at 0.5 MPa; stepping up, the 100 mm bore offers 3681 N. The rear protruding rod is ideal for mounting a sensor cam. Mounting is limited to Basic, FA, and LB types, matching the AirTAC SC series. At 260 mm stroke, external load guides are recommended to prevent side-load binding. Remember that air cushions only decelerate; use an external rod lock or pilot-operated check valve to hold a load securely without live air.
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 SAUD80X260S FAQ
Because the 25 mm rod exits both ends, the force is equal in both directions: 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa. It never produces a larger single-rod push value.
No, a plain double-rod cylinder will drift without live air. The adjustable 28 mm cushions only decelerate the piston near the end of travel. For secure load holding, you must install an external rod lock or a pilot-operated check valve.
