Airtac SAUD Double Rod Cylinder SAUD63X280S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD63X280S is a genuine double-acting profile-type standard air cylinder with a Ø63mm bore and 280mm 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 SAUD63X280S
The AirTAC SAUD63X280S is a double-acting, double-rod profile cylinder. A 63mm bore with a 280mm stroke yields equal push and pull thrust of 1402 N at 0.5 MPa. The piston rod protrudes from both end caps, meaning both faces use the identical rod-side area. This specific unit includes the -S magnet option for position sensing.
Because it uses an extruded aluminum profile barrel, the body is notably shorter than a standard ISO 15552 cylinder of the same bore. The 3/8" port drives a 30-800 mm/s speed range. For sizing, the 0.5 MPa output gives a safe working load of roughly 841 N, translating to a vertical lift capacity of about 71 kg with a 2:1 safety margin. A Viton H seal can raise the operating ceiling to 150 C.

Where the Airtac SAUD Double Rod Cylinder SAUD63X280S Is Used
Twin-Tool Stamping
Drives two synchronized forming tools from one piston, ensuring parallel contact and equal 1402 N clamping on both faces.
Anti-Rotation Diverter
Uses the dual protruding rods to push a sorting gate without twisting, maintaining precise alignment across the 280mm travel.
Cam-Triggered Cutting
Mounts a trip cam on the rear rod to signal a blade valve, using the -S magnet for primary end-of-stroke confirmation.
Is the Airtac SAUD Double Rod Cylinder SAUD63X280S the Right Cylinder?
Choose this 63mm bore when you need 1402 N of thrust in both directions. If your project requires less force, the 50mm bore provides 825 N; if you need more, step up to the 80mm bore for 2268 N. The double-rod architecture is ideal for anti-rotation guidance, driving twin tooling, 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. At 280mm stroke, external load guides are recommended to prevent side-loading wear on the seals. The -S suffix enables CMSG, DMSG, or EMSG sensors.
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 SAUD63X280S FAQ
The force is equal in both directions because it is a double-rod design. It outputs 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and 2523 N at 0.9 MPa.
No. A plain SAUD cylinder drifts without live air; the adjustable cushions only decelerate near the stroke ends. Use an external rod lock or pilot-operated check valve for secure load holding.
