Airtac SAUD Double Rod Cylinder SAUD63X30S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD63X30S is a genuine double-acting profile-type standard air cylinder with a Ø63mm bore and 30mm 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 SAUD63X30S
The AirTAC SAUD63X30S is a double-acting, double-rod profile cylinder. A 63mm bore with a 30mm stroke yields identical push and pull thrust of 1402 N at 0.5 MPa, as both faces share the identical rod-side area. The 3/8 inch port feeds this symmetric action.
Built on an extruded aluminum profile, it is shorter than an ISO 15552 unit of the same bore. The -S suffix provides a piston magnet for CMSG, DMSG or EMSG switches. As a computed buyer insight, the safe working load is roughly 841 N, allowing a vertical lift of about 71 kg with a 2:1 margin. Viton H seals can raise the operating ceiling to 150 C.

Where the Airtac SAUD Double Rod Cylinder SAUD63X30S Is Used
Gripper Synchronization
Drives dual pick-and-place grippers from both rod ends simultaneously to keep tooling perfectly aligned during short 30mm transfers.
Cam-Triggered Ejection
Uses the protruding back rod as a mechanical cam to trip a limit switch, confirming the ejection stroke completed without adding external sensors.
Anti-Twist Clamping
Holds a machined workpiece flat against a fixture face, using the symmetric double-rod geometry to resist torsional deflection under load.
Is the Airtac SAUD Double Rod Cylinder SAUD63X30S the Right Cylinder?
Select this 63mm bore when you need 1402 N of equal both-ways thrust at 0.5 MPa. Step down to a 50mm bore for 825 N, or up to an 80mm bore for 2268 N. The twin rods prevent rotation and allow mounting a sensor cam on the back end. Use FA or LB mounts compatible with the AirTAC SC series. The -S magnet enables position sensing. At 30mm stroke, side-load risk is minimal, but always guide external loads to prevent 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 SAUD63X30S FAQ
Because the piston rod exits both ends, the force is equal in both directions. It generates 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and 2523 N at 0.9 MPa. The 3/8 inch port supplies air to both chambers.
No. A plain SAUD cylinder will drift on air loss or when the valve is centered. The adjustable air cushion only decelerates the piston near the stroke ends; it does not lock the load. For secure holding, install an external rod lock or a pilot-operated check valve.
