Airtac SAUD Double Rod Cylinder SAUD63X120S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD63X120S is a genuine double-acting profile-type standard air cylinder with a Ø63mm bore and 120mm 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 SAUD63X120S
The AirTAC SAUD63X120S is a double-acting, double-rod profile cylinder. A piston rod exits both ends, meaning both faces use the rod-side area. This makes the push and pull force equal, delivering 1402 N each way at 0.5 MPa. The extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same 63 mm bore. It features a 3/8" port and an M16x1.5 rod thread.
This 120 mm stroke model includes a built-in piston magnet (-S) for CMSG, DMSG, or EMSG switches. The equal force makes it ideal for anti-rotation guidance or driving twin tools. Based on the 1402 N output, the safe working load is about 841 N, and it can vertically lift roughly 71 kg with a 2:1 margin. A Viton H seal option raises the operating temperature to 150 C.

Where the Airtac SAUD Double Rod Cylinder SAUD63X120S Is Used
Twin-Tool Machining
Drives two opposing machining heads simultaneously with equal 1402 N force, ensuring balanced material removal.
Anti-Rotation Lifting
Lifts loads up to 71 kg vertically without twisting, using the inherent guidance of the dual rod structure.
Cam-Actuated Sensing
Uses the protruding back rod to trip an external limit switch or carry a CMSG sensor cam for precise timing.
Is the Airtac SAUD Double Rod Cylinder SAUD63X120S the Right Cylinder?
Choose this 63 mm bore when you need 1402 N of equal force in both directions. If you need less force, the 50 mm bore provides 825 N both ways. If you need more, the 80 mm bore offers 2268 N both ways. A double rod is the right call for synchronized twin tooling, non-rotating loads, or mounting a switch cam on the back rod. Mounting is limited to Basic, FA flange, and LB foot, matching the AirTAC SC series. The -S magnet allows electronic position sensing. For this 120 mm stroke, external side-load guides are recommended 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 SAUD63X120S FAQ
Because it is a double-rod cylinder, the force is equal in both directions. It provides 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 double-rod cylinder drifts without live air. The adjustable 21 mm cushions only decelerate the piston near the stroke ends. To hold a load securely, use an external rod lock or a pilot-operated check valve.
