Airtac SAUD Double Rod Cylinder SAUD63X80S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD63X80S is a genuine double-acting profile-type standard air cylinder with a Ø63mm bore and 80mm 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 SAUD63X80S
The AirTAC SAUD63X80S is a double-acting, double-rod profile cylinder. A rod protrudes from both ends, meaning both chambers use the rod-side area. This yields exactly 1402 N of force each way at 0.5 MPa. The extruded aluminum barrel keeps the unit shorter than an ISO 15552 cylinder of the same 63 mm bore. It features a 3/8 inch port and an M16x1.5 rod thread.
This -S variant includes a piston magnet for CMSG, DMSG, or EMSG switches. The equal push and pull output makes it ideal for anti-rotation guidance or carrying a sensor cam on the back rod. Based on the 1402 N output, your safe working load is roughly 841 N, and it can vertically lift about 71 kg with a 2:1 margin. Viton H seals can raise the operating temperature to 150 C.

Where the Airtac SAUD Double Rod Cylinder SAUD63X80S Is Used
Twin Tool Transfer
Drives two opposing grippers simultaneously with equal 1402 N force, ensuring perfectly synchronized part handling without rotation.
Cam-Triggered Cutting
Uses the extended back rod to physically trip an external limit switch, confirming blade position before the cutting stroke begins.
Balanced Vertical Lift
Lifts payloads up to 71 kg with a 2:1 safety margin, relying on the symmetrical rod area to prevent piston drift under gravity.
Is the Airtac SAUD Double Rod Cylinder SAUD63X80S the Right Cylinder?
Choose this 63 mm bore when you need 1402 N equal force both ways. Step down to the 50 mm bore for 825 N, or up to the 80 mm bore for 2268 N if your payload is heavier. A double rod is the right call for synchronized twin tooling, non-rotating anti-twist loads, or back-end switch tripping. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. At 80 mm stroke, side loads are minimal, but always use external guides for longer strokes. The -S magnet enables position sensing.
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 SAUD63X80S 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 feeds both chambers equally.
No. A plain SAUD cylinder does not hold load without live air; the adjustable cushion only decelerates near stroke end. For a held load, you must add an external rod lock or a pilot-operated check valve.
