Airtac SAUD Double Rod Cylinder SAUD63X650S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD63X650S is a genuine double-acting profile-type standard air cylinder with a Ø63mm bore and 650mm 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 SAUD63X650S
The AirTAC SAUD63X650S is a double-acting, double-rod profile cylinder. A 20mm rod exits both ends of the hard-anodized aluminum extruded barrel, meaning both faces use the rod-side piston area. This yields identical push and pull thrust of 1402 N each way at 0.5 MPa. The body is inherently shorter than an ISO 15552 unit of the same bore.
This 63mm bore unit uses a 3/8 inch port and includes a built-in piston magnet (-S) for CMSG, DMSG, or EMSG switches. For sizing, a safe working load is roughly 841 N, and it can vertically lift about 71 kg with a 2:1 margin. A high-temperature Viton H seal option extends operation from 0 to 150 C.

Where the Airtac SAUD Double Rod Cylinder SAUD63X650S Is Used
Twin-Spindle Machining
Drives two opposing machining heads simultaneously, keeping feed rates synchronized via the shared piston.
Dual Transfer Arms
Moves parts across a belt using identical push and pull force, preventing twist during rapid transfers.
Rear-Cam Switch Trip
Uses the protruding back rod to physically trigger an external limit switch or carry a magnetic sensor.
Is the Airtac SAUD Double Rod Cylinder SAUD63X650S the Right Cylinder?
Choose this 63mm bore delivering 1402 N both ways when you need anti-rotation guidance or twin tooling. Step down to a 50mm bore for 825 N, or up to an 80mm bore for 2268 N if your payload requires more thrust. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. Because the 650mm stroke exceeds 300mm, always use external guides to prevent rod bending under side loads. The -S suffix enables electronic 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 SAUD63X650S FAQ
Because the 20mm rod exits both ends, force is equal in both directions: 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and 2523 N at 0.9 MPa. It uses a 3/8 inch port.
No, the adjustable air cushion only decelerates the piston near stroke end. To prevent drift on air loss, install an external rod lock or pilot-operated check valve.
