Airtac SAUD Double Rod Cylinder SAUD63X85S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD63X85S is a genuine double-acting profile-type standard air cylinder with a Ø63mm bore and 85mm 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 SAUD63X85S
The AirTAC SAUD63X85S is a double-acting, double-rod profile cylinder. A rod protrudes from both ends, meaning both faces use the rod-side piston area. This yields equal push and pull force, delivering 1402 N 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.
This -S variant includes a piston magnet for CMSG, DMSG or EMSG switches. The 3/8 inch port and M16x1.5 rod thread handle flows efficiently. From the 1402 N baseline, your safe working load is roughly 841 N, translating to a 71 kg vertical lift with a 2:1 margin. A high-temp Viton H seal can extend operation to 150 C.

Where the Airtac SAUD Double Rod Cylinder SAUD63X85S Is Used
Twin-Tool Transfer
Drives two opposing grippers simultaneously with identical 1402 N force, ensuring parts transfer without rotational twist.
Rear-Cam Sensing
Uses the back rod extension to physically trip a limit switch or carry a CMSG sensor cam in tight machinery spaces.
Balanced Pinching
Applies equal clamping pressure from both directions for centering thin metal panels during a precision welding process.
Is the Airtac SAUD Double Rod Cylinder SAUD63X85S the Right Cylinder?
Choose this 63 mm bore when your mechanism requires anti-rotation guidance, twin tooling, or a rear cam to trip a switch. It outputs 1402 N both ways at 0.5 MPa. Sizing up to the 80 mm bore increases that equal force to 2268 N, while dropping down to the 50 mm bore reduces it to 825 N. Mounting is limited to Basic, FA flange, and LB foot, matching the AirTAC SC series. The 85 mm stroke is short, but for any stroke over 300 mm you should add external guide rails to prevent side-load binding.

- ✓ 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 SAUD63X85S FAQ
Because the double rod occupies area on both faces, 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 cushions only decelerate the piston near the stroke ends; they do not lock the position. For secure load holding on air loss, install an external rod lock or a pilot-operated check valve.
