Airtac SAUD Double Rod Cylinder SAUD63X35S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD63X35S is a genuine double-acting profile-type standard air cylinder with a Ø63mm bore and 35mm 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 SAUD63X35S
The AirTAC SAUD63X35S is a double-acting, double-rod profile cylinder. Because a rod protrudes from both ends, the push and pull forces are identical, yielding 1402 N each way at 0.5 MPa. The extruded aluminum barrel keeps the unit shorter than a standard ISO 15552 cylinder of the same bore. It features a 3/8 inch port and an M16x1.5 rod thread.
This 35 mm stroke unit includes a built-in piston magnet (-S) for CMSG, DMSG, or EMSG switches. The equal force makes it ideal for anti-rotation tasks or driving twin tooling. Based on the 1402 N output, the safe working load is roughly 841 N, translating to a vertical lift capacity of about 71 kg with a 2:1 safety margin. A Viton H seal option can extend the operating temperature up to 150 C.

Where the Airtac SAUD Double Rod Cylinder SAUD63X35S Is Used
Twin-Tool Stamping
Drives two synchronized forming tools from one piston, ensuring parallel contact and equal 1402 N clamping force on both the advance and return strokes.
Anti-Rotation Gauging
Uses the dual rods to prevent twist during precision part measurement, keeping the inspection fixture perfectly aligned without external linear bearings.
Cam-Triggered Sorting
Mounts a switch cam on the rear protruding rod to trip an external sensor, confirming the 35 mm stroke position while the front rod actuates the diverter.
Is the Airtac SAUD Double Rod Cylinder SAUD63X35S the Right Cylinder?
Choose this 63 mm bore when you need 1402 N of equal bidirectional force at 0.5 MPa. If your project requires less power, the 50 mm bore provides 825 N both ways; for heavier loads, the 80 mm bore offers 2268 N. The double-rod design is optimal for non-rotating guidance, carrying a sensor cam on the back rod, or synchronizing two tools. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. The -S suffix enables reed or electronic sensing. Because the stroke is only 35 mm, side-load stress is minimal, but external guides are always recommended for rigid setups. Remember that air cushions only decelerate the piston; use an external rod lock or pilot-operated check valve if you need to hold a load securely without live air.
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 SAUD63X35S FAQ
The force is equal in both directions because it is a double-rod cylinder. 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 end of travel. For secure load holding, install an external rod lock or a pilot-operated check valve.
