Airtac SAUD Double Rod Cylinder SAUD63X550S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD63X550S is a genuine double-acting profile-type standard air cylinder with a Ø63mm bore and 550mm 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 SAUD63X550S
The AirTAC SAUD63X550S 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 output force in both directions, delivering 1402 N each way at 0.5 MPa. The extruded aluminium barrel keeps the unit shorter than an ISO 15552 cylinder of the same bore. It features a 3/8 inch port and a built-in magnet for position sensing.
With a 550 mm stroke, external guide rails should support the load to prevent rod bending and absorb side-load forces. The equal push and pull force makes it ideal for anti-rotation guidance and twin-tool setups. Based on the 0.5 MPa rating, the safe working load is roughly 841 N, which translates to a vertical lift capacity of about 71 kg with a 2:1 safety margin. For high-temperature environments up to 150 C, specify the Viton H seal option.

Where the Airtac SAUD Double Rod Cylinder SAUD63X550S Is Used
Synchronized Twin-Tool Transfer
Drives two parallel workpieces simultaneously with identical 1402 N force in both directions, ensuring perfectly timed material transfer without rotation.
Precision Edge Guiding
Uses the inherent anti-twist rigidity of the dual rods to hold a straightening fixture steady over a 550 mm travel, preventing yaw during heavy stock alignment.
Dual-End Switch Cam Duty
Carries a CMSG or DMSG sensor target on the rear protruding rod, freeing the primary front tool face to perform stamping while tracking position electronically.
Is the Airtac SAUD Double Rod Cylinder SAUD63X550S the Right Cylinder?
Choose this 63 mm bore when you need 1402 N of equal bi-directional force. If your application requires less thrust, the neighbouring 50 mm bore provides 825 N both ways. If you need more power, step up to the 80 mm bore for 2268 N. A double-rod design is the right call when you need synchronized motion, non-rotating anti-twist guidance, or wish to mount a sensor cam on the back rod. Mounting options are limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. This unit includes the -S magnet for CMSG, DMSG, and EMSG switches. Because the stroke is 550 mm, always use an external guide to prevent rod bending under side loads.
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 SAUD63X550S FAQ
Because the piston rod exits both ends, the push and pull forces are equal. This 63 mm bore cylinder outputs 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and 2523 N at 0.9 MPa in both directions. It never produces a larger single-rod push value.
No, a plain double-rod cylinder drifts when air is removed or the valve is centered. The adjustable 21 mm air cushions only decelerate the piston near the stroke ends and do not act as a brake. For secure load holding, install an external rod lock or a pilot-operated check valve.
