Airtac SAUD Double Rod Cylinder SAUD50X800S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD50X800S is a genuine double-acting profile-type standard air cylinder with a Ø50mm bore and 800mm stroke, 1/4" 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 SAUD50X800S
The AirTAC SAUD50X800S is a double-acting, double-rod profile cylinder. A rod exits both ends, meaning push and pull forces are identical at 825 N each way at 0.5 MPa. The extruded aluminium barrel keeps the body shorter than a standard ISO 15552 unit of the same bore. This -S variant includes a piston magnet for CMSG, DMSG or EMSG switches.
With an 825 N equal force, the safe working load is roughly 495 N, yielding a vertical lift capacity of about 42 kg with a 2:1 margin. The 1/4" port and M16x1.5 rod thread match the 50 mm bore specification. Because the stroke is 800 mm, external guides are recommended to prevent rod bending under side loads. Viton H seals can extend the -20 to +70 C temperature range up to 150 C.

Where the Airtac SAUD Double Rod Cylinder SAUD50X800S Is Used
Synchronized Dual Grippers
Drives two opposing grippers simultaneously from one piston, keeping pick-and-place movements perfectly aligned without torsional twist.
Anti-Rotation Push Station
The twin rods prevent the end tooling from twisting during the 800 mm extension, ensuring precise vertical contact on pressing tasks.
Rear Cam Sensing
Uses the protruding back rod to trip a CMSG or DMSG switch, freeing the front rod entirely for load engagement in tight cells.
Is the Airtac SAUD Double Rod Cylinder SAUD50X800S the Right Cylinder?
Choose this 50 mm bore when you need 825 N of force in both directions. If your application requires less thrust, the 40 mm bore provides 528 N both ways; if you need more, step up to the 63 mm bore for 1402 N. A double rod is the right call for anti-rotation guidance, driving twin tooling, or mounting a switch cam on the back rod. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. At 800 mm stroke, always support the load with external linear guides to avoid rod bending. The -S magnet allows solid-state or reed sensor tracking.

- ✓ 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 SAUD50X800S FAQ
Because it is a double-rod cylinder, the force is equal in both directions: 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and 1484 N at 0.9 MPa. The 1/4" port supplies air to both chambers equally.
No, the adjustable air cushions only decelerate the piston near the stroke ends; they do not lock the load. For holding a load vertically over the 800 mm travel, you must add an external rod lock or pilot-operated check valve.
