Airtac SAUD Double Rod Cylinder SAUD50X650S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD50X650S is a genuine double-acting profile-type standard air cylinder with a Ø50mm bore and 650mm 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 SAUD50X650S
The AirTAC SAUD50X650S is a double-acting, double-rod profile cylinder. A 20mm rod exits both ends, meaning push and pull forces are identical at 825 N each way at 0.5 MPa. The extruded aluminum barrel keeps the unit shorter than an ISO 15552 cylinder of the same bore. It features a 1/4 inch port and M16x1.5 rod threads.
Because the rear rod protrudes, it easily carries a switch cam for position sensing. With a 650mm stroke, external guides are recommended to prevent rod bending under side loads. Based on the 0.5MPa rating, the safe working load is roughly 495 N, allowing a vertical lift of about 42kg with a 2:1 margin. The -S suffix means a piston magnet is built in for CMSG, DMSG, or EMSG switches.

Where the Airtac SAUD Double Rod Cylinder SAUD50X650S Is Used
Twin-Tool Shuttle
Drives two opposing pick heads simultaneously with equal push and pull thrust for balanced part transfer.
Anti-Rotation Lift
Raises and lowers a 42kg vertical payload using the dual rods to prevent mechanical twist without external guides.
Cam-Triggered Sorting
Uses the extended back rod to trip a CMSG reed switch, confirming full extension on a 650mm diverter gate.
Is the Airtac SAUD Double Rod Cylinder SAUD50X650S the Right Cylinder?
Choose this 50mm bore (825 N equal force) over the smaller 40mm (528 N) if you need extra thrust, or step up to the 63mm (1402 N) for heavier loads. A double-rod design is ideal when you need anti-rotation accuracy, twin tooling, or back-end sensing. Mounting is limited to Basic, FA, and LB styles compatible with the AirTAC SC series. At 650mm stroke, always use external guides to manage side loads and prevent rod bending.
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 SAUD50X650S FAQ
The force is equal in both directions because rods exit both ends. It outputs 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and 1484 N at 0.9 MPa. The 1/4 inch port supplies air to achieve these figures.
No, the air cushions only decelerate the piston near the stroke ends and do not lock the position. To prevent drifting on air loss, you must add an external rod lock or a pilot-operated check valve.
