Airtac SAUD Double Rod Cylinder SAUD50X650
The AirTAC Airtac SAUD Double Rod Cylinder SAUD50X650 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 SAUD50X650
The AirTAC SAUD50X650 is a double-acting, double-rod profile cylinder. A rod protrudes from both ends, meaning the push and pull output is identical at 825 N each way at 0.5 MPa. The extruded aluminium body is noticeably shorter than a standard ISO 15552 unit of the same bore. It features a 1/4 inch port, M16x1.5 rod thread, and adjustable air cushions at both ends.
Because this SKU lacks the -S magnet suffix, it cannot accept CMSG, DMSG, or EMSG magnetic switches. For sizing, the safe working load is roughly 495 N (about 60 percent of the 0.5 MPa figure), translating to a vertical lift capacity of approximately 42 kg with a 2:1 safety margin. A high-temperature Viton H seal option can extend the operating range up to 150 C.

Where the Airtac SAUD Double Rod Cylinder SAUD50X650 Is Used
Synchronized Transfer
Drives two parallel pick-and-place fingers simultaneously from a single piston, keeping payloads balanced without twisting.
Twin Spindle Drilling
Powers dual machining heads from opposite rod ends, ensuring both tools advance and retract at the exact same depth.
Dual Lane Diverting
Mounts opposing diverting arms on each rod end to push products on two adjacent conveyor lanes simultaneously.
Is the Airtac SAUD Double Rod Cylinder SAUD50X650 the Right Cylinder?
Choose this 50 mm bore if you need synchronized motion, twin tooling, or anti-twist guidance. It delivers 825 N of equal force in both directions. If you need less force, the 40 mm bore provides 528 N; if you need more, step up to the 63 mm bore which yields 1402 N. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. Because the 650 mm stroke is relatively long, always use external guides to prevent rod bending and excessive side loads. Note that this non-magnetic version cannot host position sensors.
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 SAUD50X650 FAQ
The force is equal in both directions because the double-rod design uses the rod-side area on both faces. It outputs 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and 1484 N at 0.9 MPa. The unit features a 1/4 inch port.
No, a plain double-rod cylinder drifts when air pressure is lost or the valve is centered. The adjustable cushion only decelerates the piston near the stroke ends and does not act as a brake. Use an external rod lock or pilot-operated check valve for secure load holding.
