Airtac SAUD Double Rod Cylinder SAUD50X220S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD50X220S is a genuine double-acting profile-type standard air cylinder with a Ø50mm bore and 220mm 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 SAUD50X220S
The AirTAC SAUD50X220S is a double-acting, double-rod profile cylinder. A 20mm rod exits both ends of the hard-anodized aluminum extruded barrel, meaning both faces use the rod-side piston area. Output is therefore identical in both directions at 825 N each way at 0.5 MPa. This profile body is notably shorter than an ISO 15552 cylinder of the same bore. The 1/4" port and M16x1.5 rod thread are fixed by the 50mm bore.
Because the -S suffix denotes a built-in piston magnet, this model directly supports CMSG, DMSG and EMSG switches. You can also mount a sensor cam or trip a switch on the back rod. A practical computed insight: the safe working load is roughly 495 N (about 60% of the 825 N figure), translating to a vertical lift capacity of about 42 kg with a 2:1 safety margin. The standard TPU seals handle -20 to +70 C, while a Viton H option extends this to 0-150 C.

Where the Airtac SAUD Double Rod Cylinder SAUD50X220S Is Used
Twin-Tool Transfer
Drives two opposing end-effectors simultaneously with identical 825 N force, ensuring perfectly synchronized part transfer between machining stations.
Anti-Rotation Lift
Lifts vertically guided payloads up to 42 kg using the dual rods to prevent twist and droop without needing external linear bearings.
Dual-End Sensing
Uses the front rod for the primary work stroke while the rear rod carries a cam to trigger CMSG or DMSG switches for precise timing.
Is the Airtac SAUD Double Rod Cylinder SAUD50X220S the Right Cylinder?
When sizing this double-rod unit, consider the neighboring bores: the 40mm version yields 528 N both ways at 0.5 MPa, while the 63mm version provides 1402 N. The 50mm bore here hits a sweet spot at 825 N. Choose this twin-rod architecture when your mechanism requires strict anti-rotation guidance, needs to drive two tools in opposite directions simultaneously, or benefits from rear-rod sensing. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. With a 220mm stroke, you should always use an external guide to absorb side loads and prevent binding. The -S magnet enables electronic or reed position sensing.

- ✓ 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 SAUD50X220S FAQ
The force is equal both ways because the 20mm rod exits both ends. It generates 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and 1484 N at 0.9 MPa in both extend and retract directions.
No, a plain double-rod cylinder drifts without live air; the 21mm adjustable cushions only decelerate near stroke end. For load holding, install an external rod lock or pilot-operated check valve.
