Airtac SAUD Double Rod Cylinder SAUD50X220
The AirTAC Airtac SAUD Double Rod Cylinder SAUD50X220 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 SAUD50X220
The AirTAC SAUD50X220 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 an identical push and pull output of 825 N each way at 0.5 MPa. The extruded hard-anodized aluminum barrel makes the unit shorter than an ISO 15552 cylinder of the same bore.
This SKU has no internal magnet, so it cannot accept CMSG, DMSG, or EMSG sensors. The 1/4" port and M16x1.5 rod thread are fixed by the 50 mm bore. Based on the 825 N output, the safe working load is roughly 495 N, which translates to a vertical lift capacity of about 42 kg with a 2:1 safety margin.

Where the Airtac SAUD Double Rod Cylinder SAUD50X220 Is Used
Twin-Tool Transfer
Drives two opposing pickers simultaneously with perfectly matched force for balanced part shuttling.
Anti-Twist Lift
Lifts delicate 42 kg fixtures vertically without rotational drift thanks to the dual-rod geometry.
Symmetric Clamping
Applies equal clamping pressure from both directions to keep thin-walled housings centered.
Is the Airtac SAUD Double Rod Cylinder SAUD50X220 the Right Cylinder?
Choose this 50 mm bore double-rod unit when you need strict anti-rotation guidance or twin-tool synchronization. Stepping down, the 40 mm bore provides 528 N each way at 0.5 MPa; stepping up, the 63 mm bore delivers 1402 N. This model lacks the -S magnet option, so external mechanical switching is required. Mounting is limited to Basic, FA, and LB styles (compatible with the AirTAC SC series). For this 220 mm stroke, ensure external guide rails support any side loads to prevent binding.
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 SAUD50X220 FAQ
The force is equal in both directions because both faces carry a rod. It generates 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and 1484 N at 0.9 MPa.
No. A plain SAUD cylinder drifts without live air, as the end cushions only decelerate the piston near stroke end. For a held load, install an external rod lock or pilot-operated check valve.
