Airtac SAUD Double Rod Cylinder SAUD50X55
The AirTAC Airtac SAUD Double Rod Cylinder SAUD50X55 is a genuine double-acting profile-type standard air cylinder with a Ø50mm bore and 55mm 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 SAUD50X55
The AirTAC SAUD50X55 is a double-acting, double-rod profile cylinder. A 20 mm rod exits both ends of the hard-anodized aluminum barrel, meaning both faces use the rod-side piston area. This yields equal push and pull force of 825 N each way at 0.5 MPa. The extruded profile body is noticeably shorter than a standard ISO 15552 cylinder of the same bore. It features a 1/4 inch port, M16x1.5 rod threads, and adjustable air cushions at both ends.
Because the twin rods resist torsional twist, this model excels at non-rotating guidance and driving two tools at once. Based on the 0.5 MPa output, the safe working load is roughly 495 N, and it can manage a vertical lift of about 42 kg with a 2:1 safety margin. Note this specific SKU lacks a magnet, so it cannot accept CMSG or DMSG sensors. For high-heat environments up to 150 C, specify the Viton H seal option.

Where the Airtac SAUD Double Rod Cylinder SAUD50X55 Is Used
Twin-Tool Stamping
Drives two small forming punches simultaneously from opposite rod ends, ensuring perfectly synchronized contact on thin sheet metal.
Symmetric Diverting Gate
Pushes a diverter blade from either side without twisting, keeping product flow aligned on the sorting belt during bidirectional routing.
Dual-End Ejection
Ejects machined parts from a fixture using the front rod while the back rod trips a mechanical flag to count the cycle.
Is the Airtac SAUD Double Rod Cylinder SAUD50X55 the Right Cylinder?
Choose this 50 mm bore when you need 825 N of equal bidirectional force over a short 55 mm stroke. If your project requires less thrust, the neighboring 40 mm bore provides 528 N both ways; for heavier loads, step up to the 63 mm bore which delivers 1402 N. A double-rod design is the right call for anti-rotation tasks, twin-tool setups, or mounting a switch cam on the back rod. Mounting hardware is compatible with the AirTAC SC series using basic, FA flange, or LB foot brackets. Since this base unit has no magnet, sensing is impossible without upgrading to an -S variant. At a 55 mm stroke, side loads are minimal, but any future build exceeding 300 mm should use external guide rails 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 SAUD50X55 FAQ
Because the 20 mm rod protrudes from both ends, 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. It never produces a larger single-rod push value.
No, this specific SKU does not include a piston magnet. You cannot mount CMSG, DMSG, or EMSG switches on it. You must select an SAUD50X55-S variant if you require magnetic position sensing.
