Airtac SAUD Double Rod Cylinder SAUD63X20
The AirTAC Airtac SAUD Double Rod Cylinder SAUD63X20 is a genuine double-acting profile-type standard air cylinder with a Ø63mm bore and 20mm stroke, 3/8" 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 SAUD63X20
The AirTAC SAUD63X20 is a double-acting, double-rod profile cylinder. A 20mm stroke is driven by a 63mm bore with a 3/8 inch port. Because a rod exits both ends, the output is equal in both directions, delivering 1402 N each way at 0.5 MPa. The extruded aluminium barrel makes it shorter than an ISO 15552 cylinder of the same bore.
This unit lacks a magnet, so it cannot take a magnetic switch. For sizing, the safe working load is roughly 841 N, yielding a vertical lift capacity of about 71 kg with a 2:1 margin. The standard TPU seals handle -20 to +70 C, while a Viton H option extends this to 150 C.

Where the Airtac SAUD Double Rod Cylinder SAUD63X20 Is Used
Twin-Tool Stamping
Drives two synchronized forming punches from opposite rod ends, ensuring perfectly balanced hitting force on thin metal blanks.
Dual Diverter Flaps
Actuates opposing guide gates simultaneously on a sorting line, pushing packages cleanly into separate lanes without twisting.
Anti-Rotation Clamp
Holds a machined block securely during milling. The dual rods prevent jaw rotation under heavy lateral cutting loads.
Is the Airtac SAUD Double Rod Cylinder SAUD63X20 the Right Cylinder?
Choose the 63mm bore for 1402 N of equal bidirectional force at 0.5 MPa. If you need less thrust, the 50mm bore provides 825 N both ways; for more power, step up to the 80mm bore for 2268 N. A double rod is the right call for anti-rotation guidance or driving twin tooling. Mounting is limited to Basic, FA, and LB types, matching the AirTAC SC series. Since this specific SKU has no magnet (-S), you cannot mount CMSG or DMSG sensors. Note that the 20mm stroke is very short, so side-load guides are not a concern here.
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 SAUD63X20 FAQ
The force is equal both ways because it is a double-rod design. It outputs 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and 2523 N at 0.9 MPa. The 3/8 inch port feeds the 63mm bore to deliver this thrust on both extend and retract strokes.
No. The air cushions only decelerate the piston near the stroke ends; they do not lock the load. If air is lost, the piston will drift. To hold a vertical load securely, you must fit an external rod lock or a pilot-operated check valve.
