  • Documentation
  • Please note this hub is being phased out and replaced by am-4124. It will only be available while supplies last.

    It is a slightly different version of the 500 Hex Hub, as it is extruded. Also, there is a 1.124 in. diameter boss on each side of the hub flange, providing a location for 1.125 in. bore flat sprockets. If you are having a hard time keeping your sprocket concentric with your hub, this should do the trick.

    Want to manufacture your own hub out of the extrusion we make this from? Of course, you do! Get your own 2, 3, or 12-inch sections here, /products/500ex-hex-hub-extrusion.
    • Bolt Pattern: 0.204 in. diameter holes, evenly spaced on a 1.875 in. diameter bolt circle
    • Bore: 0.500 in. [12.7 mm] (1/2) Hex
    • Material: 6063 Aluminum
    • Outside Diameter: 2.25 in.
    • Weight: 0.088 lbs.
