0.5 in. Key Hub
This hub is set with a 1/2 in. bore with two 1/8 in. keyways.
- Description
-
This is the "500EX Key Hub". It is a slightly different version of the 500 Key Hub. It is manufactured differently, 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. Are you having a hard time keeping your sprocket concentric with your hub? This hub is the trick.
The bore is a 1/2 in. hole with two 1/8 in. keyways. Only one keyway is needed to drive most wheels, so the second one is extra.
Also, the keyways are consistently aligned with the mounting holes. -
- Bolt Pattern: 0.204 in. diameter holes on a 1.875 in. bolt circle
- Bore: 0.502 - 0.508 in. diameter bore
- Material: 6063 Aluminum
- Outside Diameter: 2.25 in.
- Weight: 0.3 lbs.
