Abstract
The present invention relates generally to a hub for a skate wheel. The hub includes a central core member defining a bore for receiving an axle. A central axis of rotation passes through the center of the bore. The hub also includes first and second anchors extending radially outward from the core and disposed in axially spaced-apart relation such that an outwardly opening channel is defined between the first and second anchors. The first anchor includes a plurality of first radial projections separated by first spacing gaps. The second anchor includes a plurality of second radial projections separated by second spacing gaps. The first and second radial projections are staggered relative to each other about the central axis of rotation such that the first radial projections are aligned with the second spacing gaps and the second radial projections are aligned with the first spacing gaps.
