ABSTRACT:
A wheel for a skating apparatus is operably carried on a truck so as to selectively rotate in a given direction or in both directions. A bearing assembly rotatably mounts the wheel on one end of an axle outwardly projecting from a skate truck. The bearing assembly includes a pair of races between which bearings are rollably disposed. An adjustable bearing assembly is operably coupled between the opposing surfaces of the truck and the inside of the wheel. Bearings in this latter assembly are rollable in a circular cage having the bearing surfaces engagable with a flat raceway carried on the truck wherein the wheel rotates in a first direction when the bearing engages with a circular portion of an eccentric and ceases rotation when the bearing engages with a flattened ramp portion of the eccentric. In an alternate embodiment the first mentioned bearing assembly includes the eccentric raceway on one side of the cage holding the bearings and the flat surface race on the opposite side.
