Wheel Support Assembly

A wheel support assembly for use with a vehicle is disclosed that comprises a vehicle mount coupleable to the vehicle, a recess formed in the vehicle mount, a bearing seated at least partially within the recess, an axle engaged with the bearing and extending away from the bearing, and a wheel supported by the axle. To inhibit the transfer of heat from the bearing to the wheel the bearing is in thermal communication with the vehicle mount and the wheel is spaced apart from the bearing along a longitudinal axis of the axle. The vehicle mount is configured as a heat sink such that a larger portion of the heat generated by the bearing is transferred to the heat sink as compared to the portion transferred to the axle.
