Abstract
In one embodiment a bearing comprises an outer ring surrounding a central hub with inner and outer portions. In this embodiment, the inner portion is longer than the outer portion. The outer ring may be positioned between the inner portion and the outer portion of the central bearing hub. The outer ring may be offset relative to the center of the overall length of the bearing. A drive wheel may comprise a hub, a wheel portion, and a pair of bearings. In this embodiment, the wheel portion may be attached to an outer surface of the hub. The first bearing and the second bearing may be positioned within the hub such that an end of the first bearing abuts an end of the second bearing. In some embodiments, at least a portion of the first end of the hub and at least a portion of the second end of the hub are crimped inward.
