ABSTRACT:
A ball bearing comprising a substantially circular inner race having a first center, a substantially circular outer race having a second center substantially surrounding the inner race. The outer race is made up of a base and a pair of radially inwardly extending flanges which are spaced apart axially from one another. The flanges extend further inwardly at or adjacent the top of the bearing than they do from the bottom of the bearing. Rollable balls are held by the races in the usual manner. The provision of the extended upper flange permits greater wear of the balls before the bearing fails. This increases the times between the need for bearing changes.
