Abstract
A bearing for an archery bow having an inner race and an outer race. The inner and outer races can define two or more raceways at least partially retaining respective sets of balls. In some examples, the bearing can be disposed within a cam or eccentric of the archery bow. In some examples, two or more bearings can be disposed within the cam. Each respective inner race of the two or more bearings can contact one another to form a continuous load path in some examples.
