The patent describes a cam assembly for archery bows featuring a bearing with an inner race that spans the entire width and defines a continuous load path, along with an outer race that includes two discrete raceways for ball sets. This design enhances the performance and stability of the cam mechanism in archery bows by allowing for smoother rotation and improved load distribution.

Claim 1

1 . A cam assembly for an archery bow, comprising: a cam defining a bore spanning a width of the cam; an axle; and a bearing rotatable about the axle, the bearing comprising: an inner race spanning an entirety of the width, the inner race defining a continuous load path across the width; an outer race defining a first raceway and a second raceway discrete from the first raceway; a first set of balls disposed within the first raceway and between the inner race and the outer race; and a second set of balls disposed within the second raceway and between the inner race and the outer race. a cam defining a bore spanning a width of the cam; an axle; and a bearing rotatable about the axle, the bearing comprising: an inner race spanning an entirety of the width, the inner race defining a continuous load path across the width; an outer race defining a first raceway and a second raceway discrete from the first raceway; a first set of balls disposed within the first raceway and between the inner race and the outer race; and a second set of balls disposed within the second raceway and between the inner race and the outer race. an inner race spanning an entirety of the width, the inner race defining a continuous load path across the width; an outer race defining a first raceway and a second raceway discrete from the first raceway; a first set of balls disposed within the first raceway and between the inner race and the outer race; and a second set of balls disposed within the second raceway and between the inner race and the outer race.
