Abstract
A bearing assembly supports a shaft. The bearing assembly comprises an outer bearing race and an inner bearing race. Each bearing race has a race track in which a plurality of rolling elements are located. The inner bearing race is split into two halves. The two halves of the split bearing race are interconnected by curvic teeth. The curvic teeth constrain relative movement between the two halves of the split bearing race and maintain concentricity of the bearing race.
