Abstract
A steering column bearing assembly is disposed between an upper column jacket and a steering control shaft, supporting the steering control shaft for rotation within the upper column jacket. The steering column bearing assembly comprises an inner race, an outer race, and a plurality of ball bearings disposed between the inner race and the outer race, each ball bearing having a ball bearing diameter. The inner race and the outer race define an annular cavity in which the plurality of ball bearings is disposed. The annular cavity has an interior column opening defined between an outer edge surface of the inner race and an inner edge surface of the outer race. The outer edge diameter is less than a sum of the inner edge diameter and the ball bearing diameter.
