Abstract
A bearing assembly includes an outer race and an inner race. The outer race has a body extending between a pair of axial faces and defines a radially-inward facing bearing surface. The inner race is received in the outer race and has a radially-outward facing bearing surface that bears against the radially-inward facing bearing surface of the outer race. The radially-outward facing bearing surface has one or more flat surfaces removed from it. These flats on the inner race can reduce the dimensional entry requirements for insertion of the inner race into the outer race and either permits the receiving slots in the outer race to be reduced in dimension (thereby relatively thickening the wall of the outer race, which structurally strengthens the outer races) or permits the receiving slots to be eliminated altogether.
