  • Patent number: 8602657
    Abstract: A bearing cage defines an overall axial length and includes a first end portion defining a first contact surface extending at a radially-outermost diameter of the bearing cage a first axial contact length, and a second end portion spaced a distance from the first end portion and defining a second contact surface extending at the radially-outermost diameter of the bearing cage a second axial contact length. The bearing cage further includes a plurality of spanning members extending between the first and second end portions to define a spanning member axial contact length defined at the radially-outermost diameter of the bearing cage by at least one contact pad. The bearing cage produces a total contact ratio, defined as the ratio of the sum total of the first axial contact length, the second axial contact length, and the spanning member axial contact length to the overall axial length, of at least 0.380.
