Patent ID: 8602657

Claim:
A bearing cage having an overall axial length L 1 , the bearing cage comprising: a first end portion, defining a first radially exterior contact surface defined at a radially-outermost diameter of the bearing cage and having a first axial contact length; a second end portion, spaced a distance from the first end portion and defining a second radially exterior contact surface defined at a radially-outermost diameter of the bearing cage and having a second axial contact length; and a plurality of spanning members extending between the first and second end portions, wherein each spanning member defines a spanning member axial contact length C span defined at a radially-outermost diameter of the bearing cage by a pair of distal contact pads and at least one intermediate contact pad disposed therebetween on the spanning member, wherein the at least one intermediate contact pad is wider than either of the pair of distal contact pads, wherein the sum total of the first axial contact length, the second axial contact length, and the spanning member axial contact length C span defines a total contact length C total , and wherein the ratio of the total contact length C total to the overall axial length L 1 is at least 0.380.
