Abstract
A method of forming a ball bearing assembly capable of withstanding, in a non-operating mode, an axial load exceeding a predetermined axial load at which bearing damage would otherwise occur includes the following steps: assembling a bearing assembly with at least one set of annular bearing races and, disposed therebetween, a multiplicity of balls, each race having a face surface aligned transversely to the axis of rotation of the bearing assembly, (b) mounting the bearing with the first race fixed axially, (c) applying an axially directed load against the second race of a predetermined magnitude selected to be greater than the intended operating preload and less than a bearing damaging load, (d) grinding the face surfaces of the bearing races flush, (e) releasing the force, and (f) in operating condition, providing a stop ring having a flat stop face surface opposed to the face surfaces of the bearing races, the face surface of the first bearing race disposed in engagement with the stop face surface and the face surface of the second bearing race, under normal axial load, spaced therefrom. Application of an axial load upon the bearing assembly causes the face surface of the first …
