An axial force is then applied to the inner race ring of the second bearing and the axial force thus applied is measured. The pressure medium is then drained from the interface between the inner race ring and the shaft when a predetermined axial force is reached, whereupon the axial force is relieved. | InventorsAssigneeApplicationNo. 647112 filed on 05/09/1996US Classes:29/898.062, Assembling of race and rolling anti-friction members29/447, By temperature differential (e.g., shrink fit)29/898.07, Mounting29/898.09, Pre-usage process, e.g., preloading, aligning384/563Axially biased race or rollerField of Search29/898.07, Mounting29/898.062, Assembling of race and rolling anti-friction members29/447, By temperature differential (e.g., shrink fit)29/898.09, Pre-usage process, e.g., preloading, aligning384/563, Axially biased race or roller384/585Race fastening meansExaminersPrimary: Schwartz, Larry I.Assistant: Butler, Marc W.
