This interference fit bearing is divided into an outer and an inner bearing assembly. The outer bearing assembly has an outside radial dimension measured from the center of the bearing which is at least 0.002 inches larger than the opening into which it will be interference fit. The inside radial dimension of the outer bearing assembly will be larger than the outer radial dimension of the inner bearing assembly prior to insertion of the bearing into the receiving hole in the interference fit. When the outer and inner bearing assemblies of the interference fit bearing are pressed into the hole in the receiving load bearing element, the compression of the bearing by the receiving hole will act to force the outer bearing assembly into the proper tolerance fit with the inner bearing assembly of the bearing. At the same time the receiving hole is prestressed by the interference fit which will dramatically decrease fretting and stress corrosion which would otherwise occur under cyclic loads in the load bearing element at its interface with the bearing.
