Abstract
A bearing assembly having bearing surfaces pre-loaded towards each other, the bearing surfaces being originally made in slightly non-conforming geometry and dimensions over the majority of their surface areas in sliding engagement, the areas of the bearing surfaces in engagement being thus less than the total available areas. During use, and through progressive wear-in of the bearing surfaces in engagement, the bearing surface areas in engagement are progressively enlarged with progressive conformity in geometry and dimension, the conforming surface areas being constantly kept in engagement by the elements in the assembly adapted to provide bearing pre-load.
