Abstract

A roller bearing includes an outer raceway, an inner raceway, and a roller positioned between the outer and inner raceways. The roller bearing also includes a relief contour between the roller and at least one of the outer and inner raceways. The relief contour defines a slope along its length. The slope of the relief contour defines at least one inflection region.
