Abstract
A generally cylindrical metallic member of hardened steel, especially a race for a journal bearing, is fitted into or around a supporting element of relatively deformable metal, such as structural steel, having a face perpendicular to the cylinder axis. The hardened metallic member has a peripheral groove into which some of the material of the supporting element is extruded by indenting the perpendicular face, preferably by a circular array of notches.
