A bearing element having a metallic body with a bearing contact curved surface portion, at least one laser shock peened surface encompassing at least a portion of the contact surface portion, and a region having deep compressive residual stresses imparted by laser shock peening (LSP) extending into the body from the laser shock peened surface. The present invention may be used for rolling elements such as ball bearing elements or elongated roller elements and for static elements such as races which may be singular or split and may have circumferentially spaced oil feed passages radially disposed therethrough.
