A self-lubricating roller bearing is provided. The roller bearing includes an inner race, an outer race, and a plurality of rollers between the inner and outer races. Each of the inner race and the outer race includes a bearing surface for contact with the rollers. The bearing surface of one or more of the inner race, the outer race, and the rollers has one or more laser hardened areas and one or more non-laser hardened areas arranged in a predetermined pattern. The one or more non-laser hardened areas create dry lubricant for the roller bearing upon wear thereof.
