An improved reliability roller bearing having an outer ring; inner ring made up of three separable elements, that is, two guide rails and an inner raceway; a plurality of rollers interposed between the inner ring and the outer ring and a cage for supporting the rollers therebetween. Both guide rails entrap up to 60% of the roller diameter. In addition, the roller bearing incorporates therein a novel lubricant distribution system which is formed within the guide rails. Even distribution of lubricant is obtained by a centrifugally fed weir built into both guide rails.
