An improved self-contained roller bearing assembly includes coaxially disposed inner and outer bearing race members (or assemblies), at least one circumferential row of cylindrical rollers and at least one circumferential row of tapered rollers disposed radially between the inner and outer bearing members (or assemblies). The inner and outer bearing race members (or assemblies) include generally recessed and generally non-recessed annular cylindrical raceway surfaces, as well as generally recessed and generally non-recessed annular conical raceway surfaces. At least one of the inner and outer bearing race members or assemblies includes at least a pair of separate race member portions that may optionally be spaced axially from one another by one or more axial spacer members. The separate race member portions and the axial spacer members are fully reversible, with the separate race member portions being interchangeable end-to-end with one another, without affecting the predetermined desired bearing clearance and end play for which the race member portions and the axial spacer or spacers were sized and machined.
