Abstract

A mounting assembly for bearing races is provided which enables split races for roller bearings to be fixed on a bearing member in a space-saving system wherein the bearing member includes at least one race groove parallel to two expanding grooves such that narrow webs are left on either side of the race groove. On assembly, for example, of the inner ring of a roller bearing in the race groove, these webs are flanged or crimped against the bearing end faces such that two ends of the axially split bearing race are securely held by appropriate profiling or beveling of the end faces of the race. Assembly may be carried out by inserting a crimping wheel into the expanding grooves and crimping the webs by means of a conically deforming surface. The mounting can be advantageously applied, for example, in connection with an eccentrically drilled bearing bushing for the plain bearings of blanket cylinders in offset printing machines.
