Abstract

A bearing frame or cylinder head cover of an internal combustion engine may include at least one camshaft mounted therein. The camshaft may be tunnel-mounted in at least two bearing openings arranged along a bearing channel. At least two radial bearings may be arranged on the camshaft, each of the radial bearings having an outer bearing shell. The outer bearing shells of the at least two radial bearings may include different outer diameters, each of the respective outer diameters adapted to be complementary to an inner diameter of the associated bearing opening. The inner diameters of the bearing openings may decrease in a direction of assembly of the camshaft along the bearing channel.
