Abstract
A bearing shell for heavily loaded bearings with a rolled strip interfere or force fit lining comprises a generally annular body with an axial bore fitted with a lining in which a shaft turns. The lining comprises a 2 mm thick rectangle of rolled steel strip at least the bearing surface of which has been surface hardened to a depth of approximately 0.5 mm by nitriding or by carburizing and quenching. The ends of the rolled strip bear on each other. The strip is an interference or force fit in the bore of the body and has an excess length relative to the developed length of a neutral fiber of an unstressed lining between 0.3 and 9%.
