Method for manufacturing bearing shells involves making imprinted marking on inside face of blank before applying anti-friction coating, with mark deep and wide enough to remain visible after coating is applied

摘要

The method involves making blanks from a strip material and shaping them into the shell. Before applying an anti-friction coating (6) to the inside at least one imprinted marking (7) is made in the inside face of the blank whereby the depth and width of the mark is so large that the contour of the imprinted mark remains even after the coating has been applied. The imprinted mark is made during stamping out the blank. Independent claim describes anti-friction bearing shell with imprinted marking inside a strip-formed region (3) on the inside underneath the dividing face (2).
