Abrégé
A process is disclosed for manufacturing flat bearing shells. A strip of material (2) is cut into bearing shell sections (26), these sections are bent into a semicircular shape, and the outer and inner sides (88, 58), as well as the parting surfaces (52) of the thus obtained bearing shells are calibrated. An oil groove (14) is shaped on the inner side (58) from parting surface (52) to parting surface (52). For the oil groove to be more easily shaped with a less complex milling tool, the oil groove (14) is continuously shaped, in particular milled, broached or sandblasted in the strip of material (2) before the strip of material is cut into bearing shell sections (26), and a cutting die (6) which matches the cross-section profile of the strip of material (2) after the oil groove (14) is milled is used to cut the strip of material into bearing shell sections (26).
