Method for producing an internally structured plain bearing bushing, having the following temporally sequential method steps a) providing a plain bearing bushing having at least one bearing region which is formed as a hollow cylinder having an inner surface and which has an outer diameter and an inner diameter, wherein the plain bearing bushing is a plain bearing bushing which is rolled from strip material and has a butt joint which extends parallel with the axis thereof, b) providing an external tool having a through-opening whose smallest inner diameter is smaller than the outer diameter of the bearing region of the plain bearing bushing provided, wherein the through-opening has at least at one side a conical expansion whose maximum inner diameter is greater than the outer diameter of the bearing region of the plain bearing bushing provided, c) providing an internal tool which has an integral cylindrical operating region having an outer surface having a structure, wherein the maximum outer diameter of the operating region is smaller than the inner diameter of the bearing region of the plain bearing bushing provided, d) introducing the internal tool into the bearing region of the plain bearing bushing, e) introducing the plain bearing bushing and the internal tool into the conical expansion of the through-opening of the external tool, f) pressing the plain bearing bushing using the internal tool into the through-opening of the external tool with the outer and inner diameter of the bearing region of the plain bearing bushing being reduced so that the inner surface of the bearing region is pressed onto the outer surface of the internal tool and an internal structure is impressed into the inner surface of the bearing region as a negative form of the structure of the outer surface of the internal tool, g) removing the plain bearing bushing from the through-opening of the external tool, h) radially expanding the plain bearing bushing so that the internal tool can be removed from the plain bearing bushing. a) providing a plain bearing bushing having at least one bearing region which is formed as a hollow cylinder having an inner surface and which has an outer diameter and an inner diameter, wherein the plain bearing bushing is a plain bearing bushing which is rolled from strip material and has a butt joint which extends parallel with the axis thereof, b) providing an external tool having a through-opening whose smallest inner diameter is smaller than the outer diameter of the bearing region of the plain bearing bushing provided, wherein the through-opening has at least at one side a conical expansion whose maximum inner diameter is greater than the outer diameter of the bearing region of the plain bearing bushing provided, c) providing an internal tool which has an integral cylindrical operating region having an outer surface having a structure, wherein the maximum outer diameter of the operating region is smaller than the inner diameter of the bearing region of the plain bearing bushing provided, d) introducing the internal tool into the bearing region of the plain bearing bushing, e) introducing the plain bearing bushing and the internal tool into the conical expansion of the through-opening of the external tool, f) pressing the plain bearing bushing using the internal tool into the through-opening of the external tool with the outer and inner diameter of the bearing region of the plain bearing bushing being reduced so that the inner surface of the bearing region is pressed onto the outer surface of the internal tool and an internal structure is impressed into the inner surface of the bearing region as a negative form of the structure of the outer surface of the internal tool, g) removing the plain bearing bushing from the through-opening of the external tool, h) radially expanding the plain bearing bushing so that the internal tool can be removed from the plain bearing bushing.
